Page 4: Introduction
FIELD LOGGING The KHLOG1 fold-out log tray solves one of the most vexing problems with SOTA, HF Pack, and general field operation: how to conveniently log contacts, in any situation. The tray can be installed on either side of the radio, facilitating left- or right-handed use, and protects the front panel when closed. Filled log sheets can be moved to the bottom of the stack with one hand.. BUILT-IN WHIP The KHATU1 antenna tuner comes with a modified top panel that embodies a whip mounting screw, loading coil, and band-selection switch for use on 20/17/15 meters (and on 30 meters with reduced efficiency). The supplied telescoping whip clips to the side of the rig when not in use. The ATU matches a wide range of loads, and works with the BNC jack as well as the whip. The KH1 covers the full frequency range of each ham band, with power output of 5 watts. Many hours of field operation are ensured by an internal 2.6 AH, 11 V Li-ion battery (KXBT2). An internal charger (KHIBC1) keeps the battery topped off, ready to go when you are. The KH1 has many other features, including: • small speaker • real-time clock (RTC), including both time and date • SWL band: 6.7 - 22.0 MHz (uses SSB mode to copy AM); ATU can be manually tuned to peak signals • CW text decode/display, plus 32K EEPROM for transmit text capture and logging • VFO locking, RIT, and XIT • SSB/CW cross-mode operation • Easy-to-use scan/mini-pan function for signal hunting • firmware upgrades via supplied USB cable and KH1 Utility application • full remote control for specialized applications • light gray enclosure that stays cool, even in bright sunlight • custom, zippered carrying case (ES20) with utility pockets (pg. 12) We hope the KH1 becomes your go-to rig for ultralight adventure travel – whether to exotic locales, to the urban/wilderness boundary, or just to your own back yard.

Page 5: General Precautions
GENERAL PRECAUTIONS • DO NOT PLUG A KXUSB CABLE INTO THE HEADPHONE JACK. The KXUSB cable (used for firmware updates) must be plugged only into the KEY/DATA jack. See 23 for firmware update instructions. • Do not touch the telescoping whip when transmitting, as you could receive an RF burn. Set the whip’s band switch to the center-off position when using the BNC jack. (A telescoping whip and internal matching components are supplied with KHATU1 option.) • Avoid prolonged exposure to moisture. The KH1 can be used in light precipitation, but it is not waterproof. If the log tray is installed, it can be folded over the front panel for moisture resistance. POWER SOURCE EXTERNAL SUPPLY An 8-15 V low-noise power supply, solar panel, or battery can be connected to the external supply jack on the left side. The center pin is (+), as is the white-striped wire on the supplied power cable. The plug can be a Switchcraft model S760 or similar (2.1 mm pin aperture, 5.5 mm barrel diameter). Power output varies with supply voltage. On all bands, maximum power output when running from 11 V is typically 5 watts into a 50 ohm load. (See MENU:ADJ PWR.) The internal and external DC jacks are identical, and are diode-isolated from each other. The jack with the higher voltage will power the transceiver. For example, if you have an internal battery pack plugged in that measures 10.5 V, and an external supply also plugged in that measures 12 V, the external source will supply power. (To display supply voltage and current, see MENU:DISP MODE. A more accurate display of internal battery voltage, along with an amp-hours meter, is also available. See MENU:VBAT.) CHARGE STATUS LED A small LED near the power switch provides power-on and charge status indications, as follows. With a standard KHDC1 DC input module installed (no charger module): • LED is GREEN when the KH1 is ON; UNLIT when it is OFF. (Regardless of which DC jack is in use.) With a KHIBC1 internal battery charger installed: • With no external supply connected: the LED is GREEN when the KH1 is ON; UNLIT when it is OFF. • With an external operating/charging supply connected: the LED is RED when the radio is OFF and charging; ORANGE when the radio is ON and charging; GREEN when charge is complete and the radio is ON; UNLIT when charge is complete and the radio is OFF. See important cautions on next page regarding charging the battery internally or externally. -
Page 6: Internal Battery
INTERNAL BATTERY The KH1 is designed to use an Elecraft KXBT2 lithium-ion battery pack. This pack is rated at 11 V, 2.6 Ah. Thanks to the KH1’s low receive-mode current drain (~50 to 80 mA), the KXBT2 can provide full power output (5 watts) for 4 to 12 hours of typical QRP operation, and up to 50 hours receive-only. The battery pack can be internally recharged at a C/10 rate (~250 mA) using a KHIBC1 internal charger. In this case, charging voltage (nominally ~14 V, minimum 12 V) is provided by the same supply that operates the radio. A KXBC2 external fast-charger can also be used (see cautions below.) CAUTION: IF A KHIBC1 INTERNAL BATTERY CHARGER IS INSTALLED, DO NOT USE ANY BATTERY PACK OTHER THAN THE KXBT2, which has built-in protection circuitry. The use of an incompatible battery pack may be unsafe and may void the warranty. CAUTION: THE BATTERY PACK MUST BE REMOVED FOR RECHARGING WHEN USING A KXBC2 FAST CHARGER. Fast chargers generate RFI, and are NOT suitable for internal charging or for radio operation. Follow the steps below to install or remove the battery pack. The aluminum back cover has a tab that forms a hinge with the plastic top panel. Once the back cover has been rotated to a perpendicular position, slide its metal tab backward about 1/8” (3 mm) before continuing rotation. This will make it easier to close the back cover. • Before installing or removing the battery, turn the KH1 OFF using the small slide switch near the external supply jack. The OFF setting is AWAY from the jack. • Release the KH1’s back panel using the sliding thumb latch near the knobs (red arrow). Then lift open the back cover, sliding it backward while rotating the metal tab through the hinge. • Plug the battery pack into the internal DC jack. Make sure the plug is inserted up to its shoulder. • Place the battery into position, then dress the excess wire to the side approximately as shown. • Slide the thumb latch out of the way of the back panel’s tab, then secure the panel. When unplugging the battery, always use the plastic pull tab. Also press lightly where shown by the blue arrow to ensure that the internal charger or DC input module does not come unplugged due to excessive plug extraction force. -
Page 7: Preserving Clock Time During Charging
The back cover can be completely removed if desired via a thin slot at the back of the plastic hinge. The KH1 includes an amp-hour metering function that allows you to better estimate remaining battery life. See pg. 22. PRESERVING CLOCK TIME DURING CHARGING The KH1 includes a real-time clock (RTC), useful for logging (see MENU:LOGGING). RTC circuitry is powered by the battery or power supply (internal or external). When no power supply or battery is connected, the RTC’s time registers are preserved for about 1 minute by a large-value capacitor. This allows sufficient time to swap batteries without losing the time setting. UTILITY MOUNTING POINTS To enhance versatility, the KH1 provides several utility mounting holes that could be used for future Elecraft accessories or for user-supplied hardware. These are located in three places (see arrows below). BACK COVER, MIDDLE: There are two #2 flat head screw holes in the middle of the back cover. The screw heads must go on the inside, and must be flat head to clear the Li-ion battery pack. BACK COVER, SIDES: There are two #2 holes on each side of the back cover. These are intended for use with the whip mounting clips that are supplied with the KHATU1 option, though they could be used as attachment points for other hardware. Pan head screws must be used in these locations, with the heads on the inside. Any other hardware on the inside (such as a nut or washer) would interfere with circuitry. LOG TRAY: The KHLOG1 log tray (discussed in the next section) has holes at each corner. Some operators may wish to use one of these as an anchor point for a pen lanyard, guarding against loss of the pen when dropped. (A lanyard should not be needed with the supplied mini ball-point pen, however, as it clips securely to the log tray.) -
Page 8: Log Tray And Pen
LOG TRAY AND PEN The KHLOG1 log tray option makes it easy to log contacts while standing, walking, sitting on a trail or rock, or in other situations where there’s no convenient writing surface. Such situations occur often during field use. Sometimes sitting is impossible due to insects, mud, thorns, or other impediments. To use the log tray: • To open the tray, press with a thumb at the locations indicated by the red arrows above, then fold the tray open. The rails also slide out to provide additional clearance for your fingers when operating the KH1 hand-held. Detent locking keeps the tray open, even when upside-down. • The tray can be moved to the either side of the radio. To remove it, push upward on the rails as shown by the blue arrows above, lifting as you pull the rails out. To reinstall, squeeze the forked ends as you insert them into the provided slots. • Print out and precisely trim the desired number of log pages from the file KH1LOGSHEETS.PDF, available on our KH1 web page. We recommend keeping 8 to 10 sheets in the tray, as this stack thickness will provide a moderate friction fit within the upper and lower paper guides. • Unclip the supplied mini ball-point pen to log contacts, record field observations, etc. Note: If you use a Space Pen instead, remove its metal pocket clip and/or cap to allow it to fit. • To change log sheets, slide one sheet off the top, then insert it under the stack, starting with one corner. Indentations are provided for this purpose at the locations near the red arrows. With practice you’ll find this can be done with one hand. • When operating at night, fold the log tray halfway up to let the LCD backlight illuminate the log. -
Page 9: Antennas
ANTENNAS The basic KH1 has a BNC jack intended for use with a 50 ohm load, e.g. a resonant dipole, vertical, or end- fed half-wave. Further information on antennas can be found in the ARRL Antenna Handbook and other sources. Since a basic KH1 does not include the whip, hole plugs are installed at the mounting post and switch. BUILT-IN ATU AND WHIP MATCHING NETWORK The ATU option (KHATU1) greatly enhances the KH1’s versatility. It includes: • an automatic antenna tuner unit (ATU) that works with both the BNC jack and whip • internal whip-matching network for use on 20/17/15 meters (30 m at higher SWR / lower power) • telescoping whip, plus two clips that retain the whip on the side of the KH1 when not in use • 13’ counterpoise wire suitable for 30-15 m use (with the ATU) Like the log tray, the plastic whip clips can be installed on either side of the transceiver, facilitating left- or right-handed operation. Refer to instructions on our KH1 manuals web page. To use the BNC jack: • Set the whip band switch to the center-off position (“x”) to remove RF from the whip mounting post. • The ATU may provide a better SWR, as well as allowing operation on multiple bands. See pg. 17. To use the built-in whip: • Unclip the whip from the radio. • Screw it to the mounting post. • Set the slide switch to the 20 m or 17/15 m position. (This does not disconnect the BNC jack from the ATU. It is always connected.) • Match the whip using the ATU. • Operation on 30 m is possible in the 20 m switch position. SWR may be... -
Page 10: Tips For Using Compact Antennas
It is normal for the whip mounting post to have some “play” when a whip is not connected. The post is pinned internally so that it cannot rotate or be extracted. When a whip is attached, it will be very rigid and stable. TIPS FOR USING COMPACT ANTENNAS The built-in whip can be deployed in seconds and takes very little storage space. It allows your entire KH1 multi-band station to disappear into a small pocket. However, a whip will not be as efficient as a longer antenna mounted well above ground. Rising to this challenge is half the fun...and the tips below can improve your QSO rate. It’s possible to make long-range DX contacts using low power and a whip, especially with advantageous propagation. Contacts of 1,000 to 2,000 miles are quite common. To enhance communications effectiveness when using a whip: • ALWAYS use a counterpoise wire. Without one, your transmitted signal strength will be as much as 20 to 30 dB lower at receiving stations, even if you get an apparent good match using the ATU. • Bring extra wire for outings when band conditions are rough. If there are trees available, a random-wire antenna can be quickly deployed, then matched using the ATU. A BNC-to-binding post adapter (e.g. Elecraft #BNC-BP) can be used to attach an antenna wire to the BNC jack. • Choose locations with an upward slope behind you. This can work as a reflector. • Arrange your ground counterpoise wire for greatest benefit. Deploying the wire toward the favored direction often improves signal strength by several dB, as can draping the wire on top of foliage. You can use the ATU to compensate for changes in wire position and terrain. • Use the Reverse Beacon Network (RBN). This is a global network of receiving stations that may detect your signal and report it on their website. It’s a great tool for optimizing antennas. • Try working strong stations first (S7 or higher). While some stations may be strong due to amplification, more often it’s because of favorable propagation. Also, they typically use low-loss antennas with gain, making them louder — while allowing them to hear you better as well. • Drop in on the QRP “watering holes.” There are QRP calling frequencies, such as 14060.0 kHz, that are used for weak-signal CW work. “HF Pack” operators will often monitor or call on 18157.5 kHz and other standard HF pack frequencies in both SSB or CW modes. Another active group that listens for weak signals is the County Hunters Net, around 14055 kHz. • Plan outings around times when band activity is high, including weekday evenings, weekends, and whenever contests are in progress. Contest examples: CQ DX, ARRL CW, and other “majors”; ARRL Field Day, Winter Field Day (WFD) and other contests emphasizing QRP/field operation; and CWT (very active weekday CW operating events put on by the CWops organization). -
Page 11: Ground Connection And Counterpoise Wire
GROUND CONNECTION AND COUNTERPOISE WIRE A counterpoise wire can be secured to the KH1 using the ground screw beside the BNC jack. The wire can be wrapped around the KH1 and left attached to the ground screw to enable quick deployment. The KHATU1 option is supplied with a 13’ counterpoise wire suitable for use on 20-15 meters. The ATU can be used to achieve resonance and compensate for varying wire lengths, heights, and terrain. The ATU option also comes with two plastic “whip clips” that double as attachment points for the free ends of antenna or ground wire, as well as headphone cables. The arrow in the illustration below-left highlights the serrated gap on one of the whip clips. A wire or thin cable inserted into this gap will be securely retained during transport. SPARE GROUND NUT If the regular ground thumb nut becomes lost, the supplied spare ground nut can be used. This 4-40 hex nut is stored inside the enclosure near the on-off switch, as shown by the arrow in the illustration at above- right. This nut can be pried upward out of its retaining clip using any small tool, including the paddle hex wrench, which is stored nearby (see KEY/DATA JACK, pg. 12). Turn the KH1 OFF when removing the spare ground nut or hex wrench. -
Page 12: Carrying Case
CARRYING CASE The ES20 custom carrying case is shown below (actual color is black). It provides safe storage for the KH1, headphones, spare battery packs, antenna wire, whip, and other small accessories. The ES20’s numerous straps, two D rings, and carabiner add attachment versatility. For example, it can be worn on a belt, vertically. With one hand, the zippered main pocket can then be opened and the radio extracted. KEY/DATA JACK A keying device fitted with a 3.5 mm (1/8”) stereo plug can be plugged into the KEY/DATA jack. This jack doubles as serial port for firmware updates and remote control (see next page). The optional KHPD1 keyer paddle is designed specifically for hand-held operation. It plugs directly into the KEY/DATA jack in the orientations shown below. At left, the KHPD1 is shown in its stored position. At center, the paddle is shown deployed, out of the way of the AF GAIN and VFO knobs. Be sure to insert the paddle’s plug all the way, so that it snaps into the jack. The paddle’s PC board must be resting on the two plastic nubs to the left and right of the jack. Contact spacing of the KHPD1 paddle can be adjusted using the hex wrench stored inside the enclosure (see arrow in the illustration above-right). Each paddle has a set screw in its housing. A fairly wide spacing is recommended for operation in high-vibration or less-stable operating positions. Turn the KH1 OFF when removing or replacing the hex wrench. -
Page 13: Data Connection
DATA CONNECTION The KEY/DATA jack doubles as a serial interface port for upgrading firmware, via the supplied KXUSB cable and our KH1 Utility software application. (MENU:KEY JACK must be set to RS232; the KXUSB cable converts this to USB. The serial interface data rate is fixed at 9600 baud.) The KH1’s user interface can be fully remote-controlled through the KEY/DATA port, using a terminal emulator or custom software application. This capability is intended for factory alignment use, but it could also be used for special applications. (For a list of remote-control commands, refer to the Elecraft KH1 Programmer’s Reference.) When the KEY/DATA jack is being used for remote control, it is not available for use with a keying device. However, there’s a remote-control command (HK) that can be used to simulate CW keying, as if using a hand key. This command is used during factory alignment. It could also be used for on-air CW transmission, replacing the key or paddle. The software application would be responsible for ASCII to CW translation and/or could provide its own keying input device. HEADPHONES AND SPEAKERS The 3.5 mm PHONES jack accommodates headphones or an externally amplified speaker. A stereo plug must be used in all cases. If the log tray is installed on the same side as the headphone jack (which is the case for right-handed operators), a small-format, right-angle headphone plug will be needed to avoid interference with the log tray during operation. Headphones are preferred when wind or other noise sources are present. However, the KH1 does include a small internal speaker, located on the bottom panel, between the two knobs. When using the speaker, strong signals or high sidetone volume settings can cause a significant increase in average receive current drain. If this occurs, you can reduce AF gain or sidetone level. DISPLAY The KH1 uses an alphanumeric LCD with two lines of 16 characters. The display is backlit at all times, consuming only 6 mA of current while making the display easily readable under any lighting conditions. The KH1 FRONT PANEL QUICK REFERENCE (next page) shows the normal operating display. Subsequent sections show examples of all the different displays used. With most switch functions, the LCD is divided into four columns that correspond to the four push-button switches below it. In such cases, the upper line of the LCD shows switch tap functions, while the lower line shows hold functions. (This is presented in detail on pg. 16.) Small white and yellow squares to the left of the display and switches serve as a reminder of this relationship. -

{BFO} FL1 and FL2. This is not necessary for FL3, or for the filters used in SSB modes. CW: 9213.80 NOTE: BFO adjustment does not the affect actual receive frequency of the KH1, LSB: 9213.80 because the BFO is taken into account when the local oscillator frequency (LO) is USB: 9216.00 calculated. This means that as the BFO is changed, the pitch of received signals does not change, so the BFO can easily be adjusted for best signal amplitude. To align the BFO frequencies: • Put the KH1 into TX TEST mode to prevent possible damage to the signal generator due to accidental transmit. Use -> X M T R T S T • Connect a signal generator to the KH1’s BNC jack. Set the sig gen for any convenient test frequency, with amplitude of -90 dBm. • Select CW mode using the mode up/down functions ( -> ).

Above 10 MHz the same value can be used for all 100 kHz segments. Using the Audio Signal Strength Display: When the ADJ BPF menu entry is unlocked, line 1 of the LCD shows the relative audio signal level as a 5-digit number. For weak signals that don’t activate AGC, this can be used for BPF alignment in lieu of peaking the signal by ear. It also provides a way to measure the MDS of the KH1’s receiver, as follows. To measure receiver MDS: • Put the KH1 into TX TEST mode to prevent possible damage to the signal generator due to accidental transmit. Use -> X M T R T S T • Bypass the ATU, if applicable, using MENU:ATU MODE. • Select crystal filter 1 using -> . (Note: MDS may vary slightly among R C V R F L 1 the three filter bandwidths. FL1’s bandwidth is ~300-500 Hz.) •...
- Page 27 • Connect a dummy load to the BNC jack and a paddle key to the key jack. • Make sure MENU:KEY JACK is not set to RS232. • Set the whip band switch on the top panel to the center-OFF position (if applicable). This disconnects the whip toroid from the ATU, reducing stray reactance, and eliminates any RF burn hazard from the whip mounting bolt. • Set MENU:ATU MODE to Bypass, if applicable. • Calibrate the wattmeter using MENU:ADJ WMTR if not already completed. • Locate the ADJ PWR menu entry and unlock it. • Press the hand key or paddle (firmware treats paddles as hand keys while in this menu entry). This will put the radio into TX mode. Adjust the parameter using the VFO knob until the desired power output is obtained. ADJ REF Calibrates the synthesizer reference frequency. Once this is set on any band, all bands will be calibrated. This is factory-aligned to ~ +/- 20 Hz at 25 C. {REF} To calibrate the reference frequency: -0.40 kHz • Put the KH1 into TX TEST mode to prevent possible damage to the signal generator due to accidental transmit. Use -> X M T R T S T • Inject a signal at any convenient frequency (factory: 21.1 MHz). • Select CW mode and tune the VFO to that exact frequency. • Unlock ADJ REF. Set the parameter so that RX signal pitch matches sidetone.

- Page 29 ADJ WMTR Calibrates the KH1’s power reading against a known-accurate external watt meter. {WMT} To calibrate the watt meter: 100 • Connect a known-accurate wattmeter and 50 ohm dummy load to the BNC jack and a keyer paddle or hand key to the KEY/DATA jack. • Make sure MENU:KEY JACK is not set to RS232. • Set the whip band switch on the top panel to the center-OFF position (if applicable). This disconnects the whip toroid from the ATU, reducing stray reactance, and eliminates any RF burn hazard from the whip mounting bolt. • Set MENU:ATU MODE to Bypass, if applicable. • Locate the ADJ WMTR menu entry and unlock it. • Press the hand key or paddle (firmware configures the jack as a hand key on both the dot and dash inputs). This will put the radio into transmit mode. • Adjust the parameter until the KH1 reading matches the external watt meter. ATU MODE If an ATU is installed, set this parameter to Bypass or Auto. When set to Auto, an ATU icon will appear in line 2 of the operating display. If the parameter is set to {ATM} anything besides Not Inst., the KH1 will test the ATU module on power-up. Not Inst To use ATU MODE test settings: • The K1 - K8 Test settings activate individual latching relays. Firmware treats paddles as hand keys while in these test modes so SWR can be easily checked. This is useful for verifying the L and C components on the ATU. • The GP0 - GP7 Test settings also activate K1 - K8. But instead of returning to nominal voltage after activating a latching relay, they hold the associated driver output at 5 V. • The COM setting doesn’t activate relays; it places 5 V on the common line.
- Page 30 VBAT also shows approximate ampere-hours of energy consumed since the AH parameter was last reset to 0. (See MENU:VBAT for details). EE INIT CAUTION: This menu entry can be used to reinitialize ALL of the KH1’s stored parameters, or just the OPERATIONAL parameters. {EE} If a full EE INIT is done, factory calibration settings will be lost, so a full recalibration will be necessary. To avoid this, try an OPERATIONAL EE INIT first. Prior to doing an EE INIT of either type, you should save your full KH1 configuration use KH1 Utility. See CONFIGURATION LOAD/SAVE (pg. 23). Each KH1’s initial factory configuration is also saved and can be sent to you on request. EE INIT procedure: • Unlock the EE INIT menu entry. This is a safe operation that does not start init. • Set the parameter to OPERATIONAL or FULL. This is also safe, since EEPROM initialization does not take place until power is turned OFF and back ON. To cancel any pending init, set the parameter back to Disabled, then exit the menu. • To proceed with EE INIT, turn the KH1 OFF; wait a few seconds; turn it back ON. • When you see the message “INIT REQUIRED,” tap any switch. The selected EEPROM parameter initialization type will then occur. • If you unintentionally reset all parameters, contact Elecraft support. FIRMWARE Shows the firmware revision, e.g. 1.00. There will also be a note about the revision type to the right of the rev. number: “FT” = field test, “BETA” = beta test, and {F/W} “PROD” = production release. KEY IAMB Selects the Iambic keying mode (A or B). The default (mode A) is a little more forgiving for first-time operators. Mode B may be preferred by operators who {IAM} learned to do “squeeze-keying” with a keyer having a similar mode. Both provide MODE A dot- and dash-memories, but with slightly different “element-insert” timing.

The built- {LOG} in keyer must be used to allow firmware to decode the user’s transmitted CW. OFF To configure and use CW text logging: • To enable logging, set the parameter to ON. TX text decode will then be turned on, and the MODE icon will flash off every few seconds as a reminder. If the log is filled, LOG FULL will be displayed until you tap any switch. • Make sure MENU:ADJ DATE and MENU:ADJ TIME have been set up. • To erase all log data, set the parameter to ERASE, then exit the menu. • To scroll through logged text, set the parameter to VIEW. The LCD will then show time/date stamps, band, and mode on line 1, and text on line 2. Use the VFO knob to scroll through text. Tap/hold the VFO knob to change scroll rate. • To “dump” the log as text, send “LG;” to the KH1 using KH1 Utility’s Command Tester screen. The text can then be manually processed or copied/pasted into a third-party application for automatic extraction (not provided by Elecraft). MSG RPT Sets the message repeat interval. To repeat a message, hold a message function (M1 – M3 or M4 – M6) rather than tap. A 5 - 6 sec. interval is about right for {RPT} casual CQing. Shorter intervals may be needed during contests, and longer for 5 sec periodic CW beacons. During the pause between repeated messages, a letter r appears to the right of the mode character (C). PAN MODE Turns the scan/mini-pan function on or off. See pg. 19. {PAN} Off PAN SPAN Sets the total frequency range for the scan/mini-pan function. See pg. 19.
- Page 32 PFn FUNC Configures the KH1’s user-programmable functions as shortcuts to any menu entry. {PFn} Programmable function setup and use: PFn Unset • Locate the menu entry for the target PFn function (e.g. PF1 FUNC). • Rotate VFO A to select the desired menu entry (e.g. ATU MODE). • This will change the function’s text to a 3-letter abbreviation that serves as a reminder of the assignment (in this case, ATM). • Exit the menu. The target PFn function (in this case, -> ) will P F n / X M T R A T M now jump to the specified menu entry (ATU MODE). • If a menu entry is “binary” (2-valued), accessing it via a PFn function will change the value, display it, then return to normal display. In a few cases this applies to menu entries with more than two values. For example, if ATU MODE is set to Bypass or Auto, it will act like a 2-valued menu entry for PFn purposes. • To clear a PFn assignment, set the PFn FUNC parameter to the value PFn Unset by scrolling the parameter to the name of the PFn FUNC entry itself. RIT CLEAR This menu entry can only be used as a PFn assignment. That function, when accessed, will clear any RIT/XIT offset.

• Internal speaker clipping / distortion: The KH1’s small internal speaker is not intended for use in high-noise environments, such as in a noisy vehicle or outdoors in high winds. If audible artifacts occur, reduce AF gain or switch to headphones (or use an external powered speaker). • No received signal, or signal too low: Check all of the following: (1) antenna connectors; (2) attenuator setting; (3) AF gain setting; (4) whip slide switch setting (may be in center-off position); (5) headphone plug. • Audio noise drops briefly after large QSY: The synthesizer IC used in the KH1 does internal recalibration after the VFO moves a certain distance (50-150 kHz). This brief transition may be perceived as a short audio dropout. • Opposite-sideband images heard: Some received opposite-sideband (OSB) signal will always be heard on strong signals with a 4-crystal filter. The amount varies with filter bandwidth; suppression will be best with setting FL1. With strong signals, AGC reduces their audio level when tuned in, but not when tuned to the OSB image, reducing apparent OSB suppression. • Mobile installation noise: If the 12 V DC accessory jack in a vehicle causes interference to the KH1’s receiver: (1) improve vehicle’s DC filtering; (2) use a battery; (3) relocate the antenna. • HI RFI warning: The KH1 protects itself from high signal levels. First the -10 dB attenuator is inserted (if attenuation was set to 0 dB). The second step, if necessary, is to insert the -30 dB attenuator. Once signals return to a safe level for 5 seconds, the attenuator will be turned off.

Page 37: Theory Of Operation
THEORY OF OPERATION Receiver The KH1’s receiver uses a low-current superhet architecture with a 9.215 MHz I.F. This frequency provides a good balance between crystal filter performance and image rejection. The mixer’s noise figure is low enough to preclude the use of an RF preamp. A two-stage RF attenuator is provided for strong-signal situations. Local oscillator signals for both the LO and BFO are synthesized by a specialized IC that generates signals in the GHz range, then divides them down to HF. This provides both fine resolution and low phase noise. High-side mixer injection (above the low-pass filter cutoff) is used on all five bands (40-15 m), again for the purpose of improving image rejection. Audio-derived AGC is developed out of the AF preamp stage, then DC-amplified by a darlington transistor. The resulting voltage is applied to pin 1 of both the mixer and product detector, resulting in a very usable AGC range. The class-AB final audio amp stage uses analog electronic gain control so it can be adjusted by the MCU. The gain control voltage is generated by a DAC (D-to-A converter) channel. The amp can drive the small speaker to about 0.5 W peak. Transmitter The same IC that generates receive LO and BFO also generates the TX carrier frequency during transmit. This is amplified by an NPN driver stage, then fed to a VHF MOSFET TO-220 package transistor biased class AB to ensure good gain and power output from 7 to 15 MHz. Power output is controlled by driver bias. The driver’s keying output wave shape is generated by a PNP high-side integrator to prevent key clicks. Low-pass filter and ATU relays are latching to reduce total current drain. Control circuits and signal processing All transceiver control functions are controlled by a PIC18 microcontroller. The MCU also handles signal some processing functions: (1) sidetone generation; (2) CW text decode; (3) spectral analysis to drive the mini-pan display; (4) audio signal detection and averaging, for the S-meter and other purposes. TR switching is handled by a MOSFET switch. Supplemental circuits include voltage, current and temperature monitoring; a 32 K EEPROM for decoded TX text logging; and a real-time clock IC (RTC). -
