Watts of power output on the 144 MHz Amateur band and 40 Watts on the 430 MHz Ama- teur band. The high power output of the FT-7800R is produced by its RD70HVF1 Power MOS FET amplifier, with a direct-flow heat sink and thermostatically-controlled cooling fan maintain- ing a safe temperature for the transceiver’s circuitry.

Packet Interface Cable Availability of accessories may vary. Some accessories are supplied as standard per local requirements, while others may be unavailable in some regions. Consult your Yaesu dealer for details regarding these and any newly-available options Connection of any non-Yaesu- approved accessory, should it cause damage, may void the Limited Warranty on this appa- ratus.
Page 6: Installation
Do not install the transceiver on top of another heat-generating device (such as a power supply or amplifier), and do not place equipment, books, or papers on top of the FT-7800R. Avoid heating vents and window locations that could expose the transceiver to excessive direct sunlight, especially in hot climates.
Page 7: Safety Information
The FT-7800R is an electrical apparatus, as well as a generator of RF (Radio Frequency) energy, and you should exercise all safety precautions as are appropriate for this type of device. These safety tips apply to any device installed in a well-designed amateur radio station.
Page 8: Antenna Considerations
NTENNA ONSIDERATIONS The FT-7800R is designed for use with antennas presenting an impedance of near 50 Ohms at all operating frequencies. The antenna (or a 50 Ohm dummy load) should be connected whenever the transceiver is turned on, to avoid damage that could otherwise result if trans- mission occurs accidentally without an antenna.
Page 9 The use of the shortest possible length of the highest quality coaxial cable that fits within your budget will ensure the best performance from your FT-7800R. FT-7800R O...
Page 10: Mobile Installation
NSTALLATION OBILE NSTALLATION The FT-7800R must only be installed in vehicles having a 13.8 Volt negative ground elec- trical system. Mount the transceiver where the display, controls, and microphone are easily accessible, using the supplied MMB-36 mounting bracket. The transceiver may be installed in almost any location, but should not be positioned near a heating vent nor anywhere where it might interfere with driving (either visually or mechani- cally).

TNC, if it is designed for multiple-radio use, by connecting the TNC “Radio 1” port to the 1200 bps lines on the FT-7800R, and the “Radio 2” port to the 9600 bps lines. The pin connections of the Data connector are shown below.
Page 13 Finally, note that the Menu (“Set”) mode allows you to set the Packet data rate (1200 or 9600 bps) independently for each band. If you have trouble getting your FT-7800R to respond correctly during packet operation, check to be certain that you do not have Menu #26 (PKT.SPD) set to the wrong data rate.

Page 22: Basic Operation
Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features of the FT-7800R. I know you’re anxious to get on the air, but I encourage you to read the “Operation” section of this manual as thoroughly as possible, so you’ll get the most out of this fantastic new transceiver.
Page 23: Frequency Navigation
1 ) Tuning Dial Rotating the DIAL knob allows tuning in the pre-programmed steps established for the VFO frequency. Clockwise rotation of the DIAL knob causes the FT-7800R to be tuned toward a higher frequency, while counter-clockwise rotation will lower the operating frequency.
Page 24: Transmission
Changing the Transmitter Power Level You can select from among a total of four transmit power levels on your FT-7800R. To change the power level, press the [ LOW ( ACC )] key to select one of four power settings. These power...

In order to prevent accidental frequency change or inadvertent transmission, various aspects of the FT-7800R’s keys may be locked out. The possible lockout combinations are: LK KEY: Just the front panel keys and microphone buttons are locked out (except for the PTT switch).
Page 26: Display Brightness
DVANCED The FT-7800R display illumination has been specially engineered to provide high visibility with minimal disruption of your “night vision” while you are driving. The brightness of the display is manually adjustable, using the following procedure: 1. Press and hold in the [ BAND ( SET )] key for 1/2 second to enter the Set mode.

Page 28: Repeater Operation
The FT-7800R includes a number of features which make repeater operation simple and enjoyable. Your FT-7800R has been configured, at the factory, for the repeater shifts customary in your country. While the 144 MHz shift will be 600 kHz; on 70 cm, the shift may be 1.6 MHz, 7.6 MHz, or 5 MHz (USA version).

Page 34: Regular Memory Channel Operation
EMORY PERATION The FT-7800R provides a wide variety of memory system resources. These include: “Regular” Memory Channels, which includes: 1000 “Standard” memory channels, numbered “000” through “999.” 5 Home channels, providing storage and quick recall of one prime frequency on each operating band.
Page 35: Memory Operation
This will not cause transmission; instead, it signals the microprocessor that a separate transmit frequency is being programmed into that memory register. Whenever you recall a memory which contains in- dependently-stored transmit and receive frequen- cies, the “ ” indication will appear in the display.

Page 42: Scanning
CANNING The FT-7800R allows you to scan just the memory channels, the entire operating band, or a portion of that band. It will halt on signals encountered, so you can talk to the station(s) on that frequency, if you like.
Page 43: Vfo Scanning
7. To cancel scanning, press the [ SCAN ( SEL )] key momentarily again (or press the microphone’s PTT key). 1) When you start scanning, the FT-7800R will be changing frequency in the upward direction. If you want to change direction of the scan while it is underway, rotate the DIAL knob one click in the opposite direction (in this case, one click counter- clockwise).

Preferential Memory Scan The FT-7800R also allows you to set up a “Preferential Scan List” of channels which you can “flag” within the memory system. These channels are designated by a “ ” icon when you have selected them, one by one, for the Preferential Scan List.
Page 46: Memory Bank Scan
This feature allows you to check a Weather Broadcast Memory Channel while operating on a VFO scan or Memory channel scan. When the Weather Alert Scan feature is engaged, the FT-7800R will check the Weather Broadcast Memory Channels for activity every five seconds while operating on a VFO scan or Memory channel scan.
