Installing microKEYER II consists of several steps:
1) prepare MK II to work with your radios
2) install microHAM USB Device Router (the control and interface software)
3) configure microHAM CODEC
4) configure Router
5) set audio levels
1. Turn off the radio and make the rear panel of microKEYER II accessible.
2. Plug the DB37M of the radio cable set into the RADIO connector on the rear panel of the MK II. Connect ALL
connectors from the cable set to the matching jacks on the rear panel of your transceiver.
3. If your transceiver has dual receivers (FT-1000D, FT-1000MP, FT-2000, FT-9000, Orion, IC-7800, K3, etc.)
connect the fixed level audio output from the second receiver to the SUB RX jack
4. Connect the station microphone to the RJ45 MIC jack. If your microphone has a Foster
(round) connector, use the adapter supplied with the cable set.
If the station microphone uses an electret element (most Icom radios), open
microKEYER II and place the Electret jumper located just in front of the three trimmers
in the center of the board on both pins.
5. If you use a second microphone, connect your headset or boom
microphone to the 3.5 mm EXT MIC jack on the front panel.If the
headset or boom microphone uses an Electret microphone (e.g, Heil iC
elements and many computer headsets), open MK II and move the
DYN-EL jumper located behind the EXT MIC jack to the EL position.
NOTE: an electret element must be connected to both the tip and ring
of the 3.5 mm STEREO plug. A mono plug will work only with
SN#900 and above, close jumper at IC position.
6. Connect your paddles to the PADDLE jack.
7. For Icom transceivers, open MK II and install the ICVOX jumper located behind the
PTT IN jack. Otherwise, connect your transceiver PTT Out (linear) to the PTT IN
jack using the supplies RCA to RCA cable.
8. If you use a foot switch, connect the foot switch to the FOOTSW jack.
9. If your transceiver is capable of supplying +13.8 V at 500 mA on its Accessory port, you
may install the DB37 Power jumper located in the right rear corner just in front of the
+13.5 V DC jack.
NOTE: DO NOT use the DB37 Power jumper with Yaesu transceivers of if the
Accessory power is less than 12 Volts when transmitting (Elecraft K3).
10. Connect a 12 to 16V DC supply to the DC 13.8V jack.
Be sure to observe the proper polarity.
11. Locate but
