For optimum operation of microKEYER II, the audio levels must be set properly. The function of each control
was described in the AUDIO MIXER and DVK sections of the manual. Following a step-by-step approach will
help you to set proper levels.
Configuring micro KEYER II for your radio:
1. Connect the original microphone for your transceiver directly to the mic input of the transceiver.
2. Connect the transceiver to a dummy load and set it to USB or LSB.
3. Turn off any speech processor, key the radio, talk into the mic and while watching the ALC indication
rotate the transceiver Mic Gain so that the ALC peaks at the top of the ALC zone.
Do not adjust the Mic Gain again.
4. Disconnect the microphone from from your transceiver and attach the mic cable from MK II.
5. Open the cover of microKEYER II and check the position of the jumpers for the microphones.
6. Set the three trimmers (located just to the front of the RADIO
DB37) to the middle of their range.
7. Connect the radio mic to the RJ-45 connector and select the
"Rear" mic on the Audio Switching tab. Set both VOICE and
FSK/DIGITAL to "Microphone jack".
8. Key the transceiver, speak into the radio microphone and adjust the MIC (center) trimmer so that the
transceiver ALC peaks at the top of the ALC zone.
9. Disconnect the radio mic from the RJ-45 connector. Connect your headset or boom microphone to the
EXT MIC jack and select the "Front" mic on the Audio Switching tab.
10. Put the transceiver into transmit, speak into the microphone and adjust the EXT MIC (left) trimmer so that
the transceiver ALC peaks at the top of the ALC zone (same as step 9).
