Adjusting Receive Volume
Toproperly adjust the receive volume on your VHF radio, first, turn on your computer, start
your terminal program and turn on the KAMPlus. Next, turn on your radio and open the
squelch control (fully counter-clockwise). Slowly turn the volume up until the RCV LED on
the KAM Plus just lights. Increase the volume control slightly from this point. Next, turn the

The final step in connecting your KAMPlus into your station is to make the cable from the
KAM Plus to your HF radio. In order to transmit and receive, you must connect the following
pins from the 8-pin DIN connector on the KAMPlus to the appropriate pins on your HF radio:
Pin 1Transmit audio (white wire) connects to the microphone input of your radio.
Pin 2 Ground (black wire) connects to the ground ofyour radio.
Pin 3 Push-to-Talk (brown wire) connects to the PTT or STBY connection on your radio.
Pin 6 Receive audio (pre-wired mini-plug) connects to the external speaker jack of
your radio.
If you want to operate CW,you must also connect Pin 4 from the KAM Plus to your CW Key
jack exactly as you would connect a straight key. (Ifyour radio has a built-in electronic keyer,
you must disable it.)
For FSK operation (ifyour radio supports it) you must connect Pin 5 from the KAMPlus to the
FSK input on your radio.
The actual connections to your radio will vary depending on the type ofradio you are using.
Please refer to the appropriate diagrams below for the proper wiring used for the most common
radios. These diagrams show the wiring for AFSK (not FSK) operation and do not show the CW
keying line. NOTE that this wiring may be used for Packet, RTTY,ASCII, AMTOR, and Pactor.
