RXA - receive audio,

ground.
These are commonly available pins found on nearly ALL radios, HF and VHF.
The most common connection from the KAM’98 will be to the microphone jack
(on the front of the radio) for transmitting, and to the external speaker jack (on
the back of the radio) for receiving. The manual for the radio will show the mi

crophone jack wiring information.
All manufacturers use different names for the functions of the pins on the mic
jack. Some radios may have a dedicated connector just for connection to an ex-
ternal modem, usually called a DATA jack. Here are some examples of the differ-
ent pin names, and the KAM ’98 pin to which they would be connected:
• connected on the mic jack
• mic or mic audio, modulation, modulator input, or TX audio, would
be connected to the TXA (transmit audio) pin on the KAM ’98.
•
PTT(push to talk), SEND, or standby, would be connected to the PTT
pin on the KAM’’98.
•
Ground or PTT ground, would be connected to the ground pin on the
KAM ’98.
•
connected to the external speaker jack
•
Connect the RXA(receive audio) pin on the KAM’’98 to the tip of the
external speaker plug on the radio. Some radios may have a connec
-
tion in the mic jack for receive audio, and may be called RX audio,
RD, AF, or AF out, and would be connected to the KAM’98 instead
of the radios external speaker connection.
In the case of connecting to a dedicated DATA jack on the radio:
•
DATA IN, packet DATA input, or TX DATA, would connect to the TXA
pin on the KAM’98.
•
DATA OUT, RX DATA, or 1200bps RX audio, would be connected to
the RXA pin on the KAM’98.
