2. Observe the radio to determine if it is being switched to the “Transmit” con
-
dition. If not, recheck wiring between the KAM’98 radio port, PTT pin, and
ground on the microphone jack.
3. Set the CD command to INTERNAL and turn the radio squelch control to
“OFF” and see if the RCV LED illuminates on the packet controller. If it
does not light, recheck the audio connection between your transceiver and
the KAM’98.
4. If possible, monitor your transmitted signal with another radio. If the trans
-
mitter is keying to “Transmit” but weak or no audio is monitored, increase
AFSK output as necessary by increasing the XMITLVL parameter value for
this port. (See the XMITLVL parameter in the command reference for de-
tails).
Cannot Transmit
1. Check the XMITOK command – it must be ON to allow transmitting.
2. If using a “fixed level” (i.e., the RCV LED stays on all the time) Receive Au-
dio from the radio, which the volume and squelch do not change, set the CD
parameter to SOFTWARE.
Cannot Return to Command Mode
1. The single most common cause of this is that the STOP character (and usu
-
ally XOFF) have been inadvertently set to the same as the COMMAND char
-
acter. This is usually caused by the use of the dollar sign ($) as a
streamswitch. If you use the $, be aware that you cannot enter hex values
without PASSing the dollar sign. Symptoms for this usually are that you can
talk to the KAM’98 fine in Command Mode, you can usually talk to others
on the air, but you just can’t get back to Command Mode. With most PC ter
-
minal programs, pressing <Ctrl+C> will display the heart character, but you
still don’t get the cmd: prompt.
