Hi

I would assume the
sensitivity would have a proper default for
normal speaker voltage. I tried different
volume settings with and without squelch.

Hello Chris,
pi@PiGate:~ $ sudo
listen -8ar
tnc: fm KA4UPC to
KJ4RUS-10 ctl SABM+ 23:30:12.301181
tnc: fm KA4UPC to
KJ4RUS-10 ctl DISC+ 23:30:32.274964
pi@PiGate:~ $ sudo
listen -8ar
^Cpi@PiGate:~ $ sudo
listen -8ar
tnc: fm KA4UPC to
KJ4RUS-10 ctl SABM+ 23:32:57.421067
tnc: fm KA4UPC to
KJ4RUS-10 ctl DISC+ 23:33:17.051743
Both of these look wrong as there aren't any
retries on the connection attempts.
pi@PiGate:~ $ sudo
listen -8ar
tnc: fm KA4UPC to
KJ4RUS-10 ctl SABM+ 23:33:38.938783
tnc: fm KA4UPC to

This looks more like what I would expect but
it's still not showing the expected connection
retry attempt at 22:33:58 timestamp.? Very
strange.? Regardless, your station is also not
decoding any responses from the remote station
so if you're confident the remote side is
responding with a clear strong signal, there is
a receive issue on the TNC side.
This is what I
ordered, assembled and tested fron
WVCARC
I am using a TYT
radio and I made the mic, spkr, ptt
connections myself.
My #1 suspicion is your connection to the radio
and the cable.? You need to make sure you're
getting the audio from radio into the TNC as you
expect.? You might try connecting a scope or
even a soundcard microphone input to the correct
testpoint on the TNC9k6 to confirm the expected
audio is making it.? If not, check the plug
connection on the TYT (hopefully these radios
offer more reliable connections than the
almost-always-terrible Baofeng radios).? For the
audio output from your radio (I'm assuming your
using a TYT HT.. not a mobile), you'll need to
make sure the volume setting is fairly LOW as
it's far easier to decode weak signals than it
is to decode overdriven / distorted signals.
Next, have you confirmed the TNC's RX level
(think of this as the input microphone level
setting)?
??
There doesn't seem to be much built-in audio
level tuning support in the PI9k6 firmware so
you might have to determine these levels
externally using a scope or other method.
I am 12 miles from
one station and 15 from the other
(with roof antenna) but I drove to
within a mile of each (with mag
mount). I was careful to match
frequency on the radio (no CAT).
Since you're troubleshooting receive levels,
consider changing the frequency to your APRS
frequency (144.390 here in the US) so you can
hear more incoming 1200bps AFSK packets to tune
things sooner.
