Thanks much. I think I was confusing (or was confused by) the way the
Radio Reference database provided the site information. The statewide
network number is 0x343, but there's also an individual site ID (0x25A).
I mistakenly took the site ID as the NAC. Easy to fix.
You're talking about LSM, which I don't recognize. The modulation
options appear to be C4FM and CQPSK. I assume that LSM == CQPSK?
I'll play around with these suggestions later today. Thanks!

ok the console window indicates you're receiving

whereas the traffic tab shows a NAC of 0x25A. (with respect to these
two NACs, your trunk.tsv is totally daft). This is certainly one
problem. At the stage you're at you should forego the trunk TSV and use
manual mode until the trunk CC is properly acquired.
Separately the datascope indicates a very strong LSM signal (i.e., not
C4FM), so you'll need to use the constellation tab for normal ops. If
you stay on the datascope tab it will (incorrectly) use the C4FM demod,
this is a legacy of scope.py. Based on that constellation any attempt
to use C4FM will fail miserably, it's pretty nasty and a really good
example of why C4FM demods won't work well on LSM.
One other thing is that your datacscope tab isn't centered vertically,
it suggests the tuning is slightly below where it should be tuned. This
can be adjusted using the -q pa rameter and fine tuned using the slider...
