I hit '1' to open a spectrum graph showing that I am tuned to the control channel on 470.025 but it's a little off, so I used the tune buttons (<>) to line it up(+400). My ppm is 0. I also opened the '5' mixer graph and the number is fluctuating between 0 and just over 100. But, I'm still seeing "tsbks 0" at the top. The entire line looks like this:

You could add '-d 400' to your rx.py command so you don't have to do
that next time.

What's in Trunk.tsv?

Is this the site you're trying to get?

If so, it appears that the NAC should be 0x370, but you have 0x734.
boatbod's code allows you to specify 0 (zero) for the NAC, and it'll
take the first one it decodes on the control channel.

You could also use '-v 3'  (or higher, instead of 0), and see what you
get in stderr.log....
