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?
https://www.radioreference.com/apps/db/?siteId=22010

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....
