Usually remembers to get the pointy end up
I put together a TRS/LCD earlier this year. It tested fine in initial testing. I tested it a few months later with charges, no problem. A few days ago I used it to fully test deployment in my assembled rocket - used it to split the rocket for drogue, and then for main, with no problem. But when I went to use it for an actual flight, I couldn't get it to sync. I don't see the LED(s) on the radio module blinking, so it doesn't seem as though it's trying - so I don't think its a 'wrong frequency' issue. Any tips on troubleshooting? This is the Ham version, if it matters.
