After update from 4.1.7 to 4.2.1 HS does not hear my radio TX

Post by KV4YQ »

I am using a RPi Zero 2W and I have updated my HS_Hat to 1.6.1 and have imaged the SD card at 4.2.1 . Everything seems normal but my hotspot no longer sees my radio transmit at all. I can pick up DMR traffic just fine on my static channels, but I can not reply. Zero reaction on the hotspot to my HT transmitter. Any ideas?

I found the problem was a large offset needed on the hotspot receiver. -400 This kept the hot spot from decoding at all. Use calibrate function.

400Hz is not a large offset, other similar devices sometimes are over 1.5kHz off frequency.
