Heltec v4.2 Repeater POOR RX / Deaf

[theinfguy]

Heltec v4.2 boards flashed with repeater FW (Either main 1.14.0, 1.14.1 or nightly dev 1.14.1) appear to suffer extremely poor RX when compared to a v3 or a v4.3 (with new dev FW).

Its so bad, that my repeaters are missing and not repeating packets which are received by my v3 companion node in exactly the same place. 95%+ miss rate. They are essentially deaf to the world.

I have checked with rx gain both on and off, this has no effect.

I see there are various posts and pulls about related issues with the 4.2, but think this needs a single issue raising.

I have a couple of them deployed and having no issues with sensitivity. What is your agc.reset.interval set to? Maybe they get stuck at -120 dB.

What firmware are you running? And what should the agc.reset.interval be? I have reflashed/erased several times.

1.14.1. Try setting it to 4 and see if anything changes.
