Hello,
I've been doing some over the air testing with distant stations on 40m with good results, including good connections at arqbw=200.
The station is sending ARIM beacons periodically, which are FEC frame transmissions using FECMODE 4FSK.500.50. I've noticed that about 5% of the time a series of "Parameter" errors appear in the ARDOP_2Win exception log after the FEC frames are transmitted.
See debug and exception log excerpts below for a typical example.
Submitted in case it's helpful,
Bob NW8L
