[drats_users] D-Rats Slow Data is Garbled - Packet doesn't decode

[Gerard Hickey]

Check the speed you are running the port at. If I remember correctly the IC-2820 runs at 9600 baud. I had the same problem with a IC-92. I was trying to run it at 9600 when it wanted 38400. At that time it was corrupt data also. Good luck.

I'm viewing the raw message data via remote and local PC connections hitting the RX radios and the packet is garbled.

It's seen both mobile and base usage and in all other ways appears to operate normally except for the data packets being garbled out to the other radios on D-Rats.  This is the first time I've tried to operate it via the D-Rats software.

Both the other radios hear and see the packet coming from the 2820 but can't decode it.  Because they can't decode the packet, the other radios don't see the 2820 station, but the 2820 can hear and see the D-Rats radios I'm testing with...it responds to ping and position requests but the 2820 packet in response is garbled and shows up as yellow highlighted raw text on the good testing radios.
