? Looks like D-RATS is trying to connect to the Hotspot on TCP 20003 and the Hotspot is only listening on UDP 20003.

? Any clues??? Any assistance would be greatly appreciated..

Doug,

?

The port 20003 is for the repeater software to talk to the hotspot.? You want to talk to the software "before" it does its work and passes the information on to the hotpot.? You want to connect to port 20011 or the port listed as "local port" in the settings for the GMSK repeater software.? That is what needs to be connected to DRATS to work properly.? Once you do that, you should get a good connection and the error message should go away.

?

Use port 20011, not port 20003. ?I posted a longer message explaining why, but haven't seen it come up here, yet.
