Thanks guys for all the help and tip
My first time using UDP.
I was able to find what the PI address was in the RF2K-S. I think that was the hardest part learning how to do that.
Once I found my IP address.. entered it in the Network Services in Command, and matched up the port address, Boob! There it is. I am hard wired to my router by the way.. So amp to router with an ethernet cable. I dont know how Commander finds my router.. over my pay scale...
Tnx Dave for the best software in ham radio!
