As you know, I'm a genius.
I'm the genius who had psk31 working, who then dismantled and moved his shack and subsequently couldn't get it working again. Before the move I had failed miserably to get SIM31 working, ever.
Well, one shack move later, with a different computer, I got the operating part of SIM31 going: the CAT configuration will have to be manual, no simple selecting the model of rig just yet.... It might take me a while.....
The freeware prog runs. It decodes PSK31 and it allows me to switch from PSK31 to SIM31. Brilliant!!
If I could find another SIM31 OP, I might even try for a QSO.....
