I interfaced my TNC to TR-Log (6.74), and I can't get Ctrl-U to work like it says in the book. Packet seems to work fine, I can connect and do regular packet things in the Ctrl-B window, and the spots appear in the bandmap as they should. However, Ctrl-U does nothing ... bandmap on or bandmap off. Any ideas? 73, Fred, K6DGW Auburn CA
