When in Data Mode PSK-D (31 bps) I get SPL N/A when trying to operate split. Both VFO's were on the same frequency but could not get VFO B to go up. What do I need to do to go into split operation in this mode? Today VK0TH was operating on 28,121 MHz and listening 400 Hz up. I just could not get into split mode. 73, Bud W3LL w3ll at arrl.net
