I've been using a TenTec model 516, the so-called Argonaut 5 and the recommended Prolific USB/serial adapter. So, I use a com port setup for rig cat but set PTT for rig cat as well. I can also use a com port for PTT via the USB/Serial logic in the Prolific. I've logged several qsls with this setup.
So all seems ok except I'm not sure about split mode. facts: On my setup wsjtx split mode causes selected bands to get assigned frequencies consistently, with 2Khz spread between VFOA and VFOB for HF bands . If I select split mode on the rig as well only vfoa is changed during band selection. I get the concept of stacking two vfos with freq offsets side by side to get greater effective bandwidth but can't get past that point. Some questions: 1) My receive bandwidth knob gives me up to 3000hz for all HF bands.. Does this mean I might have as much as 5000Hz receive bandwidth if the split mode feature works (as I think it might) on my rig? 2) The wsjtx manual talks about 500Hz offsets for transmit with split enabled. Would somebody please elaborate on that as I don't follow precisely how it works? 3) Am I confusing conventional rig spit mode with the wsjt-x feature AKA spit mode? 4) Is rig cat planned to set USB mode? My programmer's manual shows this as accessible via an ascii string which uses a different command syntax than the other rig cat commands. The workaround for split is to manually set each vfo on each band to USB before launching wsjtx. Livable for now. 5) With wstx split enabled I select a jt9 freq of 3772 and send CQ. The rig generates RF out and the displayed frequency is 3772. Is that really happening or do I need to look at the rig RF/AF output with a scope to confirm? thanks in advance for your answers chuck kb1zmx
