VFO B "FB;" & "FT;" do not work when split is initiated via SmartSDR GUI

n3oc

Hi I am new to Flex, so maybe I don't understand this correctly. But I did search and looks like this issue has come up before, so I think it is valid.

I understand there is no true VFO B. I get it.

CAT does not report VFO B frequency or split unless split is initiated from CAT with FT1;

If you initiate the exact same spit scenario from the GUI, by pressing the split button, FB; does not work. It will only work if you initiate split from CAT.

This is a problem for those of us with solid-state amps that absolutely must know the transmit freq for every PTT or risk blowing the amp because the tuner is not informed of the correct tx freq.

N1MM does not see split either, unless it initiated the split. Then VFO B can be read and split is fine, and can be toggled on and off.

But if you do it strictly from the SmartSDR GUI, all the devices dependent on CAT are blind to this tx freq change.

I hope I am just doing something wrong, but I don't think so.

Rig is 6400 and firmware and SmartSDR are 4.1.5

Has this always been this way, or is this something new/bug in 4.1.5? Or am I missing something to initiate proper split just from the GUI, I am just pressing SPLIT and the GUI looks exactly the same as if CAT sent FT1;

thanks!
