Split tuning on VFOB Question

Post by K1VP »

I have a Flex 1500 and have a question regarding split operation. With other radios I have operated split by listening to the desired station on VFO A and switching to VFO B to listen for responding stations and/or finding open slots. Once I know where to call, I return to listening on VFO A. In PowerSDR with the Flex 1500 it seems I can only listen using VFO A and can only use the Flex Control knob to tune VFO A. By using the "A><B" button I can reverse the VFO A and VFO B which enables me to listen/tune VFO B. I then need to hit it again to get back to transmitting on split freq.

Is this the procedure for working split in PowerSDR or have I not found the setting to be able to listen/tune VFO B?

thank you.

Thats XFC option.

If your in SPLT mode (button is RED), then you can click the MultiRX button (turns green) to listen to VFOB

Right click on the SPLT button, it will toggle between +/- 5khz phone and +/- 1khz CW automatically

Setup->Display->Split TX Listen checkbox is so when you Right click on the SPLT button, it will automatically turn on MultiRX
then you can click on MultiRX button to manually turn off the XFC
