Happy days!!!
I accomplished something I should have done months ago before going through all my "transmit antenna switch/spend hundreds on protecting the RSPdx" gyrations.
I successfully interconnected the Win4Icom Suite with the SDRplay software and my IC-7100 transceiver.
The panadapter that is part of the Win4Icom Suite is now tied into the radio without any antenna that is connected to the radio also connected to the RSPdx. So no protective TX relay switch is required and it "appears" I've accomplished the same thing. The Win4Icom waterfall moves with changing frequencies on the radio, etc.
No antenna that is connected to the IC-7100 is also connected to the RSPdx. The SDRplay app isn't even open on my computer.
I DO have RF suppressors connected to the antenna inputs of the RSPdx just as a precaution against outdoor antenna interactions.
I have apparently been wasting my time trying to find a way to protect the RSPdx while transmitting from the IC-7100 with the RSPdx connected to the same antenna as the IC-7100.
All that is unnecessary. The Win4Icom accomplishes everything I wanted to accomplish without an RF interconnection that would possibly stress or destroy the front end of the RSPdx - for a fraction of the cost!
If my observations and assumptions are correct, Happy Days!!!
If anyone asked me how I got all this to work, I would be at a loss without spending a few hours going back to figure it out again. Apparently it was easier than I thought or it wouldn't have happened.
