IC7300 permanent TXproblem

[G3RIR]

I have no problems with my IC7610 or with my IC9700 but as soon as I select my IC7300 it goes to TX.

This does not happen with N1MM which I use for contesting nor with DXLAB nor with Logger32. I don't want to continue with Logger32 as it does not allow more than 2 radios. DXLAB allows up to 4 radios but I find the user interface not easy. I am trying Winlog32 to see how I get on with it.

So clues please as what setting I have wrong somewhere.

I have found a clue by experiment. In the settings for the 7300 in winlog32 I had RTS set on. Settings this off cures the problem. But I have RTS on set for my 7610 and for my 9700 with no problem.

Must be closing in on the problem but not quite there

Hi Neil,

You probably have enabled the USB SEND RTS for PTT in the IC-7300 CI-V settings menu, so the PTT is triggered when the RTS line is set to high.
