It's all about the Software

Hello There may be other programs that use the port. It is released by disconnecting and reconnecting. An example of a program could be WSJTX. If PTT has been set via serial COM, even if it does not use the port to transmit data, it occupies it for PTT command via DTR or RTS. It's just an example, t...

Hello

I think a solution would be a program that emulates the CAT operation of a transceiver.
Extract the frequency from that emulator and use it further.

Happy New Year Denis,

I have an approximately similar interface (CP2102). I installed it on my computer now. I have Windows 7 64 bits. My driver is from 27.09.2017. If you want, I'll send you the archive via email or put it on Drive.

(Google translate) Hi Denis, What interface do you use? Maybe the output level is on 3V3 and not on 5V. The connection length between the interface and the radio is too long. CAT connector is ok? Try installing the interface and SDC on another computer and compare the results. Try new drivers. Succe...

Hi Ernst, You're right, I saw it in the video. As I use SDRConsole as RX-frontend, working a DX in split-mode is a bit odd, everytime you try to change your tx-Freq you loose the RX-frequency... Fast solution is to stop tracking External Radio when you working in Split Mode. Then you can use them se...

Hi Ernst, In the External Radio Options window you have two settings, 1 and 2 in my image. The first setting drive the transceiver and the second interrogates the transceiver. Personally, I think setting 2 should be unchecked. Another solution, I'm not sure, during split work you can disconnect Exte...

Not working. I give up.

Thank you for info. I will try in next few time.

When the radio transmissions move on the screen and the cursor remains in the center, optically, there is no reference system. When they are fixed and the cursor moves, they become a reference system. In a ham radio contest you will never know which stations you worked or not.

Hi Simon I managed to synchronize between the SDR Console and my transceiver. Theoretically it works ok. What I receive in SDR can also be heard in my transceiver. When you click on the screen, the transceiver moves to the correct frequency. But after several clicks I don't know how often I listened...
