Keyer Interface is not working with my IC-7300

[PA3ETM]

I would like some support for setting the CW function. I have already read a lot, but somewhere something is not quite right.
What did I do:

* My Log4OM is connected to my IC-7300 on the PC with Omnirig with 115200 baudrate on COM3
* The CI-V is connected and LOG4OM works fine
* The drivers for the IC-7300 are loaded
* My paddle is plugged in and works fine on my IC-7300 (BKIN is on)
* For Log4OM I use a USB printer cable shielded with 2x ferrite

From another source, I heard that I have to choose a 2nd port to work with CW Keyer. When I look in my PC I only see COM1 and COM3 so that does not work and it does not accept COM3 because it is already in use for Log4OM itself. For this I bought a 2nd USB cable CT-17 CI-V / CAT Cable and plugged it into the back of the 7300 (CI-V Remote Control Jack). Now I have an extra port (COM7 CH343 Serial)

Now I don't know whether in the settings | CW Keyer Interface, which option I should take. (Nothing / Winkeyer / TCIProtocol or Serial. I have tried all options but I can't get my 7300 to transmit

What I have noticed is that when I put the audio from my PC on speakers, I do hear the CW that I type in via CW Keyer or use the function keys

As far as I can tell now, the CW Keyer program does provide the correct information, but my 7300 does nothing with it

Well, it's quite a story and I hope you can give me the latest information.

Thanks in advance | Fred PA3ETM

As I stated when I answered your question on social media I do not have an Icom 7300 to test with!

The least expensive and most certain way to get it working is to use com port keying, using a cable from a PC USB port to the key socket on the 7300

I reccomend the Technofix cable here https://shop.technofix.uk/cables/cw-mor ... o-isolator - Beware of ebay imitations

Or you could make one yourself following these instructions https://www.n1rwy.org/?p=384

Or purchase the excellent Winkeyer USB

My Icom 7100 does not support keing via the CAT cable so I use the Technofix cable above and its fine with Log4OM.

Both my SunSDR and Hermes Lite 2 use TCI for keying and they work fine with Log4OM

My Kenwood TS480 is connected with a Winkeyer USB device and that also works fine with Log4OM
