N1MM Remote CW Sidetone - one solution

Mike-VA3MW Administrator, FlexRadio Employee, Community Manager, Super Elmer, Moderator admin

I wanted to thank WD8KNC, George, for this cool CW solution.

His 'sidetone' program is installed on the PC running N1MM and SmartSDR CAT to product a local CW sidetone when N1MM is sending CW to the radio via the SmartSDR CAT WinKeyer emulator.

You can find the software on his webpage here: http://ghafler.com/download.html?returnurl=wd8knc.html&vid=X324810 and scroll down the page.

The current version looks a bit different.

This is the overview of how it looks if you think like a WinKeyer command:

You will also need to find a VSP Pair (Virtual Serial Port) program. There are many such as com0com, etc. Others may share what they use and what works for them.

However, it looks like this in Windows Control Panel. Your numbers (COM29 / COM30) may be different numbers and make sure the numbers do not conflict with any other number. All numbers have to be unique.

This is my setup as part of my example:

This means you can send data to COM29 and it will come out on COM30.

For N1MM, we want to setup the CW / WinKeyer port to COM29:

On George's software, the Virtual port is the 'exit' port from the VSP pair. In this case 30. "Side Tone" hears the command sent by N1MM, produces the CW Audio and then sends it on to the radio via SmartSDR CAT.

WinKey port is the same as the SmartSDR WinKeyer port you created at some point.

Once, that is done (and you see 2 green 'LEDs' on the software, test your solution by sending CW from N1MM and see if it all works as you want it to.

There is no reason why George's program should not work with other logging programs as well that uses a WinKeyer command set.

    Thanks George and Mike this works great and was just what I was looking for for contesting using just my laptop remotely! Has anyone got this working with com0com or another free VSP software? I could only get it to work with the "Electronics Team" VSP and I'm not sure what's different about that compared to other VSP software.
    Thanks again

    I think I had it working with Com0Com.

    Here I have a pair called 33 and 34.

    One more option is WKFlex 2.0 which is now fully integrated with N1MM.
