Using MRP40 to monitor CW Sending?

W2ECK Member ✭✭
edited November 2021 in Third-Party Software
I'd like to use MRP40 or some other program,  to monitor my CW sending. In other words decode what I am sending. Was able to do this with previous radio but haven't figured out how to do with my new 6600. Any ideas on how this can be done?

    Any update on this Paul? Did you get the MRP40 integrated with your Flex radio? @W2ECK

    Yes, I was able to get MRP40 to monitor my CW sending. I installed a splitter cable in the phone jack on my 6600. One leg of the splitter goes to my phones and the other leg goes to the "Line In" jack on my win 10 PC Sound card ( add on sound card- but should work with embedded sound card also)

    So then in MRP40 - Options - Show Sound card- Select RX Sound card- I have picked Line IN ( Sound Blaster Audigy) . I have a Sound Blaster card but you should see Line In & what sound card you have.

    BTW: this same set up works for other Programs. I have tried it with CWGet and CW Decoder. Of the three, I prefer CW Decoder.

    I have found having CW Decoder open when practicing sending has helped my accuracy and spacing a great deal.

    Hope this helps

    Why are you not using DAX? It is designed for exactly this purpose: to provide audio in/out from the Flex to other applications that require audio. Examples: WSJT-X, CW decoders, or RTTY programs like MMTTY. On your CW decoder, select the proper DAX receive channel...

    Because, at least for me, it doesn't work.

    If I use DAXAudio RX 1 or whatever RX # applicable, these programs will decode received CW, but not my sent CW. DAX Reserved Audio TX will not decode my sending, which is my main purpose of doing this.

    So if you have got Decoding the sent side to work, maybe I am doing something wrong. Please let me know your setup.

    Got a notification that Mike VA3MW had commented on this thread, but can't find his input.

    Yes, my error. For some reason, Flex does not make the transmitted CW monitor available to DAX. It would certainly be nice if they did, wouldn't it?

    Your solution is probably the only way right now.

    @Craig_KØCF I believe you are right - CW is not available in DAX. There are threads here in the flexradio community documenting this feature request since 2014. The only solution that seems to work is to use the audio splitter- one leg to your headphones, the other into the line in on your PC audio sound card.

    The CW Monitor Audio is not available via DAX.

    What you can do is run a physical cable from the device that you get CW audio from (radio, Maestro, etc) into the PC Line in and then have your CW program decode that audio stream.
