To connect to the remote ICOM 735, we use cw over the internet protocol. (cwoip)

I used my laptop and mumble to login into the cwoip,  iCW PRO SERVER,  located in California.

Once logged in, move into the ICOM 735 mumble channel to hear the ICOM HF receive audio.

To send CW remotely, this ICOM has an audio derived keying circuit listening for any cw audio tones that are sent over mumble by anyone in the mumble ICOM 735 channel.  very similar to this circuit:

I use FLdigi for qrq sending and at the same time can also use Morse Keyer's iambic software keyer by using the buttons on my wireless mouse just like an iambic paddle.

 Due to near zero low latency monitoring of the sidetone, made possible by BREAKAWAY LIVE's asio function and its own brand of virtual audio cables, the delay in hearing your own sidetone is small enough that it is easy to compensate for the timing difference.  In order to hear both the audio from MUMBLE and MORSE KEYER and FLdigi on the computer sound card,  I had to use separate left and right channels for the two BREAKAWAY PIPELINE, virtual audio cables that are used in this setup.   FLdigi and Morse Keyer send their audio to PIPELINE 1 and MUMBLE sends its audio to PIPELINE 2.

Using asio4all with BREAKAWAY LIVE, then enables both PIPELINES to send audio to the sound card output.   A stereo to mono adapter for headphones is all that is needed then to hear both channels in both ears.

Here are some screenshots of the BREAKAWAY SETTINGS:
