Failed eSSB transmit audio.

I have put together the tools I need for eSSB on my 6400 (with the exception of the one between my ears). I managed to get the 6400 up and running via direct contact, i.e. audio out, stock mic and PTT. To start, I put together all the hardware for eSSB, but found it took up too much real estate.

So I built a real nifty PC, way more horse power than I need, UMC1820 for any audio input/output and loaded software to essentially do the work of the hardware. Now with only cat5 and a PTT trigger. I managed to get the meter to register in SSDR.

Here's the rub. When I hit the PTT via trigger, i see the radio is transmitting but with no audio fluctuation in the outgoing signal.

For me this is harder to troubleshoot than the weapon system on a B-52E (the old days). Can anyone, with experience with this issue help.

    You will need to hit PTT within the SmartSDR client, not the back of the radio if you wish to use PC Audio for you SSB transmit stream.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
