PROBLEM:
When sending to a remote station using RMS Express (WinLink/Winmor), the software appears to be using audio picked up by the rig's microphone rather than audio delivered into the RigBlaster's LINE IN from the computer's LINE OUT.
While this is functional, it requires that the microphone be placed close to the station speakers so that it can hear what is being generated for an output.
I am pretty sure this is not the way it is designed.
Now, when using RTTY, PSK31, or other modes with MixW Version 2.2, all is fine, i.e., the RigBlaster feeds computer audio directly to the rig rather than through the microphone.
SETUP:
a. ICOM 756PRO
b. RigBlaster PRO configured to take RCV AUDIO from the mic connector using jumpers on P1 (irrelevant but listed for the sake of completeness).
c. Computer Windows 7 using internal sound card.
OPINION:
I assume that RigBlaster has a relay or switch internally to switch rig input audio away from microphone audio over to computer audio. Works fine with MixW but it seems that the command to cause this to happen is, somehow, not being issued by RMS Express.
SOLUTION:
The West Mountain Radio folks provided a quick solution. The basic answer was:
The Pro does indeed mute the microphone during PTT cycles, however, if you are using PTT by CAT the RIGblaster has no way of knowing that PTT has happened.... make sure that RMS Express is set to perform hardware PTT on the serial port using RTS (not via CAT). You can tell when you have it correctly configured as the red "ptt" LED will light on the RIGblaster.

After some fussing around and a couple of more emails, he provided the screenshot that shows how RMS Express must be set up. Simple, sweet, and it worked. Thanks to K7TMG and the West Mountain Radio folks for a quick solution.
