Maestro DEXP Greyed Out

I've noticed DEXP is greyed out / not available on my Maestro for M-MIC1, M-MIC2, M-LINE but available R-MIC, R-BAL and R-ACC?? The manual makes no mention of DEXP not working on the Maestro?? Am I doing something wrong? I'm using a default Radiosport Mic Profile...

The DEXP function is a hardware function that is availabe in the radio but not available in the Maestro hardware ( or in the PC with a PC mic).

Bob you are absolutely correct! Another disappointment to me. It will be hard to use the Maestro in a crowded space like a DX expedition or multi op contest! Too much background noise....

While this is a bummer if you were in a multi op or dx situation you can always plug right into the radio.
The point here is to use the Maestro REMOTELY, a use that has proven unsatisfactory for this reason.
