[hpsdr] status hpSDR mic level

[a.groff]

It looks to me like the TX mic level meter in PSDR is not operation 
correctly...
Operating in the linear range, with processing off, a 10db change in mic 
input level, will cause a 10db change on the TX panadapter and external 
power output but only a 3db change on the mic TX meter....
The MIC TX meter in the HPSDR version of PSDR seems to be scaled 
differently than the current Flex versions.

Pentalope itself appears to be fine...

I use Mic Gain of 25 to 30 to get in the TX Meter Mic a 0 dB reading 
when speaking. Panadapter then shows a noise level of about -50 dBm/bin 
which is comparable with what I get with the FLEX.

of < -30 in case of the FLEX. I will do spectral output power density 
measurements in the next days.
