[hpsdr] MUNIN low output

[Kjell Karlsen]

Hi Don

Just a stupid question: Do you use the Gain By Band in PSDR to set the  
output from Hermes to drive Munin?

On all the units I have built, I can get >100W linear power out on all  
bands except on 6 meter were it may go down to 80-90W.

The gain in Munin is falling on the higher frequencies so the Gain By Band  
settings may be from 55 dB on the lower bands to 46 dB on 10 meter and 42  
on 6 meter.

Be sure that the DRIVE is at 100% all the time when you test!

73, Kjell
