I'm not aware of a master gain parameter. LNA, MIX, IF are the three gain
controls. All take value between 0-15.

Trying to test out an AIRSPY R2 and the signal level v. an RTL is not
even close.
I've got -N options for LNA, MIX, IF, but what is the option for the
MASTER GAIN?
I've tried MAS, MASTER in the -N option, no change in the signal.
I've tried -g as well no joy.
Example:
./rx.py --args 'airspy' -N 'MASTER:50,IF:10,MIX:5,LNA:50' -S 2500000
-f 769.55625e6 -v 7 -T P25PC.tsv -q 2 -V -2 -U -x 2 2>> airspy.log
./rx.py --args 'airspy' -N 'IF:10,MIX:5,LNA:15' -S 2500000 -f
774.55625e6 -v 7 -T P25PC.tsv -q 2 -V -2 -U -x 2 2>> airspy.log
What is the CORRECT method to set the MASTER GAIN of the Airspys,
using something else its set to 14 for a good signal.
Thanks.
