Ok.. .with the Airspys hidden magic spell documented... Do the HackRF's need something more like that??? I've got: --args 'hackrf' -g 65 -f 412.34e6 -N 'RF:14,IF:32,BB:26' As the various gains etc.....Any thing more to make it work "correctly?" :) ;) :) ;) That would certainly help with some other tests I'd like to do with OP25 v. some other stuff... Thanks advance....

rx.py Airspy MASTER GAIN Setting option?????

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.
