Mr. Tom Rondeau,
Thank you for the info. Yes, I thought of controlling the airspy by the
source-block parameters. But, reading this URL.
http://sdr.osmocom.org/trac/wiki/GrOsmoSDR
Airspy explanation is like this.
AirSpy? Source
airspy Use this argument without a value
bias=1|0 Enable or disable DC bias at the antenna input
So there seems no parameter for choosing 1 device from 2 (or more).
How can we control? I want to know this point...
Regards,
Mamoru Yamamoto
