Re: [Discuss-gnuradio] Airspy: multiple boards available with GNU Radio?

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
