Re: [IRCA] Testing New SDR software

["Mark Durenberger" <Mark4@xxxxxxxxxxxxxxx>]

Mike (turns out we're neighbors):  I have been using the Perseus SDR for 
about a year; primarily for MW reception.  Doing a monthly column for a 
newsmagazine for the Blind which features station IDs from given areas.

The Perseus allows me to capture the entire broadcast band at one time, to 
sort it out later for presentation.

The REALLY cool thing is that one can experiment with antennas while 
watching the effect on the entire band at once.  So if an antenna is tunable 
you can quickly see how it favors one segment of the spectrum over another.

And the audio demodulation and filtering is excellent.

Best investment in receiving gear that I've ever made.

Regards,

Mark Durenberger
