Title: VHF SDR? Post by: Carl WA1KPD on October 25, 2009, 02:43:05 PM I have the RFSpace SDR IQ and really like it as I dod a fair amount of traveling.
Is anyone aware of a similar rcvr for VHF? I have been searching a bit on the web and found this: http://www.scannermaster.com/Remote_1_Single_Stream_Software_p/01-520860.htm (http://www.scannermaster.com/Remote_1_Single_Stream_Software_p/01-520860.htm) Anyone familiar with it? I do have an IC-820 that would serve my needs if I could remotely control it. Thanks and 73 Carl Title: Re: VHF SDR?
