[amsat-bb] NO84 in safe mode

 In my uncalibrated-ear testing with an A/B switch on satellite downlinks, I found my RSP1A is noticeably more sensitive (with HDSDR driving it) than the FT-857D, FT-818ND, and the TH-D74A, and comparable (on 2 meters) to the KX3. While none of these are really proper satellite base station rigs, I have to believe all of these are better receivers than a $20 SDR dongle. The downside with the SDR is the almost one full second delay I experience in hearing the downlink, but I'm starting to get used to it.

Is the RSP1 superior to rtl el cheapo $20 SDR dongles in regards to 
receive sensitivity? My experience with rtl dongles is that although I 
can hear strong signals they are nowhere near as sensitive as say a 
Chinese handheld radio.
