Hi Robin, When using the AIRSPY (and mini) this summer I was finding some flashes in the RF band that were on for a few 100 micro-seconds, then off. (The plots are on my home computer so I’ll have to send these on Friday). The fraction of time the flashes are on is very small, less than a to

Hi Marcus, Two good things about the SDRplay, now that the gnuradio interface seems to be working, are: 1) Very high gain. I need about 30 dB of IF attenuation to get the levels right. 2) Very good data transfer rates. Right now I appear to be getting 100% of the 7 MHz samples delivered to

Thank for your help Chris, I have now gotten the SDRPlay connected to my telescope and the results are looking reasonable. My initial problems were with the sense of the gain values, which are actually attenuation values for the SDRPlay. It seems like the defaults are reasonable, and that probab

Thanks Marcus, Concerning your points, I thought I’d edited the Subject line to start a new thread. I’ll be more careful in the future. Also thanks for your clarification of the source code origin. I’ve also directly contacted the folks at SDRPlay. I do think the SDRPlay folks do want to be mo
