Web-Spectrum: Web-Based Spectrum Analyzer and GPS Signal Analyzer with RTL-SDR Support Over on GitHub we've recently seen a new open source program release called "web-spectrum". Web-spectrum is a multi-purpose browser-based tool. One interesting feature is that it allows you to view the GNSS spectrum (via a connected RTL-SDR or SDRplay with an appropriate antenna), decode it to a position, and also analyze the signal for jamming.

Have finally got round to updating to the latest version of SDRConnect for my SDRPlay RSP1B, currently monitoring PMR446 channel 1 with it, using a small magmount antenna on my curtain rail so reception isn't that great #hamradio #sdr #sdrplay #pmr446

I solved the problem, and it was about the stupidest thing imaginable. Not loose cables, or a bad connection, but an #SDRPlay RSP1 serial number issue. When the API is initialized after a reboot, the old RSP1s get a randomly-generated serial number instead of a fixed number.

This month's edition of #practicalwirelessmagazine has landed. Not a very promising front cover, promoting CB radio 😅 I haven't actually got around to reading last month's PW yet... This month covers the new #SDRPLAY #nrspst networked receiver and how to build a portable one element beam.

This month's #radcom magazine has landed from the #RSGB #amateurradio #hamradio #sdrplay #SDR - including the very sad news of the untimely passing of Gillian Coull, RSGB sales administrator. R.I.P.

OK, so now I need to accelerate the reinstall of my laptop and get the correct #SDRPlay #SDRConnect and #QSSTV setup and running.

#Airspy HF+ Discovery vs #SDRPlay #RSPdx 40m band #WSPR decoding performance full article at groups.io/g/wsprbeacon... - This is the conclusion of 4 weeks of tinkering and comparing SDRs, now back to DX hunting... finally
#hamradio

Worth noting that the #Airspy HF+ Discovery and the #SDRPlay #RSPdx are excellent #SDR in my RX performance comparison on the HF bands. The final 40m comparison is ongoing and I expect the results tomorrow - mind you, a 14-bit ADC doesn't have to hide behind a 16-bit ADC #hamradio #swl

#Airspy HF+ Discovery vs #SDRPlay #RSPdx #WSPR #DX decoding performance on 15m band #hamradio

#Airspy HF+ Discovery vs #SDRPlay #RSPdx equal #WSPR #DX decoding performance on 10m #hamradio #swl

A small change in gain, a big change in performance #Airspy vs #SDRPlay #RSPdx wip #hamradio #SDR

#Airspy HF+ Discovery vs #SDRPlay #RSPdx I'm curious to see which one is better - 16-bit vs 14-bit #ADC comparing #WSPR decoding performance #hamradio #swl
