Some interesting enhancements to OpenWeb RX by Jakob, DD5JFK which he seems to have forked from the original work by Andr?s, HA7ILM.

https://github.com/jketterl/openwebrx/blob/develop/README.md


Apart from the addition of wsjt-x based demodulators for FT8, FT4, WSPR, JT65, JT9

He's also added Clientside bookmarks (DX Labels or Tags) which every user can store for themselves in the browser's localStorage.

Interesting stuff.

Hi Jim,

Yes it was, but the dev extension is not listed among the rest on the extension admin page, so you can't lock it out from general users.

Hi All,

Over on Simon Brown's SDR radio IO Group, he's just mentioned the Voice Activity Detection (VAD) component of Rnnoise, and thinks that it may be worthy of further investigation.

https://people.xiph.org/~jm/demo/rnnoise/

It's written in C and is available under a BSD license, and uses Recurrent neural networks (RNN) to provide voice detection and noise suppression.

HI,

It's possible to use an external 12v supply.

However adding a 1000uF 16v electrolytic across the secondary of the big common mode choke in the "Biasing Tee" removes just about all of the unwanted noise around 60 & 120KHz emanating from the DC-DC switcher.

I think it was an oversight on their part to not include something like this.
