"You may or may not be aware that the ITU monitoring stations publish their
listening logs on their public website:

https://www.itu.int/en/ITU-R/terrestrial/monitoring/Pages/Regular.aspx

This page describes the purpose of the monitoring activity as well as
allowing you to download the logs as Excel spreadsheets; there's also a
search tool so you can search for logs by frequency and date.

The spreadsheets often include DF bearings with an accuracy indication and
signal strength as well as time, frequency, mode, comments etc.

They often mention the kind of things we like listening to!"

I've previously taken a look at the ITU loggings but they always tended to be a bit of a pin to trawl through.

However the new database search tool is very good. Especially if you are careful about what search parameters you set. You can then click on a individual log entry for even more detail.

It would be even better if you could download the searched results, but maybe someone will get around to writing a scraper tool :-)

Hi All,

I see that DX Engineering are now offering Ethernet filters.

https://www.dxengineering.com/parts/dxe-iso-plus-2


"DX Engineering ISO-PLUS Ethernet RF Filters are very effective EMI Suppressors that are quickly and easily connected inline on Cat5e or Cat6 network cables. Their patent pending design provides common mode RF interference and EMI noise filtering of radio frequencies from well below 1 MHz to over 100 MHz. DX Engineering ISO-PLUS Ethernet RF Filters are bidirectional (input and output is interchangeable) and they have no effect on digital throughput; Ethernet data signal levels and speed remain unchanged."

I found some notes on the subject of "New squelch algorithm for the WebSDR" on Pieter, PA3FWM's website - he uses this on his University of Twente WEB SDR
