Listening



Hi all,
If anyone on the list would like to hear what the European Broadcast bands 
sound like both medium wave and
longwave there is a nice Web SDR available to use for free that is run by 
the University of Twente located
in the Netherlands.

This is a wideband SDR that will tune all the way down to 0kHz VLF and has 
many features and modes
controllable by the user including AM, CW, FM and SSB. Lots of bandwidth 
choices and several ways to
tune the radio including by direct entry of frequency and you can even drag 
your mouse across the waterfall display
for tuning.

The radio is located near the top of a building and uses a wideband e-probe 
antenna and is very quiet and
sensitive. It must have very good grounding it is so quiet. This is the only 
free WebSDR that I could find that will tune all the way down to VLF and 
covers the
European longwave broadcast band with good sensitivity and quality. All the 
other free WebSDR radios that I could
find in Europe seem to only cover the Ham bands.

The Netherlands is located on the Western border of Germany and is across 
the water from the UK
so it is in a nice central location for European broadcast listening. The 
BBC4 on 198kHz comes in like gangbusters
and also Germany on 177, Europe 1 on 162, etc. I can also hear many VLF 
stations in CW mode with the
sharp filter engaged and can hear NAA on 24kHz from the USA pretty well.

Here is the address to the WebSDR :

You will need a high speed line and JAVA enabled on your computer. You may 
need to lower your
JAVA security settings if you keep getting an error message when you sign in 
to the radio.
Being an SDR radio literally hundreds of users can operate the radio at the 
same time without
waiting in line to use the radio. Several times I have been on there when it 
said there were over
200 users online.
