7998.490 KHz Hiker, a slow dasher, mild fading. First time I have picked it up

We seek to understand and document all radio transmissions, legal and otherwise, as part of the radio listening hobby. We do not encourage any radio operations contrary to regulations.
Always consult with the appropriate authorities if you have questions concerning what is permissible in your locale.
Just for clarification....
Did you listen to Twente's audio and actally hear SDHHDD or were you just looking at the waterfall?
When I listened last night I heard only a clear and slow letter D in Morse on the receiver audio even while the waterfall was showing all sorts of incorrect letters.
The other possibility is that the Russians since have a cluster of beacons and with Twente's overly wide bandwidth you might have heard some of the others at the same time. I will post my link to my audio from when I was in Fiji and had a similar experience hearing a few beacons at once on a receiver without narrow bandwidths.
7508.7 letter D
7508.8 letter P
7508.9 letter S
7509.0 letter C
There are more, just Google For Russian Cluster Beacons

Thanks. Never heard of "Twente". It is rare that I will hear things directly from Europe. Russia has been fairly reliable over this way.

I just went to the University of Twente's web SDR and tuned in 7508.7 KHz on CW narrow and there was the Russian beacon D loud and clear. Next I tuned plus and minus 200KHz and you could still hear the CW letter D with the appropriate audio pitch from 7508.5 to 7508.9 KHz. A bandwidth that wide makes it hard to determine center frequency. What was interesting is that the waterfall display was not capturing the letter D keying properly. It showed quite a mishmash that looked like a CW letter S then a D and other letters even though there was only a letter D in Morse being received.
Speaking of remote radios, I miss the one in the Mojave Desert

That's a good point on mishearing a weak Morse D as a possible Morse letter S. i wonder how good of a receiver Twente is? I have observed the Russian beacons to be very accurate as to center frequency so it should be 7508.700 KHz if it is the beacon D.

Jim, I was monitoring via the online SDR at the University of Twente, which is physically located in the Netherlands. Thanks for the read, though, mate!

It would help to have at least a rough idea of your location. In some areas that signal could be a fixed point to point service such as radio teletype so it would not really be a beacon. I cannot hear it where I am in California. At the moment I can hear the Russian beacon K on 7039.3 KHz so I have pretty good reception from that direction.
