6104khz Morse

[k9rzz]

I was parked on 6105khz looking for Central American broadcasters through the Florida Perseus receiver on-line, when this station opened up on 6104 in modulated CW (AM carrier modulated with morse code). Copy wasn't great, but they were sending something to the effect of "conditions are good, we are underway" giving the calls "B764" and "B751". A few minutes later, they come on in AM voice (same frequency), and then essentially the same morse message a few minutes later. I don't think it was a 'canned' message, because each was worded slightly different, so I'm thinking it was hand sent (with a keyer, or keyboard). Who says morse code is dead? I believe the broadcaster in the video on 6105khz is from Germany. I can't make out what the voice part is saying, but one guys either sounds Russian, or black American. ???

Good stuff thanks! Not to change the subject matter but it was interesting watching you shift and tighten the passband to increase intelligibility. It was also fascinating to watch selective fading in the sidebands.

were you using software or a website to tune this receiver?

 

[instrumentphilip]

You know your way around HF from watching some of your videos. What program are you using to listen to these remote receivers on the internet? Or is it a website?

 

[k9rzz]

Yes I do and yes. :^]

This was with software on my computer that remotely controls receivers around the world. Hard to believe, but it's 2011 and this is the state of the art!

Start by reading this thread: http://forums.radioreference.com/software-defined-radio/153064-perseus-sdr.html

then download and install this softare. This is the radio controlling ware: http://microtelecom.it/perseus/Perseusv40a.zip

When you get the software installed, open it up. On the lower left of the control screen you'll see "input select" choose "Net", then "Addr". That will give you a pop up to name your server or something, give it a name, "Okay" (this is a one time step), then you'll get another pop up that's a Google map with all the radio servers around the world marked on the map. Pick one, click once, then "okay", that will connect you to that radio, in that part of the world for a set amount of time that can vary from 5 minutes to 60 minutes (dunno who sets the time), and then you're free to tune around, change modes, change the filtering, noise blanker ... everything! You can read more about the Pegasus radios and the network in other places on the web. There's also a email list that's really handy for keeping up to date on who's got their radios on or off line such as the gentleman in India, or the one in Australia. Those don't appear on the map too regularly. I tell 'ya, I'm hooked! :^]

Lastly, I use "Cam Studio" for the screen grabs, and yes, all this software is free (the Pegasus trial is good for 60 days).

OH, one more thing. You can also download some Perseus .wav files that many owners have uploaded that also allow you to 'tune around' during that time frame the file was recorded. They usually do it for a few minutes at the top of the hour, so you can tune from frequency to frequency and pick off all the idents. It's quite amazing! You can tune around with a radio in Russia and listen to the aeronautical beacons that they have in the AM BC band. Really. Or, tune around on a radio located in Tokyo. See if you can find a station in English (there is one) or from there you can hear all the stations in North Korea which isn't very far away.

Thanks for calling me old XD And yeah I downloaded it from their website but it is only the trial version and I cannot click on the " Net" or "web" option because of it being the trial version. You pay for the version that you have?

Thanks,

[k9rzz]

Nope, the trial version is the one I'm running. Version 4.0a. Perhaps reinstall.

Make sure the version you installed is from the software link k9rzz posted (version 4.0a), not from the Perseus web page or from the thread he pointed you to. The Perseus web page links to an earlier version, I think it is V3.0Beta1.

Prior to 4.0a the "Net" and "Web" options were not activated.

T!

OKay So I got the right version now and the window pops up to pick a SDR I click one it says I am connected and gives me the count down I have ( How long I have to listen to the SDR ) But it does not show me receiving any audio or signal just a blank screen when I should be seeing carrier signals on the display.

 

[k9rzz]

Hmmm. Try another SDR receiver. Once you get connected, the audio should just come right on, there is nothing that you have to do to start.

Back to 6104khz, they are on there nightly, voices are clearly in english, and tonight in morse they sent "we currently have 3 vessels on the way". Whatever that means. Call signs were different as well.

Have you forwarded the port (UDP and TCP 8014 I think) if you are behind a firewall? Or added the program to the trusted list in Windows?

T!

You have to open up the port on your router for it work correctly. I've done this multiple times and as soon as the router saves the settings, the audio comes thru.

Neat stuff. Morse LIVES! I went to the youtube link and copied this:

HAVE TWO VESSELS UNDER WAY. ALL CONDITIONS REPORTED AS NORMAL. K
DE8***3 DE B785 RGR COPY ALL K

EAD K BB764 DE B751 CURRENTLY HAVE TWO ***S UNDER WAY . ALL CONDITIONS
NORMAL. K B

Some QRM and QRN could probably be filtered out to get solid copy if desired but wouldnt it be interesting if the two vessels were Blackhawks.headed for UBL's compound...
