Martin,I'm hearing USB this morning @3:25 UTC. Very weak, and what I think are Western Pacific, South East Asian language, but don't know. The signals are not right on frequency but off 200 to 500 Hz.Ron

Martin,I have yet to hear the SSB signals there, but will continue to listen from time to time. The screenshot below shows the activity in the vicinity while I listened there. Some random digital signals that seemed to be moving up and down the freq…

What is your public IP? Ron - KA7U

That was a long service outage! I visited your part of the state a couple of years ago. Beautiful area!Ron - KA7U

Correction, the aircraft positions are reported correctly using the world map and the local map built into MultiPSK. The ability to use Google Earth or DX Atlas seems to be broken in Linux using the WINE API.Ron - KA7U

Going back to my first suggestion of how to set this up, I'd use a standard linux OS, open up 4 desktops. Setup 4 virtual audio cables (VAC) using Jack ( http://jackaudio.org/ ), select one of these VAC as the default audio source, then start a web …

Loufoque,As a practical matter, a little google research shows using stand alone applications such as HDSDR or SDR Console and SDR such as SDRPlay, should be the easiest setup. Of course you would be limited to your antenna range. I see https://www.…

Loufoque,I think with some configuration you could use Jack Audio to create virtual audio cables. Then using Pulse Audio you could configure each audio output source to be the "default" each in turn. While the desired audio output was defa…

5.8 microhenry and 3000 picofarads, problem solved.Ron - KA7U

KWEI is back on the air after being down for quite some time. 8.4 KW during the day @ 1260 KHz, and just 3 miles upstream from me. Now the OV light is on. Dang nabbit.Ron - KA7U

Thanks for posting this information. Currently I have one notch filter set for 1380 KHz. It was the only local station causing problems. The filter I made is bit wide a attenuates a wider bandwidth than I would like. Still it is quite useful. The 4-…

Here is a new one I found tonight. The digital would run for a bit and then a robot voice in spanish would say quattro and another word that I never made out.Time was about 5:45 UTC. Ron - KA7U

I had this problem with Chrome the other day and after clearing the browser cache the problem was solved.Ron - KA7U

Chuck,Winlink2000 uses Pactor on HF. Stations that forward message traffic via the Internet are called RMS Gateways (radio message service gateways). These gateways are published here:http://winlink.org/RMSChannels Look toward the top of the table …

I think it is a Pactor 3 signal.Ron - KA7U

Phil,This type of operation was talked over a bit a while back.https://github.com/jks-prv/Beagle_SDR_GPS/issues/19 It seems that a serial port is difficult to control from a web browser, and I'm not sure what it would take to write to a file on the…

The delay in the KiwiSDR can be used to advantage in Ham radio. For example when I was in San Diego I could listen on Frequency with the KiwiSDR while transmitting from San Diego and about 1.5 seconds later I would hear my echo from the KiwiSDR at h…

John,The <shift-left click> on the magnifying glass is really great. Sadly, I don't think many of the users are taking time to read the directions, at least not read them for comprehension. Still given enough time to practice, we will all figu…

One other thought, the WINE API currently requires an X86 type processor. It does not work with the ARM processors.Ron - KA7U
-
James - WA2ZKD,I used openSUSE 42.1 in this particular video and MultiPSK is being run under the WINE API without any additional DLL files. MultiPSK is not fully supported in as much as the 3rd party "hooks" don't work for plotting maps an…

Most CW operators, myself included, seem to prefer 700-800 hz for the listening tone. I've thought about changing lines 698 and 699 in openwebrx.js to achieve that, but haven't because I did not know if it would have unexpected consequences elsewher…

leaving the new decoder running on 80 & 40. Should sample for just under 2 hours before timing out. So far some nice ZL and JA spots. Ron - KA7U

Martin,OK on using a spreadsheet to cleanup the strings in dx.json. I'm looking at using grep and sed in a bash script to do it and also to search the strings for various tags.http://www.theunixschool.com/2014/08/sed-examples-remove-delete-chars-fro…
-
Martin,Wow, you have found a bunch of Pirates! I've listened to your receiver quite a bit and it is a proud receiver. Probably the best one I've listened to. So how are you sorting these stations? Do you use grep to pull from the dx.json file or hav…

http://sdr.hu is back up and running as before. I am pleased that it is. Without this web site it is difficult to find the hosted receivers around the world. Thanks to Andres for getting it back online. RonKA7U

Martin, There are quite few signals that defy description. This one looks like an over sized Stanag or maybe 4 stacked signals? I don't know, but it is big and loud. Ron - KA7U
-
I don't know what it is either Martin, but I did see this signal @ 17:25 UTC this morning. I also saw the JORN type signal at that time but up frequency about 200 KHz. Both signals were substantially lower in amplitude than your reception. At the no…
-
Martin, This may well be a form of HFDL but it isn't the garden variety HFDL used by the Airlines. MultiPSK decodes that HFDL nicely but it doesn't track with this signal at all. This is a busy section of frequencies. I keep coming here to listen an…

OK, Martin,This signal proves to be a bit elusive. It starts at indeterminate times and runs for short durations, usually. Occasionally it goes longer. So I think the short runs are announcement, or ID, and the slightly longer transmissions are prob…
