OK, this is a different signal. It varies in duration and there are long periods between transmission. It doesn't seem to fit anything I've seen before. Occasionally FSK preceeds it. While uploading this video, a G2-ALE signal came on just slightly …
-
Thinking that if these signals are from Korea, then a KiwiSDR in Japan should receive the same signals and possibly stronger. So here is an image from http://travelx.org:8073/ . And sure enough, there they are. Propagation tends to show this signal …

Yes John, Thank you very much. Nice set of new features for WSPR extension. Ron - KA7U
-
Martin,Thanks for the link. I've used it, but it doesn't seem to include the signals in question. It is a very helpful site though.Ron - KA

Here is another wide digital signal that I have not yet identified.Ron - KA7U
-
Something seems to be intermittently dropping sensitivity on the VLF. Signals will be sharp and then suddenly disappear. Ron - KA7U
-
I have not been able to identify this signal. I received it again tonight on a lower frequency. Ron - KA7U

Some of the decoded text from a short session with HFDL. Ron - KA7U

I used a series LC circuit to attenuate a nearby MW station on 1380 KHz. The Q of the filter was a bit broad and took down some neighboring stations, but it did solve the problem of spurious signals up and down the band. This calculator makes it eas…

I don't intend to use your forum for a logbook, but these signals are new to this radio station. Ron - KA7U

JJy from Japan? Propagation must be good because it is so cold outside?Ron - KA7U

John,That was an informative read. So these CKN CAN signals are coming from Aldergrove. Ron - KA7U
-
Found it labeled on the Vancouver KiwiSDR, CKN CAN, Vancouver, MSK. Whatever that is.Ron - KA7U

Sorry, poor screenshot of the KiwiSDR desktop. Here is a better one.

I'm using cell phone internet from Phoenix, AZ, USA and connecting to my kiwiSDR http://ka7u.no-ip.org:8073 which is located in eastern Oregon and connected to a wireless ISP http://www.mtecom.net/weiser. As you can see from the images attached, JT6…

John, So no developer sanctioned Facebook KiwiSDR page then. A shortwave comments and questions category would be nice for me. So what about WD2XVN. The FCC shows it licensed to the Boeing Company for experimental research @400.0375 MHz but I haven'…

John, I checked Your links and Antonio's blog. I saw he was using the Krypto500 software. I worked more with Sorcerer and found that the FAX module worked nicely, but the DGPS module decoded the lat/lon corrections but not the location and transmitt…
-
I found a manual for Sorcerer here: http://www.udxf.nl/Sorcerer-Installation-and-Operation.pdf And a screen shot showing 100% confidence and 0 errors, so in this case the stanag signal seems to be properly tuned.

John, the extensions are a very elegant way to use decoders and it would be wonderful to have a full compliment of decoder extensions, but as you point out, without available source code, the work is very hard and time consuming, I think. Even with …
-
John, I doubt there is much I could suggest about source code for a MSK/DGPS decoder that you haven't already considered, but I do wonder if an HTML controlled application such as Spectrumlab could be incorporated into KiwiSDR?http://www.qsl.net/dl4…

DGPS DX for tonight is: Station 824, DGPS,Andenes Andoya NOR 311.0 Khz TXID 515 100bps. Distance from Weiser, Idaho to Andenes Andoya, Norway = 4234 Miles.Ron - KA7U

The "idle mode" or "monitor mode" when connection slots are idle, would be a great feature. Users could then interrupt a monitoring WSPR session and the WSPR session would resume when the user disconnects. That would be effecient…

I uploaded a video of this process on youtube. It should be live @ https://youtu.be/5grloH5outs
-
Apparently it is not going to be a problem. I am running 4 instances in one web browser on one computer, and the mute button is enabled on all screens to shut out the noise. Here is the current listings from listening to 4 different WSPR frequencies…
-
John,Thanks for pointing me to the hidden menu! I didn't think to click on WSPR under the extensions tab. Don't worry though, I've always been this way...So I have the call sign and grid square now displayed. Notice the spots are now being uploaded …
-
John,I removed the low pass filter and replaced it with a series LC circuit, 4000pF-3.3µH, and tuned the coils on the T50-2 toroid until it pretty much centered at 1380KHz. During the day that is the very strong station close by to my antenna. 15KW …
-
John,That gyrator discussion is a bit intense. I think I understand it well enough to think about it though. This web site is still active: http://cliftonlaboratories.com/z10020_am_medium_wave_band_reject_filter.htm and I've written to Jack Smith as…

John,Thank you for the link to Dr. Carol F. Milazzo's filter. She certainly puts thought into her projects and is very good to share them. I subscribe to your youtube videos and have tried a few of her setups. I am wondering if a band stop/notch t…
