Channel Marker D 16331.7 kHz / Russian Military Beacon This is the first time I've heard this Russian beacon. The signal is weak, but the Morse code -.. can be heard clearly. I've also been receiving a Russian Morse code signal on the 15928 kHz frequency lately. Those codes are groups of letters and numbers. I'll post an image below.

This is the image I mentioned earlier. I used Sorcerer’s CW decoder to view the contents of the transmission. It sounds very fast, and sometimes the signal comes and goes, so there are bound to be transcription errors. I’ve been seeing this transmission reach Paraguay for several days now. Every time I see it, it follows the same pattern: groups of letters and numbers consisting of 4 to 5 characters. But from what I've read, each group should consist of 5 characters. The weak signal causes the signal to be "disassembled"

Marine Radiofax XSQ Guangzhou 16826.3 kHz (Wefax) I was only able to capture two images, one of which was partial. This is the first time I've received the Wefax signal from Guangzhou. Until today, I had only heard Volmet and beacon transmitters from this location.

Navtex/SitorB SHN Argentina 12579 kHz. Nautical Radio Announcements I usually check the messages on the frequencies used by Argentina’s naval hydrographic services, and today the first two caught my attention: Firing tests (I assume this is a military exercise) Suborbital rocket launch test The image in the post shows both notices in English. About 10 seconds into the video, the screen zooms in so you can read the original messages in Spanish more clearly.

DWD 2 Pinneberg RTTY 11039 kHz The video starts with the audible RTTY signal from DWD with SDR# and then the FLDIGI captured, zoomed in so you can see the text in the capture better.

Yesterday I posted this on Reddit in case it helps anyone else who wants to try DWD RTTY with FLDIGI: I was finally able to receive a clear RTTY signal from DWD. I could always see it, but I couldn't decode it because the signal was weak, and I also had a bit of trouble getting the FLDIGI settings right. The limited information available online about the settings never worked for me. That is, until I read here that someone mentioned it worked for them by switching to CW mode in the SDR# and FLDIGI. And that worked for me. I didn't get good reception with the MLA-30 , but the K-480WLA did the job. FLDIGI configuration:

Radio Ext. España 17715 kHz - Antenna comparison w/ the Standard C6500 When I recovered this radio, it worked fine with a long wire antenna, but when I tried the MLA-30 , the reception was very poor; it seemed to overload the radio. But I didn't worry about it, since the radio was working and that was enough. Today I tried the K-480WLA, and it worked better than I expected. The first 30 seconds of the video are with the standard wire antenna (16 AWG), approximately 30 meters long. You can hear some persistent background noise, but the reception is relatively clear. The next 30 seconds are with the K-480WLA, and you can hear that it significantly reduced the background noise and improved the reception quality. The last 15 seconds show how I made a basic connection to the Standard C6500. Now that I know it works, I'm going to build a custom connection for this device.
