Thank you for your dilligently researched and produced videos. Shortwave listening was the central passion of my youth with a dedicated area of my basement pad in our family home for a listening station. Countless trips to Radio Shack in the 70s, not to forget the mailbox! I recall coming in 4th in a Radio Prague contest, hearing part of my essay read over the air one evening 🥲🫶🫶💓 Thank you so much for this video!
Your post did my old nostalgic heart good. I listened to SWR from 1976 to 1995 (Toronto, Canada | 1937 RCA Victor to Realistic DX-200 to Kenwood R5000 with tuned, inverted-V dipole antennas) and operated "World Radio Transcription Service" on the Association of Progressive Communications from 1991 to 1995. Your comment about the Voice of Korea was spot on. I miss those days so much with reception reports and QSL cards.... "You can't do better than send us that letter." 🫶🫶 Thank you for a dedicated, professionally done YT channel!
14:43 is HF financial trading data. 40kHz wide with a gap in the middle seems to be the waveform being used. It is used to transmit share trading data to avoid the inherent latency of the internet. Millisecond delays can cost many $$$ so HF radio is used due to the immediacy of the transmissions. Gilles shows this waveform on his Official Shortwave Channel here on UA-cam for those interested.
@@AdamSWL Awesome!!! Thank you! I’ve read and heard about that but never knew the frequencies they used. Mighty powerful signal considering I checked other sdrs around the world and the signal was there. Maybe it can be used for trading and OTHR in the future 🤣
14:32 I've always been curious about these signals, hear them all the time above 27.405mhz, I read once that they were from ''Wave rider Buoy's'' But never found anymore about them. Would love to know more
On 16155.4 I believe that there may be two signals overlapping. The underlying one I believe is either Codar or Wera, both radar signals for measuring wave conditions. The WERA system (WavE RAdar) can process back scatter from up to 200km, so does go over the horizon. I don't fully understand how it works. The other, Codar, is 'Coastal ocean dynamics applications radar', and seems more short range. I'm in the UK and during daytime, there are always such signals around 13500 kHz and at night around 4600 kHz. I am in the southern part of the country and I imagine these radars are situated around the English Channel. If they are pointing in my direction, they are probably on the coast of Northern France. These types of radar are all over the world and play a part in maritime weather forecasting. Some have a faster sweep than others. the 4600 kHz sweeps are much slower than that around 16150 kHz. There seem to be more of these signals in more ranges over the last few years. I have even heard them up around 26000 kHz when the conditions are right.
Thanks for that peak into SW i was picking up that wwv here in Scotland at 2100 UTC ( very weak ). Amazing. I'm getting a station 15.190 s5 good readability , i belive radio Filipino radio? I am very lucky to live in the countryside in a very low noise environment. Using my ham aerial 2×25 metre (164 feet )doublet at 12m 40 feet . Which works very well as a general Short Wave ant my RX a Xiegu G90 . 73.
The last signal resembles the Ghadir radar from Iran. Also very present on 10-11m. However seeing the SDR is in USA, it`s surprisingly strong. So could be a birdie or local interference too.
@ Oh - I just remembered I checked other websdrs around the world and they also were receiving that same wide 50 khz signal. (Can't believe I forgot that)

@@karcinogen agreed!! The signal wiki seems to suggest these are OTHR bursts but I’m just not quite sure.
I’d like a weekend somewhere where people come together with their different radios to pick each others brains about what they hear.
@@bikeguyhd1035 That’s actually a very good idea. Maybe my first livestream will be that!
@@shortwavelistener sounds good!

That's great! I wish I lived in a more radio quiet area.

I was wondering that as well - but checked the websdrs in Sweden and Australia at that same time and the signal was there as well (much fainter).
Last one resembles internal interference of the radio itself...
Could be - but it was sporadic - on and off - maybe a kiwisdr issue?????
@shortwavelistener could very well be! But without knowing at what frequenties that SDR works, we will never know...🤣
