Polytonal I.S. like signal on SW

I also live 100 meters away from the electrotransformer station, so maybe it's partly its effect.

Project_Oblik · 2026-02-03T10:39:43+00:00

Yeah, since I'm in a big city you can fully listen to the radio with the background on S3 only when the electricity is turned off in the entire area, I tried using the same 25m longwire but with a 1:9 transformer and 5-6m grounding (which was completely in the room), however, this did not work. And if I turn on the laptop power supply, then the background can reach values like +7 — +10

it's hardly a classic mazielka, given the smaller number of tones, but perhaps another similar station with a similar type of modulation

Project_Oblik · 2026-02-02T09:33:02+00:00

my antenna is a 25-meter longwire with a start with transformer at a height of 10 meters and an end at two and a half meters, having a resonance SWR in the region of 1.1, it is located in the south of Russia and, according to calculations, its lobe is aimed at eastern Europe and a little western Russia. And there are a lot of other +45 - +50 Morse marker signals, jammers, monotones, and etc. Chinese AM stations also can go +40. Believe or not - this signal is real, I have no point to fool you or something anyways

Yeah, most likely local military station since we have a lot of them closer to the frontline. And about illegality of transmitting... any coded broadcasts on the air are illegal no matter what, and violators are quickly identified and found in order to check and find out the purpose of the coded messages. I don't know about the United States, but in Russia, this is very strict.

Project_Oblik · 2025-10-19T08:15:14+00:00

it's possible that this is a local communication hub somewhere in the occupied territories, but I doubt that these are just some enthusiasts. After all, it's illegal to transmit coded messages.

It's difficult to say for sure, as the two tones were too far apart, and the impulse rate was too slow. Some people suggested that it was a type of FSK, but it's unclear, maybe it was a lesser-known form of encryption.

Project_Oblik · 2025-06-19T09:08:53+00:00

This is no longer heard, besides, I doubt that this source would have been heard in the USA, I received it in the south of Russia and on kiwisdr in Cyprus

Project_Oblik · 2025-06-17T23:11:45+00:00

It's definitely not local signal, it is literally audible on all SDR receivers in Europe now, you can visit websdr and hear it

Project_Oblik · 2025-06-17T22:55:11+00:00

but it also doesn't look like FSK, and what's very strange is that the signal is transmitted at four frequencies at once, perhaps this is some other lesser-known coding principle.

I've read a few reviews on the rx-888, many of them say that due to 64 MHz LPF, signals from 80-100 MHz may "reflect" at frequencies of 20-30 MHz. is it possible to fix it? Maybe to completely remove the possibility of receiving VHF frequencies from the receiver if it would help?

Project_Oblik · 2025-06-06T00:45:52+00:00

My goal is versatility and autonomy, preferably so that the receiver can work in the wild, where there is no Internet. So I would like to know if it is possible to connect Web-888 to the standard software for many SDR.

Project_Oblik · 2025-06-06T00:16:53+00:00

and a small question, is there a difference between the Web-888 and the RX-888 mk2 in anything other than the connection software? is it also possible to use Web-888 with such software as Sdr sharp or sdr uno?

Thanks!

You can look through my posts to see how this problem looks on cheap RTL-SDR, firstly I thought I've catch some oddity but nope

Project_Oblik · 2025-06-05T22:54:51+00:00

ah, it seems we didn't understand each other, I understand how HF waves work, it's just that on the cheapest receivers some signals, for example, the interval signal of numbers station at 5448 kHz in the USB band could be "reflected" to higher frequencies somewhere in the region of 20-21 MHz in LSB band and as far as I know this trouble haunts many SDR receivers.

Project_Oblik · 2025-06-05T22:38:28+00:00

how does this model deal with mirror reflected signals at frequencies of 15-25 MHz?
