Благодаря! Все още се колебая дали да го задържа. Има значителни изкривявания от НЧУ, които лесно се чуват на слушалки, особено на ФМ и силен сигнал.

@@PavelYonchev Какво означава НЧУ?

@@ВладиславНиколов-ц4ь Ниско-честотен усилвател. В този случай, трябва да се провери точно, за да е сигурно.

Благодаря! Радио Ватан, нали? С дълга жица и заземление ако не сте опитвали - това дава прекрасни резултати. Пак навън и далеч от всички смущения. Спомних си th-cam.com/video/4oijly4xLRU/w-d-xo.htmlsi=NgfGPuRhvFbX9-6m

😂 Don't do that. They won't have electricity to power the lights on the streets.

"Sound of Hope (SOH) is an international Chinese-language radio network. Along with New Tang Dynasty Television and The Epoch Times, it is part of a network of media organisations established by practitioners of the Falun Gong new religious movement. SOH serves the Chinese diaspora in US, Europe, Australia, Japan and South Korea on mediumwave and FM and broadcasts to China on an extensive number of out-of-band shortwave frequencies. Programmes are in Chinese and Cantonese, and also include relays of Radio Free Asia at times. Transmitter sites: Pingtung and Miaoli, Taiwan - all transmitters are low power - 1 kW or less " British DX Club Asia on Shortwave.

@@PavelYonchev I appreciate that quote, but for the transmitter power info - it's rather unrealistic; for instance, even 10-20 kW stations from W.Europe are barely audible in the E.Europe... Chances are that the "British DX Club" took info from the "short-wave info" site, who can only display 3 digits max for "Pwr", and for 1000kW/1MW stations simply "1" is rendered. I don't have any reliable source on the subject matter, so that's just a guess no one cares... 🤓

@@barmaley-division It's surreal to me too, but in radio reception have moments when the laws of physics that we know don't work.

@@PavelYonchev Let it be so.😌

Nice to meet you again! From parts of a soviet radio receiver.

Thanks for the help! For control, I listened to PANASONIC RF-B45 and QODOSEN DX-286 on the same frequency - the same radio station was played there. Only I wasn't happy with QODOSEN's poor performance.

One radio transmission is 1 kilowatt, the other is 300 kilowatts: www.short-wave.info/index.php?station=R.ROMANIA%20INT. In this source is 300 kilowatts: www.bdxc.org.uk/europe.pdf 1 megawatt seems very strong to me, I have never encountered more than 0.5 megawatt on shortwave.

Thanks! Agreed :) with my primitive antenna at home. Most receivers are dumbed down by the massive interference overflowing from this cable.

@@PavelYonchev Sure, the cable must be coaxial (75/50 Ohm), but in my case even a 10m-long coax becomes an FM-antenna with the cheap receiver. In its turn, TEF6686 is FM interference-proof on AM/SW.

@barmaley-division ... and that coaxial should be attached to the antenna at least 1.5 meters outside the building, that there should be impedance matching, etc. n. :) I have my sights set on the AM waves.

@@PavelYonchev That would be an ideal scenario... In my case for AM I have a 130 cm telescopic antenna sticking out of the balcony window + grounding. Also, a 25 cm loop antenna which receives all the EMI. I want to try building an anti-interference magnetic (ferrite) antenna - very soon.

​@@barmaley-divisionYou are way ahead of me. Only success!

I'm glad I helped!

Thanks! Here, from 10 days the broadcasting is heard every night, with different quality of radio reception.

Thanks!

@PavelYonchev welcome

Thanks! ! It's still not, but it's a decent reception. I had an amazing mass FM tropo 3 years ago that got me back into the hobby.

@PavelYonchev On TEF, even without summer tropo, I can still hear two radio stations from a neighbouring country in the late evening - daily; such a mighty radio chip. Antenna is a factor too.

Thanks! A rare model, that's why I bought it despite the erased inscriptions. It is heard that it manages to pick up weak radio transmitters (if only 1 kW is to be believed). Before it came another Greek radio broadcast, Radio Canados on 1440 kHz with a much stronger signal, but it was towards the end of the night's broadcast. Again, I can't believe it's underpowered, only 2 kW. However, it may turn out to be true. :)

@@PavelYonchev Cool, I haven't heard anything from Greece on MW other than the "Greek pirate", I can hear him literally on the daily basis. There seemed to be a few weak (1-2 kW) Greek radio stations broadcasting these days, let's see if you'll be lucky enough with the new receiver. 🤓

@@barmaley-division Many thanks for the wishes and information! AKAI APW20 still no QODOSEN DX-286, but gives hopes of a very good performance!

The radio is reminiscent of a Grundig G3 design. Also sold as Anjan DTS-09 and BRIGMTON BT354.

@@PavelYonchev Yes, indeed! For some reason it feels like if it was made by Sangean (I mean all 4)

Hi, AKAI APW20. That's how I bought it, without the inscriptions. The radio is technically perfect, strongest on FM.

شكرًا لك

Thank you! That's the interesting thing. Despite the improved reception, the radio signal does not reach with the usual strength.

@PavelYonchev I don't think it has "improved reception" - it's still an old good SI473* chip; the same or similar to what's in my radio too. 😌

Not one of the favorites.

Radio Antena Satelor este un radio excelent!

I don't understand the question well. This radio only receives with the internal ferrite antenna. Radio reception in an apartment, without additional devices.

@@PavelYonchev Excuse me. I asked you about the location where you have received the 540 khz frequency and about your device.

@@tamaskovacs6546 Thanks! Ruse, Bulgaria and Eton Field BT Grundig Edition.

An urban area is full of electromagnetic interference. I tried to run away... but I found myself close to a retlanslator.

@@PavelYonchev I have installed two antennas on my balcony, and deliver signal via coaxial; otherwise I wouldn't be able to receive anything but China indoors. 😬 (Long) wire antenna gets polluted by EMI badly, so not in use.

@@barmaley-division Thanks! Electrical grounding? 😃

​@@PavelYonchev No grounding in the wall sockets here... Everything is emitting interferences, even concrete walls 😳. I use grounding on the receiver rather 😁 - along the telescopic antenna sticking out of the balcony for MW/LW; SW - I use loop antenna mostly, without any grounding.

The external oscillating circuit in this case does not amplify of the signal, but only helps to hit the correct frequency. I will do an experiment one day with the ATS 120 through a direct connection, which is the only way possible.

@@PavelYonchev Oh, I see now; indeed, I thought you have intended to create a resonance for amplification. * I have performed a lot of experiments with my SI4732* receiver and external antennas with good results, it autotunes to literally any crappy antenna - so chances are it will work well with MA too.

​​​@@barmaley-divisionThanks! Now a very modern TEF 6686 chip. I don't have a radio with it. I considering over several models, including a car radio.

@@PavelYonchev Yes, trying TEF6686 is a must for any radio lover. It does make difference. BTW, the cheapest one I could get costed me only 38 USD; it has the same circuitry as the early "silver fish tin" ones. Those receivers may produce different results from model to model. I guess the simpler it is the better it would be for experimentation with external antennas. A used TEF6686-based car radio could be a nice variant.

@@barmaley-division The car radio Pioneer MVH-S120UB, for example, has an external FM antenna input. Phenomenal results are possible on these waves. Set up the dipole in an open place and enjoy the scan!

It didn't work out well... but noise is also a radio signal :)

@@PavelYonchev yea, but a very anoying radio signal noise is :)

Thanks! This FM radio station was present with me only one day out of seven.

I like АTS 120, because on medium waves I can do experiments with various external antennas consisting of a coil and a capacitor.

With TEF 6686?

@@PavelYonchev No, it's power-hungry; listening it for hours would be an overkill. I mostly use my compact and energy-efficient XiaoK (SI4732-A10 chip).

@@barmaley-division As far as I know the ATS 120 is with this chip. Now I experimenting with this radio.

@@PavelYonchev Yes, exactly. The results should be similar. Congrats on getting yourself the ATS 120!

@@barmaley-division The XHDATA D808's LW range ends at 450 kHz, but the ATS 120 has more. I will be doing the 477kHz experiment there.

У меня нет другого с таким расширенным диапазоном. Прием был стабильным, с одинаковой интенсивностью каждый день.

@@PavelYonchev Думал, ваш D808 поддерживает прямой ввод любой частоты. Попробую у себя послушать, хотя на такой нестандартной частоте никого быть не должно. Кроме китайцев 😄

@@barmaley-division Спасибо! Я забыл о нем. У него практически нет LW, но я попробую, когда буду там снова.

@@PavelYonchev Вот сейчас попробовал на TEF6686 (он вообще не подвержен зеркалкам) - глухо. Но у меня много бытовых помех (например, Алжир и Морокко - есть, а вот BBC4 - почти не слышно), 10-100 кВт и не услышу.

@@barmaley-division Спасибо за опыт! Мне нужно время, чтобы прояснить ситуацию, если будет такая возможность.

I don't have, unfortunately! But it's not particularly complicated.

I'm very pleased!

Thanks! BBC Radio 4, "it's tough" here, whatever the conditions. I usually listen to it at 2 UTC+2, after midnight.

@@PavelYonchev Yes, indeed. Same timezone - BBC4 could be heard only after 00:00 (EEST), and due to heavy EMI in the residential area, on a whip antenna, rather than on a dedicated LW-loop.

I wonder what the video of this great experimenter will be like - Matt in Lapland.

@@PavelYonchev I saw him posted to @swlistening that he was not able to hear anything even on MW 🙉

LW is not illegal. There are 3 broadcasts left to receive in europe.

@@optimus43175 last survivors 😞

LW is NOT illegal, at least not here in Europe. And probably neither in Russia. Some countries, Spain one of them, don't grants licenses to broadcast radios in LW band. This not means that LW is "illegal" in Spain. And... in almost all world, the NDBs (Non Directional Beacons) transmits here. These NDBs can be found today starting your search (usually) from the 350 or 380 khz, the truly end of LW broadcast band yerars ago. In some countries, the NDB´s even transmits inside the Medium Wave (MW) broadcast band and broadcast stations can't claim if a interference comes from NDBs into their broadcasts. In the other hand, MW broadcasts must care not interfere the NDBs.
