Господа, а знаете ли вы о приборе МТВЗА-ГЯ (Спутниковый микроволновый сканер/зондировщик атмосферы), расположенном на борту аппарата "Метеор-М"?
И о том, что информацию этого инструмента тоже можно принимать и расшифровывать. Подробнее о приборе по ссылке:
http://d33.infospace.ru/d33_conf/2008_pdf/1/32.pdf

Информация от данного инструмента передаётся в дециметровом диапазоне в потоке HRPT. Чёрно-белые снимки - радиолокационные изображения поверхности Земли в различных диапазонах.

Изображения получены при помощи самописного софта, других приложений, извлекающих информацию сканера МТВЗА, в Интернете не встречал.

Comment on RTL-SDR Tutorial: Setting up and using the SpyServer Remote Streaming Server with an RTL-SDR by DDancer

Will SpyServer work with a Raspberry Pi3 and dual RTL-SDRs monitoring a trucked digital network like a local Fire Department?

Доброго дня. Подскажите как правильно, sdrsharp, слушаю частоту с нерегулярными передачами. Каким плагином возможно организовать запись звука, с пропуском тишины, например на ночь комп оставить, и утром прослушать именно речь,ее там немного может быть например.

Comment on Using our new Dipole Antenna Kit by UA9098SWL

Yeap, it works fairly well. You should calculate the exact length for both elements of dipole (don’t forget to substract 1 cm from both elements, because 2 cm is in the base). Place the antenna horizontally in V position, 120°, then you want to reduce sample rate of your dongle to filter out airband signals. Then you need to adjust gain parameters (for GQRX on Linux/Mac OS use r820tweak utility from github) or turn AGC on (may cause overloads – 8 bit is 8 bit). For the best results use LNA, such as LNA4ALL, but switch off AGC in this case and adjust gain manually.
I get nice pictures with this dipole with both v3 dongle and Airspy R2 being located near the airport. Rule of the thumb – tackle with gain settings.

Anyone had succes with this dipole antenna and weather satellites? I made sure that the satellite NOAA15, NOAA18 or NOAA19 are in reach (website: https://in-the-sky.org/satpasses.php?day=16&month=11&year=2017&mag=900&group=1&anysat=v2&s=NOAA+15&dl=dl), oriented the dipole antenna in 120degress horizontally facing north/south outside on my balcony with clear sky. Tuned the RTL-SDR onto around 137MHz with gqrx (FM mode) but I don’t see a single peak that resembles a weather satellite signal. I was watching around from 135MHz up to 139MHz but nothing. Only thing I see are plenty of AM communication from nearby planes. Anyone had luck with this dipole antenna?

Comment on RTL-SDR Tutorial: Setting up and using the SpyServer Remote Streaming Server with an RTL-SDR by okechobee

I’m really impressed with AirSpy’s stuff, but I think it’s a little strange that they offer the SpyServer app for linux, but it’s nearly impossible to receive (or find documentation on how to receive) the signal with a linux computer.

SDR# only being supported on Windows is a bit of a bummer.

Comment on Testing a 16x RTL-SDR V3 WebSDR System for the Satcom Band by JMG

Native vs V3: different RBW values!

Anyone here use the rtl-sdr for UFO's (not only the extraterrestrial kind but also something like: weather balloons, drones, CIA spy shit, etc. ). A friend of mine is into UFO's and this weekend we are going hiking near a former NATO airbase; and I was thinking of bringing my dongle and sdr touch. Maybe somebody can point an rtl-sdr beginner in the right direction? Or maybe frequencies where I get some theremin-like effects to scare the shit out of my friend.

scanning the spectrum tonight i came across a signal ive never seen before (ive never seen anything in this band!) any ideas what it might be? at first i thought NOAA but theres no frequency shift..and it doesnt sound anything like whats on sigidwiki.. might it be some sort of VOR?
