Buona sera. Sto usando una chiavetta rtl sdr.com, con software sdr console e dsd+ per la decodifica dmr. All'inizio va tutto bene,il programma funziona, ma dopo circa 18 sec (a volte anche meno) non riesco più a sentire l'audio. La decodifica continua, anche se con qualche errore, ma l'audio sparisce. Qualcuno di voi mi può aiutare? Grazie.

Noise across HF bands

I just got this sdr receiver, the problem I having when I try to listen to somewhere between 24Mhz and 33Mhz I'm getting some noise, anyone got a clue where is it coming from?

3 Presumably audio is the same? Sliders under the display adjust.

RTL-SDR Discussion • SDRSharp -v- HDSLR

New member using RTL-SDR V3 with inbuilt upconvertor. I have several questions so I will number them:-
1. With SDRSharp I have to insert a -40,000,000 offset. Do I have to do this with HDSLR and if so where?

2, Plenty of ham band signals on SDRSharp and I would dearly love to continue using it. But it does not provide an I/Q signal to CWSkimmer whereas HDSLR does. Is this correct?

3. Signals heard on SDRSharp are good, but are barely visible or invisible on HDSLR. Does anyone else have the same problem. If not, what is the solution.

Many thanks in advance

Satellites images in Japan

Hi Everyone !

So recently I see more and more posts about satellite images, wich i have to admit looks super cool.

I used to play with an RTL dongle back then when I used to live in Europe, and all those posts made me want to get back to it and start playing again !

So my question here is, do you guys know if I'll be able to get some data from japan ? Specifically in Tokyo, it seems like getting data from Weather Satellites can sometimes be tricky in crowded area, and well, Tokyo is one of the most crowded ones.

Also, is there a specific satellite I should focus on ?

Thanks !

Hi all, next question, im going to buy a second hand laptop just for the scanner/decoding etc. I would like to know what i should use, windows 7/8/10 etc And what would be the minimum or the best types of speed, ram and all that side of it, sorry again im not to hot on all this, i want to start with dongles etc and work up to better kit in the future, so i need a machine that's a bit future proof with speed etc, im looking at spending up to £200 on a second hand machine, unless someone tells me different...thanks a lot tadg

Satellites over Africa

I’m really interested in capturing satellite signals (especially weather sats) but I’m based in South Africa, and as far as I know there aren’t many I can see from here.

Are there any interesting sats I have a chance of catching?
