With a good antenna you can even receive packets from satellites and the ISS
In short, is a USB Tv receiver that you can "hack" (use different drivers) to use it as a wide band receiver for under 15€.
Can anyone point me a bit where to look, what to read to achieve it? I have good skills in programming and not bad in electronics but I'm starting to feel very desperate with this. I have also read the APRS spec and I understand more or less the "string" I want to send but I still don't understand the way.
I really can't find well how to do it, what code should I write. I'm stuck in the transmission to decode with QTMM (second point).
I don't know which one you're trying, but VB-Cable is free and effective alternative to VAC: They should, if properly installed, simply adapt to the sample rate and other relevant characteristics of the connected audio ports. Virtual audio cable programs do not generally, unless there is a lot of clock skew and resampling between the PC, the audio interface and the radio, require configuration. SDR# (SDR Sharp) does have native support for VAC, and I would recommend using that as the radio front-end.Īnyone familiar with modern GUIs should find SDR# simple and intuitive.įor the "decoder", I would recommend fldigi as it has broadest selection of modems and perhaps the best overall sensitivity of the multimode suites:įldigi is well-documented and, because it used by tens of thousands of people, there are a plethora of tutorial videos available.
I will say that most of the programs that work with the economy-mined SDRplay don't have a true virtual audio cable connection and that most digital-mode software struggles to cope the audio that passes through the entirety of the Windows audio subsystem (assuming you're using Windows, no OS detail). I'm sure many of us would like to help, myself included, but there isn't a lot in the way of detail in this post. I am an engineer and have to deal with complex applications all day at work but geeez these programs seem mysterious when it comes to actually making them function.Ĭlick to expand.This would have gotten more visibility in the "Working Other Modes" forum. I would also pay for a decent decoder program (IF IT WORKED!).Īnyway, just looking for some advice on which programs to use and how to set them up. If someone made an SDR interface that did the control functions of the radio and could decode many modes I would buy it but I don't see that out there. VB Audio is the worst setup wise.can't make heads or tails out of how to use it. None of the virtual audio programs have a decent UI that is intuitive. I can copy CW up to about 12 wpm manually but I want to copy not only CW but various forms of RTTY etc. Also, when I try to select the sound card input CW get offers me only one selection which is the mic input not audio or playback. Both CW GEt and CW decoder give me random garbage (ee eee ee or tt t ttt t). I have set up several virtual audio programs and so far no luck. I have tried several like CWGet and CW Decoder etc. I set up my SDR play and have been having a lot of fun with it but I want to be able to figure out how to decode various data and CW signals.
