Hi Jeff,
Here some extra info that might help:
Use BPSK AX.25 mode when decoding QB50p1, make sure non-AX25 filter is not selected. You can try to replay the file at: http://janvgils.home.xs4all.nl/download/QB50px/ to see if things are working. There three different signals in the file.
QB50p1 1200bps and 2400 bps DO-64 (Delfi-C3) with 1200bps
They can both be decoded with UZ7HO and AGW Online Kiss.
Maybe the block diagram on the following page will also help in understanding how things can be connected. http://www.pe0sat.vgnet.nl/decoding/block-diagram/

Hi Jeff,
if you use soundmodem by UZ7HO you don't need AGW Packet Engine.
Firstly start soundmodem software, then AGW Online KISS OR use the QB50p1 Online decoder. If it's connected you should see a green light.
If you successfully decode a packet you should see something like this in soundmodem:
2: <NON-AX25 frame Len=125> [18:29:19R] 2: <NON-AX25 frame Len=125> [18:29:29R] 2: <NON-AX25 frame Len=125> [18:29:39R] 2: <NON-AX25 frame Len=125> [18:29:49R]

-----Ursprüngliche Nachricht----- Von: AMSAT-BB [mailto:amsat-bb-bounces@amsat.org] Im Auftrag von Jeff A. Boyd Gesendet: 21 April 2016 17:18 An: amsat-bb@amsat.org Betreff: [amsat-bb] Need help decoding EO-79 packets.
I have been trying for weeks to set up a system to decode telemetry packets from EO-79 (QB50P1) without success. As I am new at dealing with data from satellites that is not already handled by a dedicated program such as FUNCube Dashboard, which handles Doppler tracking and packet decoding all by itself, I'm still kind of lost as to how all the required components are supposed to come together.
If I can figure out EO-79, goes my thinking, then I can go on to tackling other BPSK 1200 baud birds such as the XW-2 constellation. I will list what I'm doing below; if someone can please give me a sanity check it would be greatly appreciated.
- Receiver: FUNCube Dongle Pro+, SDR# outputting to a virtual audio
cable.
- SATPC32 tracking EO-79, correcting for Doppler, and controlling
SDR#.
- AGW Packet Engine set up with "Sound Card" TNC (the other end of the
virtual audio cable), dual port, 1200 baud for each channel.
- AGW Online KISS set up to connect to the Packet Engine. WINSock
remote port 8000.
- Soundmodem by UZ7HO on the same port 8000 and listening to SDR#,
which is set for USB, 4kHz bandwidth. SATPC32 is keeping the packet traces in the center of the 4kHz passband, and I can see the traces appearing in the waterfall in Soundmodem. The modems in Soundmodem (2 channels) are set for BPSK 1200 baud, and the reticules match up exactly with the traces I can see in the waterfall.
And Soundmodem refuses to decode a single #$%&ing thing. There is an occasional "<NON AX.25 FRAME>" that shows up in the list, and Online KISS will show a bunch of garbage, but this mostly occurs when there is nothing in the waterfall at all.
Several sites have said that I'm to connect something to something else using virtual serial ports, but none of them have really given me a straight answer as to where to connect what to what.
What am I doing wrong here? Any advice would be ridiculously appreciated.
