It does have a memory leak, so will probably not run for more than a
few days. I'm working on? a fix and it should be available soon.
Apart from that it is pretty stable. Occasionally the waterfall
stops, but the modem keeps running. I know of a few people running
it successfully on 300 baud HF and I run copies on HF and 1200 Baud
VHF FM.

John, the rasberrypi binary version is interesting.
Being a beta software, have you had hangups still ? (don't be suprised if it doesn't perform
perfectly )

Yes, and there's a QT native linux version now too..

UZ7HO's SoundModem recently
added FX.25 also.

Ok, well thats a lot of information to take in, all thanks to everyone here !
I guess now I have more than one road I can go down. fact is I have not been anywhere near packet since about '94 and clearly, technology has moved forward. I now can see that the best thing I can do is get started, somehow, and gain experience. I have two raspberry pi's , a 3 and a 4 , plus plenty of radios. I will give soundcard modems a shot first, just to cut my teeth with ( hoping). At least I wont spend any funds unnecessarily, because I must,nt forget I am to some extent responsible for other members who will eventually join the board.
We will give direwolf a go and take it from there. On our team I am the radio guy, but there are a couple of smart i.t. guys who are quick to pick up and they will be helping me out with linux and software.?
I can see that some guys here have had some success with direwolf and raspberry pi, so an I ask if both FBB and BPQ work equally well? Is there any detail to watch out for with the linux version of direwolf ? And last: Is there any special thing I must do to process the audio in/out from the raspberry to the radios ?
Well done everyone, much appreciated!

>?? UZ7HO Soundmodem supports FEC and I've produced a Linux version. It does 300/600/1200/2400 FSK and a range of BFSK and QFSK modes.
I've tested both of them, talking to each other, in both directions.
Transmission errors were intentionally inserted to test the error correction.
These two FX.25 implementations are completely compatible.
FX.25 adds a lot of overhead but up to 32 corrupted bytes (not bits, bytes) can repaired in a frame.
More details here:??
There is another FX.25 TNC project but its github repository has an open bug report stating that it is not compatible with the others.

Hi John,
Actually late last night we were looking at your linux version.
We will set it up soon.?
Did you have any issues with the audio from the jack on the Rasberry pi ?? Filtering, impedance match, levels ?
thank you

The ad mentions GPIO so perhaps that covers the PTT issue.? I didn't notice if it had transformers which would make it a no go for higher speed digital.

I believe it's very similar to the FePi... The advantage is you can actually get it.... The FePi has been sold out for months.

How do you stack the Fe-Pi and a radio interface inside a case? I built the packet radio interface and I’m using a Fe-Pi and I have not figured how to stack all of that together nicely on my Pi 3B+.?
Of course now I’m waiting for some short stereo cables that shipped from Minnesota and I’m yet to see...

Hello John,
I agree with you that the Fe-Pi has been unavailable for months but
go look again as I just saw they are available again (as of
yesterday)!?? Also, I've had one user report that these sound
devices might be sensitive to RFI issues compared to the Fe-Pi so
beware there.? Might be easily mitigated by ferries on everything
but something good to know.
