In reply to M0JLA:
Fldigi is available for Debian ARM. The Pi has a 700MHz ARM1176 CPU with hardware floating point and runs Debian. Job done.
I did a lot of simulation work on ARM1176 back in 2007 for our mobile phone SoC customers. This was when their designs were still pre-silicon. They used our stuff to develop the boot code and TrustZone secure code so that as soon as early silicon was available they were ready to start porting the phone stacks and apps as they had their basic code booting on our simulations.
I did think of knocking up a quick and dirty simulation of the Pi without graphics and floating point maths. But we don’t support ARM1176 any more as it is considered obsolete so getting the CPU simulation to compile with the new tools would be a big job. That’s the problem of working in front of the leading edge, stuff we worked on for clients 2 years back is just on sale now and anything we did a while back is more dated flares and kipper ties!
I’m sure there will be a lot of 2nd hand (unused) Pi boards for sale by summer.
