For a while now I've been hanging on to a working version of pcrd - the linux control program for Icom PCR-1000 scanners. This version will compile with the latest gcc based distributions and work on all known Linux distros. You can find it here. It seems to work well here - the only issue I encounter is sometimes getting the unit to turn on - however after that, it tunes fine for as long as it's turned on.
If you do notice any problems with pcrd, feel free to let me know - I'll see what I can do about them. I want to add DSP support, but I don't have the needed details to do this as yet, so it's on the todo list.
