I, and I am sure many others did it long ago. I ran HF AX.25 Packet Radio on my Heathkit HW-101. Of course, if the desire is to wed the PDP-11 and vacuum tubes, if it hasn't been done already the same could be done. I would bet I could put an old version of the KA9Q software on a PDP-11 running BSD or even Ultrix-11. And then, fire up my HW-101 (yes, I still have it) and the deed is done. Of course, I could also use my HF rig which is also of the vacuum tube genre. Drake Twins. :-) bill -- Bill Gunshannon | de-moc-ra-cy (di mok' ra see) n.
