Sad I gave up my PDP's too many years ago. I had a digi-reader and ASR-33. Program once and load the punch tape from there on. Memory was a premium, not like todays inneficient waste due to cheap memory. Dennis

I think I'm in over my head with this one. There are far easier ways for me to try to receive Loran C, and I have no shortage of projects. So... Forgive me if this is not allowed on this reflector... Free to a good home (after shipping): One Austron 5000 Loran C receiver. Untested. Decent physical condx. See earlier post from me for a link to photos.

You got more replies from heavy hitters than I ever did. (Excuse me, Magnus, if you do not consider yourself as a heavy hitter.) What you have is a device that has a CRT display and Nixie displays, an antenna connection, and several 50 pin connectors. A creative bit banger could make a marvelous display from this unit. Truly creative bit bangers are hard to find these days. Have I challenged anybody here? Andy is one of the good guys.

This has all been a positive experience for me. Had I not taken that receiver, I might not have learned everything I have learned about Loran C in the last several weeks. And the other equipment you gave me is in use and works great, by the way. This list is a great resource. Maybe the '5000 finds a new home... or maybe I part it out.... It's still all a plus on this end.
