I bought one of these back in 1975. I think I paid about $300 plus I traded a beat-up Yaesu FTDX-560 for it. I had a lot of fun with it. I use to have pile-ups out of Europe on 20 meters running just an end fed wire and the speech processor. It really was nice on CW with the 350 and 250 cycle filters and the IF shift. 90% of the DXers couldn't even hear what I could. I'm really sorry I didn't hang on to it and had it all restored like new.
