[ARC5] "The ARC-5 Triple Superhet"

[Mike Everette]

I once built the ARC-5 Triple Superhet.  Like an idiot, I let it go at a hamfest... it worked amazingly well.  In fact, the selectivity was so sharp, and the radio so stable, that some years later when I operated Field Day on 80 CW using a borrowed Ten Tec Jupiter with 300 Hz selectivity (my first encounter with that radio), I was reminded very much of using the ARC-5 setup.  (Don't laugh.  You need to try it first.)

I too wanted to find an R-25 or ARA 1.5-3 MHz receiver to adapt for 160 with this setup, but never found one "doggy" enough.  Not about to hack my NOS/NIB example!

Something interesting, regarding my long lost receiver.  I went to a hamfest in Durham, NC back in the mid to late 1990s, and on a table was a 6-9 receiver with "Free if you want it" on its price tag.  Never being one to let an ARC-5 go begging, I took it home.  When I opened it up, guess what... it was the 6-9 from my receiver!  There had been no sign of the 3-6, the 190-550, or the triple rack at the hamfest.  So, I have 1/3 of a second attempt, and have found a klunker 190-550 which is an excellent candidate for the low IF.  Now, for a 3-6....

Ken, if you don't want the setup you have, I'll give it a home!
