Re: Ozark Patrol Regen Receiver A+

Hi Curt:

This time frame was about 60 years ago so this is what I remember.

I got my start building regen receivers when I received an Allied Radio Knight Kit 6 in 1 radio lab kit for Christmas when I was in the 4th grade. One of the Kit’s circuits was an AM broadcast band regen receiver circuit that worked pretty good, as I remember. I lived in Logansport, Indiana, during my school years, and was I able to receive AM radio stations from all over the eastern half of the USA (after 12 PM when most of the local radio stations went off the air). I had two good family friends who were hams, Bob Gharis W9ZYR and John Fry W9EGV both SK. John was the Popular Electronics author of the Carl and Jerry stories and my Mom’s cousin. Both Bob and John showed me how to build many other electronic circuits on the 6 in 1 lab kit board and several were regen receiver circuits using a 6SN7 tube circuit. When I decided to go for my Novice License, I built a regen receiver using what I had learned from the 6 in 1 lab kit and a circuit from
a book at the local City Library called “The Radio Builders Handbook”. It was not the Allied Radio book but it had several regen circuits and one covered 300 KHz to 20 MHz using plugin coils. The regen circuit used three tubes and worked pretty nice. I used 80 Meters most of the time because the local AM radio station was on 1230KHz and the third harmonic was 3690 KHZ which helped me find the 80 Meter Novice band. The main problem I had using the regen circuit was the over load problem when the CW transmitter was keyed, but at the Novice code speeds, that was not that much of a problem. Since there was a QRM problem using the regen receiver, most of my contacts were in the earily evening or late night hours, 11 PM or later. I don’t remember how many contacts I made as a Novice (more than 100), but I had a nice stack of QSL cards. I sent out less than two hundred of my KN9ZLU cards because I had two groups of 100 cards made.

Bob

extremely
interesting on your first station containing a regen, and
your report on QRM c. 1958 (yes I was not yet doing CW nor
talking then).  Was this first receiver home constructed by
yourself or another ham?  Certainly it must have been
better than the 'toy regens' many of us have
experienced?  I am considering a build of a WBR regen as
something that might have better stability than my current
model regen.  Yes I was merely thinking c. 1930 QRM not
that from a later time with more hams, with less stable
transmitters. 

I do know
of a ham who has made many dozen QSOs with a haman rig, but
realize it is xtal based.  Just curious on the craft of
your original receiver.
