Hi Don,

I could not afford that gear in 1963 and I still can't afford it today, (It hurts to end up on medical retirement 15 years early )
I look and dream as much today as then and do with what I can resurrect out of junk and spare parts.

I usually get enough nostalgia walking around hamfests and looking at the boat anchors for sale - seeing stuff I either had long ago or those things I lusted for and could not afford back in the day when they were available.  Wisdom has always prevailed and I have resisted the urge to take one home.

You guys have got to stop this stuff!  I have been following this thread recalling my novice days.  I never did get a regen receiver to work to my satisfaction, but I built my novice transmitter and struggled with an NC-54 (or was it NC-53) receiver.  I did not work many stations until I obtained a BC-348J receiver.

Later, I went on to build my own version of the Lew McCoy HBR-16 which featured an Eddystone slide rule dial and used salvaged (and capacitor switched coupling for variable selectivity) 85 kHz IF transformers  salvaged from BC-453 receivers.  I added a Q-multiplier at 85 kHz and it had really good selectivity.  I dubbed it the HBR-18 because it used 18 tubes.  It is still in the attic storage, and I might resurrect it one day.

These days, my K2, K3 and KX3 are more than I need, but your comments have gotten me thinking about restoring that HBR-18 and the NC-101X that I have in the attic - even though I know that my Elecraft rigs are far superior performance-wise, much lighter and easier to use than those boat anchors.
I may even try my hand at a regen again based on some of the stuff presented by George Dobbs at several past FDIM seminars.

Thanks for the memories.

Hi, Scott, n7net here.


I have a WordPress blob called QNCW.ME. It began as a paper CW journal in the early 1990s and has finally morphed into a blog which is visited by a few. Yesterday it was a friend in Italy. The day before it was someone in Brazil. 


The current thread, Regent, caught my attention. There is a great deal of nostalgia and meaningful information in these posts. I'm wondering if there is any objection to my moving this Regen thread to my QNCW. 


I won't do it without permission.

Re: Ozark Patrol Regen Receiver A+

 

Since the post I spotted and bought a nice TS-520SE off ebay. It
arrived yesterday and looks as nice as in the pictures. Of course,
shippers can do amazing things and in this case the plug managed to work
out of the Remote VFO socket and get smashed to bits. Fortunately, the
pins required for normal operation were only bent slightly and I was
able to get the rig receiving just fine (moral, remove, wrap and note
fragile parts). Even though I had a TS-820S and TS-830S in years past,
I thought I had forgotten how to tune these guys as I couldn't get any
ALC reading. I removed power and then the top cover and reseated the
driver tube. Plugged it back in and powered it up and it tuned up just
fine on 75m even though the meter seems a bit "peaky". Closed
everything up and about an hour later I wanted to retune on 160m and
again no ALC indication when trying to peak the Drive control.

It's an old radio and I'll go through the alignment procedure one of
these days and get it going in fine fashion in time for SKN. The
receiver sure sounds good, though.

fascinating discussion on your first ham receiver being a homebrew regen! 

it was in my teen years that Allied Radio sold out to Radio Shack, and the end of Knight kits - I remember the fire sale but I had no building experience or mentors then, and Knight kits had become as pricey as Heath. 

cool story on the AM harmonic being a nifty calibration tone! 

I don't plan to stop building receivers anytime soon.  But work does get in the way! 

When I was a teen also I worked some at a TV shop when nearly everyone's TV still used tubes, although most of the new ones were solid state.  Also when I went to college I was in a program required co-op work assignments - the first in a plant that designed and prototyped CRTs - I am glad I quickly moved on from there into RF. 

Oh yes I treasure my novice QSL cards also!  Its a wonder I got anything to radiate from my used Heath stuff I managed to get. 

CUL nice to meet you and dialog.  I hope others have enjoyed your info as well (and probably already discussed it on this group).

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.

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.

Re: Ozark Patrol Regen Receiver A+

thus far I haven't met a radio that I don't like some -- and I confess to having plenty of dead radio parts around.  hopefully no one else has this compulsion.  I wonder if anyone knows how to decode these colors that seem to label audio transformer cases? 

well my regen was my first electronics project - a P-box kit from Rat Shack.  I built it and turning the controls it made these dreadful sounds, so I presumed it didn't work.  I recently built a regen and it makes the same sounds - and works with some patience! 

while I have the parts (close enough including some Ge transistors that might still work) to build that regen again and the schematic is on-line.  I may cobble together an Ozark Patrol homebrew - and I am thinking I may also get it working on the AM BC band (with one of these loopstick coils I have) if I don't hear much on shortwave.  there are no unusual parts in that, well except those strange transistors - and I found a few!  and curiousity means I should socket the regen stage to see if other more common transistors also work (but they seem to have less capacitance in them ... hmmm ... a hint maybe).  anyway I need to do something with some of these radio parts .... but these old radio parts won't pull HCJB, Radio Nederland or Radio Australia out of the ether.  those of us old enough (unfortunately most of us) were blessed to live in a different wireless age than now.

Re: Ozark Patrol Regen Receiver A+

Hi Curt,

Let me relate my own experiences with regens. Once upon a time (when I was a kid) my parents bought me a radio kit - a regen. I was thrilled. I soon discovered that regens were just little toy radios. Not very desireable. Hard to tune. Drifty. Bump it and you'll *never* find that station again - ever. The tuning cap was a compression mica trimmer - never intended for the application! No wonder. The whole radio was made of thin plastic. Wpas and bends quite easily. It didn't stand a chance. I spent a whole winter playing with it. Then I got a better "little toy radio" - another cheapie regen. The same kind of results - maybe not quite as bad. At least it had a *real* tuning cap. But the tuning rate was lightning fast and covered many MHz i it's half of a turn. Finally I built a 6SN7 regen from the ARRL Handbook. As a kid I didn't know what to do with it but it *DID* work. So I dismissed regens as useless "little toy radios".

Later an old timer offered me his RAK-7 when I told him I wanted to receive 100 kc signals so I could examine LORAN signals. I went to his house after dark to pick it up and he had it already out on his porch. I hustled it into the car and we had a beer and a nice visit. Next day I noticed the big control prominently labeled "Regeneration". I thought I'd made an awful mistake but as long as I had it I gave it a try. Regens are *not* all created equal!! Build your regen sturdy so it doesn't flex and wobble. Use reasonable quality parts. Be realistic about tuning ranges and tuning rates. Finally, ask for some help. You'll find a lot of help available on the Yahoo regenrx group. I have - and use - two regens here with two more under construction. Everybody should have two or three samples of every kind of radio. Nobody can survive with only one radio!!

Hi Curt,

Actually there are hams who use regens coupled with a TX on the ham bands. I did a few years ago and had a lot of fun. I plan to do it some more. It's not as difficult to build a supehet with an xtal filter as it once was and so if a new ham feels up to a bit of a challenge it can be done. I built one from the ARRL Handbooks that was built and written up by Doug DeMaw. It uses four of the inexpensive color burst crystals - three in the IF filter and one for the BFO. Admittedly I had some experience by that time but mine worked the first time I powered it on. I've been lucky like that two or three times <evil grin>. Most of the time there is a bug or two. That's why we we build in stages and test each stage before moving on.

Purchasing a commercially built receiver is not a bad idea even if we do eventually build most of our own gear. One that has general coverage can be used in so many ways in addition to working on all the ham bands (MF/HF). But I would encourage anybody who has the desire to jump in and start building. So what if you let the smoke out of some parts. We *ALL* did that. That's why it's a common, inside joke :)

I am no expert in radio history, and even 'that period' where AC-1 was used was before my time (although I did own an R5 SWL receiver that may have only been paired in advertising!). I am thinking that most beginners/hams with smaller investments would use a commercial receiver with their homebrew transmitter in the 1950 - 1970 era. A decent receiver was a bit complex even with tube technology, and multiple xtals in a receiver were rather exotic except for very high end receivers.

If you want to go vintage perhaps consider building a superhet (or even a DC receiver) and outfitting it with a vintage front panel look (yes same ideal as Ozark Patrol appearance).

A local friend here is building his old novice station - and did find an SX-110. I remember some of these types of receivers having nice 'bandspread' for the ham bands to allow someone to use it after being licensed from SWL only service. But you might enjoy something with a bit more selectivity -- our bands may be a bit more crowded than 1950-something.

In spite of ARRL beginner books promoting the build of a homebrew regen, I am thinking that most folk would have taken the expense of parts toward buying a used receiver -- even the ARRL book admitted its rather high cost. The age of the regen was clearly pre-WW2.

PS - one should build a regen just for the experience! but I don't expect to plug one into my Magic Box

Hi Everyone:

I don't know what was discussed in other emails, but here "IS" just a little History:

I got my Novice  license  in the Summer of 1958.   My Novice rig was a regen receiver and a 6V6 transmitter (AC1 style) followed by a 6DQ6 built transmitter, and I did quite well.   The QRM on the Novice 80 and 40 meter bands in the 1960s was at least three to four times as bad as one has today. Also, on 40 Meters we had to deal with QRM from Radio Moscow, the BBC, Radio China etc. which are no longer around.  There maybe twice as many ham radio operaters today than were around in the 1960s, but there are not twice as many CW operators.
