Hello All,

 

I've been attracted to Frank Jones' "Super Gainer" that's in the November
1957 issue of CQ. It was his last version of that popular simple superhet
design. I've been searching the literature of the period for a couple of
years looking for a CW-AM receiver design that's actually useable on the
air, and this one comes close to being within my pay-grade as a builder. The
only thing stopping me is Frank's caution that AM performance is mediocre.

 

Would anybody have suggestions for improving its AM performance? I can email
you a .pdf of the article, if you don't have it.

 

Cheers,

 

Brian Burns

Hi Brian,
 Thank you very much for the .pdf Super Gainer article copy!
 Like you, I have always found the Super Gainer to be an interesting concept!

 My guess regarding the reason for the mediocre AM performance, would be insufficient overall gain, preceding the (second) detector stage. 
 This 1957 version includes both an RF and IF amp, as opposed to the early (1930s) versions that include neither.
 That said, the grounded grid triode RF amp wouldn't provide much gain, and the triode mixer would not provide as much gain as a pentode mixer. The older versions used regeneration in the frequency converter first stage, which may yield more overall gain than the non regenerative mixer stage, plus grounded grid RF stage, that is used in the 1957 version??

 I suspect that altering the method of switching off the crystal filter, for AM use, may improve the AM performance. Utilizing the entire IF transformer secondary winding, instead of only 1/2 of it, when receiving AM signals, would increase the signal voltage applied to the IF amp control grid.

 Another possibile improvement would be to make the IF stage regenerative. I believe that this would be easier to use, than a regenerative mixer, as the regeneration level would not change, when the receiver was tuned across the band, or switched to another band, as would be the case with a regenerative mixer.

 GL with your project, Brian!!

Hello Ron,

Thanks very much for the thoughtful reply on AM reception with the Super
Gainer.

Bill Cromwell, over on the regenerx list, uses an RAL as his ham station
receiver. It's the Navy regen from WWII, with a couple of RF stages, and
built mechanically like the battleships that it was used on. When he posts
about it, I get to wondering if it might be possible to make a modern day
equivalent as a homebrew project. 

If a regen could be built with adequate performance for use on the air as
the station receiver, it would get around the problems of finding I.F.
transformers, and coping with images and birdies. Any thoughts? I'm still
looking for a receiver project that is reasonable enough that I could
actually finish and use it (;->)...

Cheers,

Brian

Hi,

I use a regen as my station receiver, but it's solid-state. (It's one of the
Novice Station designs from ARRL, see
http://www.eham.net/ehamforum/smf/index.php/topic,90273.0.html.)

For a modern take on how to build a regen, see the articles by Charles
Kitchin, N1TEC:
http://www.arrl.org/files/file/Technology/tis/info/pdf/9811qex026.pdf.

When I get the time in future years, one of my projects is to implement a
tube version of the Kitchin designs. There's nothing all that "new" about
them, in fact they hark back to early regen designs such as using a variable
capacitor (not a potentiometer) to adjust the regenerations, and various
building tips.

There's no reason why a well-built regenerative design shouldn't be a good
station receiver, albeit a somewhat more temperamental one!

73,

Martin

Hi Brian, if you are looking for a great performing regen, may I recommend
this:-

http://www.w7ekb.com/glowbugs/rx/Regens/ZL2JJ/zl2jj_trf.htm

Undoubtedly there are other great designs, but this is one that has worked
well for me. 
I have built two and have been more than satisfied with the results. I did
not use the DC filament feature as I did not have a 9.5 volt tranny.
The key is mechanical integrity. Build it as though it were to be used on a
battleship!

Hello Martin,

~ I use a regen as my station receiver, but it's solid-state. (It's one of
the Novice Station designs from ARRL, see
http://www.eham.net/ehamforum/smf/index.php/topic,90273.0.html.)

I've been looking at regen designs for some time, mostly because I have a
friend that is a nut for them, and who keeps insisting that a regen is all I
need. He, however, is an SWL, and doesn't have to try to separate a weak
signal from a strong one that wants to take over. 

I'm a confirmed "glowbugger" as all of my ham activity was back in the
1950's, and this hobby is all about nostalgia anyway (;->)...So, I'm looking
at tube based designs.

None of the designs that I have found so far have seemed to address the
problems of overloading and pulling to a strong signal when trying to tune a
weak one. I think that one reason the RAL seems to do well under those
conditions is that it has those two RF sections with their tuned circuits
giving some up-front selectivity. I dunno--just speculating. Anyway, it's a
fascinating topic.

If anyone comes across any information on the subject, I would sure
appreciate hearing about it.

Cheers,

Brian

Hi,

I'm a member of this list, too :)

The only comment or correction I have is that my big ole regen is a RAK. 
My little ole regen is a SW-3. I have a  RAL inspired "clone" I have 
been working on hat will probably not look an awful lot like a RAK but 
I'll keep as close to the electrical design as I can. Meanwhile I'm 
making a converter to use the RAK Q5er style to get HF with the RAK. I 
like the comments and suggestions from others so far. Keep 'em coming.

I have more modern radios to use from Kenwood and Ten Tec and even the 
ARC-5 command receivers. The old regens are just plain fun and extremely 
reliable. I love to show n tell and then point at *this* computer and 
ask my guests where they think it will be in *SEVENTY or EIGHTY YEARS*!

Hi Martin, 

Here is the URL for the regenerx list---it's a yahoo group:

Thanks Bill.

Where is this "regenerative receiver" mailing list? I wasn't aware of it and
would like to join!

Hi,

I'm a member of this list, too :)

The only comment or correction I have is that my big ole regen is a RAK. 
My little ole regen is a SW-3. I have a  RAL inspired "clone" I have been
working on hat will probably not look an awful lot like a RAK but I'll keep
as close to the electrical design as I can. Meanwhile I'm making a converter
to use the RAK Q5er style to get HF with the RAK. I like the comments and
suggestions from others so far. Keep 'em coming.

I have more modern radios to use from Kenwood and Ten Tec and even the
ARC-5 command receivers. The old regens are just plain fun and extremely
reliable. I love to show n tell and then point at *this* computer and ask my
guests where they think it will be in *SEVENTY or EIGHTY YEARS*!

Hello Lorne,

~ Hi Brian, if you are looking for a great performing regen, may I recommend
this:-

http://www.w7ekb.com/glowbugs/rx/Regens/ZL2JJ/zl2jj_trf.htm

Thanks for the suggestion! I've looked at that one admiringly in the past
(:->)...It's handsomely built, and very well documented. 

Have you used it much on the air? Having done my ham operating with
receivers that were as broad as a barn door, I have become something of a
selectivity nut. I would be very interested to hear how it performs under
crowded band conditions. 

I like CW a lot, but am also planning to get on AM. Have you had any
experience with it in that mode?

~ Undoubtedly there are other great designs, but this is one that has worked
well for me. 
I have built two and have been more than satisfied with the results. I did
not use the DC filament feature as I did not have a 9.5 volt tranny.
The key is mechanical integrity. Build it as though it were to be used on a
battleship!

HBR doesn't allow attachments, so I'm sending to your email an article you
may not have seen, on National's development of the SW series, including the
SW-3. It's remarkable how important the mechanical details are.

By the way, how did you come to build two of them?

Cheers,

Brian

Sorry Bill,

I just assumed it had to be the RAL for higher frequencies since you were
using it on the air.

Cheers,

Brian

I had pondered using 6SK7's as RF amp, regenerative detector, and AF amp, followed maybe by a 6V6 for speaker use.  

Now that I have assembled a reasonable bit of test equipment, I'm starting with a single tube regen and building outward.

Message-ID: <!&!AAAAAAAAAAAYAAAAAAAAAO9WiXwKTRJMveKqmcXf97/CgAAAEAAAAPobVwXL2+ZFvq7EswhpKqEBAAAAAA==@lessonsinlutherie.com>

Hello All,

 

Many thanks for all the replies concerning the "Super Gainer".

 

After a couple of years of looking for a ham band receiver design to build,
I've decided to try coming up with a modern equivalent of the Navy RAL
regenerative. I have read so many rave reviews of the RAK-RAL series that I
figure that the old timers that designed them must have known what they were
doing. Here is a copy of my post on the "regenerx" group, and the "glowbugs"
group. Titled: RAL Challenge.

 

Anyone on the HBR list that wants to join in the fun is more than welcome.

 

I have been hearing about how wonderful the RAL is for years now, and I
think it is time to do something. We have a lot of smart and experienced
guys on Glowbugs, and on Regenerx. How about figuring out what makes it such
a terrific receiver, and coming up with some home-brewable designs that use
some of the wisdom that went into the RAL.

 

Kudos to Bill Cromwell for building his own version of the RAL!

 

I purposely said designs (plural) because I'm sure that we all have
preferences for different components, as well as differently stocked junk
boxes. I'm interested in ham band coverage of both AM and CW, so that is a
variation for sure.

 

The two bits of received wisdom that I keep hearing are two RF stages, and
mechanically heavy duty construction. I'm woefully ignorant on circuitry,
but I'm pretty good at designing and making mechanical gizmos using home
shop level equipment. And, I do a lot of three-view drawings, using
Coreldraw, which converts them readily into .pdf's for sharing.

 

Old timer hams will remember "Plumber's Delight" construction of Yagi
beams---essentially water pipe. I have been having thoughts of
"Cabinetmaker's Delight" construction for receivers and transmitters.
Plywood has some remarkable qualities for stiffness and vibration damping,
and shielding in the form of copper screening can be added easily. And did I
mention that it's just a little bit cheaper, and easier to work than
aluminum or sheet metal?

 

Anyway, what do you guys think about a group effort to advance the art of
regen design and construction by looking at what those old timers did that
was so successful?

 

Cheers,
