How's about a 6BA7?

6BA7 is somewhat noisey. These were used in the 75A4. A typical modification on the 'A4 is to reconfigure the 1st mixer to a 6ES8 dual triode configured as a Pullen Mixer. Better intermodulation distortion performance and less noise. My HBR has this setup and works well.

Every once in a while I receive some really great HBR email from someone who came across the website. I just received this note from Tom Rousseau and thought I would share it with the group. Just goes to show more of the history of these units and how they were appreciated. I often wondered where a unit like Bill McKay's ended up. I'll post the pictures to the website later.

--------------------------------------------------------------------
Hi Kees,<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
I was recently surfing the internet when I came across my photo on your website.  So I thought I?d send you a note to let you know that I am still alive and well.  I am the HBR-16 featured on the opening page on your very fine HBR website.  I was very lovingly built by Bill McKay, W7QBR, in the early sixties.
 
The attached photos show my current status.  A little older looking and a bit more worn, but still not bad for being nearly fifty years old.  I am still all here, with all my coils, storage drawer, and even the three-ring notebook with Bill?s design/construction notes.  I attended Washington State University with Bill while he was studying EE in Pullman.  I even operated CW Sweepstakes one cold November with Bill and Wes, W7ZOI, from Bill?s college room.  I enjoyed the active on-the-air life, and the considerable attention that Bill always seemed to find time to give me.  He liked to use me on the air, but I think he more enjoyed tinkering with my insides, improving my performance.  He was not happy with my excessive birdies, and was trying to reduce them.  The most notable modification was when he changed my product detector from a 6BE6 to a 7360.  I think that he was trying to get lower distortion.
 
Eventually, I think that he tired of me.  He sold me to a college mate, Linley Gumm, K7HFD.  He needed the money to fund his next HBR.  I guess Bill did, indeed, make a couple of more HBRs, but I never had the chance to meet them and do a side-by-side operation with them.  Linley took good care of me, but he mostly kept me stored in a safe, dark place in his garage, together with my coils and design notes.  Linley was too busy with his career and family to give me much attention.  Linley was one of Tektronix? very top design engineers, leading the design of many forward looking spectrum analyzers.
 
By the early nineties, Linley realized that he probably wasn?t going to use me, and he wanted the space in his garage.  So he gave me to a Tek work associate of his, Tom Rousseau, K7PJT.  I have been living at Tom?s ever since.  At first, Tom carefully brought me up with a Variac, then we toured some of the bands together.  It really felt good to have that warm glow back, and the sensuous feeling of changing coils as we cruised the different bands.  And wow, to have those microvolts entering my antenna terminals and flowing though my vacuum circuits was an incredible feeling that I had long ago forgotten!  Tom cleaned my switch contacts and potentiometers, almost with the same love that Bill used to afford me.  He took notes of things that he wanted to do to return me to original operating condition.  He noticed my 7360, and made a note to return it to Ted?s original design;  but later he decided to leave it alone when he found out that it was an authentic W7QBR mod.
 
I am hopeful that I will again have a functional life at Tom?s QTH, operating alongside one of his vintage homebrew transmitters.  However, after our few weeks together, he disconnected me and put me on a shelf with many other radios, some of which are also homebrew, but many are Hallicrafters, Nationals and Hammarlunds.  I like the companionship provided by my commercial friends, but feel just a little apart from them, nonetheless.  I have been here for more than 15 years, and am still looking forward to another opportunity to feel the warmth of my tubes.
 
Anyway, thank you for so nicely displaying my photos and history on your website.  And thank you for allowing me to see all my cousins and the great levels of achievement that they aspired to.  Let?s keep in touch.  I?ll let you know when I?m on the air again.
 
73,  W7QBR?s HBR-16
 
BTW:  I want to thank Wes W7ZOI, Linley K7HFD and Tom K7PJT for helping me to remember my history and taking good care of me for these many years.  It is indeed a frightening thought to consider what might have happened with less understanding hams;  I could have been parted out for my beautiful dial or IF transformers!

Kool!!!  I always wondered what happened to McKay's HBR-16; it has to the
most recognized HBRs out there!
It is comforting to know it still exists and is still in good condition; and
owned by someone who appreciates the
history behind that set.

Subject: [HBR] HBR-16 Coils
Message-ID: <199068.44514.qm@web30902.mail.mud.yahoo.com>


Just getting ready to wind the 80 meter coils for my HBR-16 project and had a question about the location of the taps.

Specificaly on L1 and L2A the tap is located at 28 1/2 turns from the "cold end", which I interpret as the start of the coil at pin #2, this causes the tap to fall in the area where the 2 turns are spaced over 1/4".

Just wondering if I have interpeted the coil winding instructions correctly.

Also on L3 the tap is at 15 1/4 turns on a 15 1/2 turn coil, this places the tap a mere 1/4 turn from the finish or "hot" end of the coil, is this correct?

Thanks,

Tony WV3Z

Tony, having just wound some 80 meter coils for the HBR 12, I can assure you 
that you are reading the instructions correctly. As per Ted origional 
instructions, drill a 1/8" hole where the tap should be and tap into the 
winding at that location.
I am looking at my coils now and yes, L3 is tapped a mere 1/4 turn from the 
end.
Hope this helps.

That was a wonderful post. The old timer friends of my dad, W1KPS (SK) were
engineers from Ratheon, Mitre Corp and MIT and always had a unusual kinship
with anyone else interested in homebrew tube gear. Like them, Mr McKay must
have been a rare treat to know and a wonderful resource...like most of you
fellas.

I consider my self a very average builder. Strangely, I use a lot of
information from the solid state book Experimental Methods in RF Design by
W7ZOI to design IF filters, bandpass filters, IF coils, etc. for my tube
receivers. I did not know Wes Hayward was associated with the HBR receivers.

I apolgize for non-HBR series posts but if not here there are not many other
alternatives.

6BA7 is somewhat noisey. These were used in the 75A4. A typical modification
on the 'A4 is to reconfigure the 1st mixer to a 6ES8 dual triode configured
as a Pullen Mixer. Better intermodulation distortion performance and less
noise. My HBR has this setup and works well.

How's about a 6BA7?

Every once in a while I receive some really great HBR email from someone who
came across the website. I just received this note from Tom Rousseau and
thought I would share it with the group. Just goes to show more of the
history of these units and how they were appreciated. I often wondered where
a unit like Bill McKay's ended up. I'll post the pictures to the website
later.

Hi Kees,<?xml:namespace prefix = o ns =
"urn:schemas-microsoft-com:office:office" />
I was recently surfing the internet when I came across my photo on your
website.  So I thought I?d send you a note to let you know that I am still
alive and well.  I am the HBR-16 featured on the opening page on your very
fine HBR website.  I was very lovingly built by Bill McKay, W7QBR, in the
early sixties.
 
The attached photos show my current status.  A little older looking and a
bit more worn, but still not bad for being nearly fifty years old.  I am
still all here, with all my coils, storage drawer, and even the three-ring
notebook with Bill?s design/construction notes.  I attended Washington State
University with Bill while he was studying EE in Pullman.  I even operated
CW Sweepstakes one cold November with Bill and Wes, W7ZOI, from Bill?s
college room.  I enjoyed the active on-the-air life, and the considerable
attention that Bill always seemed to find time to give me.  He liked to use
me on the air, but I think he more enjoyed tinkering with my insides,
improving my performance.  He was not happy with my excessive birdies, and
was trying to reduce them.  The most notable modification was when he
changed my product detector from a 6BE6 to a 7360.  I think that he was
trying to get lower distortion.
 
Eventually, I think that he tired of me.  He sold me to a college mate,
Linley Gumm, K7HFD.  He needed the money to fund his next HBR.  I guess Bill
did, indeed, make a couple of more HBRs, but I never had the chance to meet
them and do a side-by-side operation with them.  Linley took good care of
me, but he mostly kept me stored in a safe, dark place in his garage,
together with my coils and design notes.  Linley was too busy with his
career and family to give me much attention.  Linley was one of Tektronix?
very top design engineers, leading the design of many forward looking
spectrum analyzers.
 
By the early nineties, Linley realized that he probably wasn?t going to use
me, and he wanted the space in his garage.  So he gave me to a Tek work
associate of his, Tom Rousseau, K7PJT.  I have been living at Tom?s ever
since.  At first, Tom carefully brought me up with a Variac, then we toured
some of the bands together.  It really felt good to have that warm glow
back, and the sensuous feeling of changing coils as we cruised the different
bands.  And wow, to have those microvolts entering my antenna terminals and
flowing though my vacuum circuits was an incredible feeling that I had long
ago forgotten!  Tom cleaned my switch contacts and potentiometers, almost
with the same love that Bill used to afford me.  He took notes of things
that he wanted to do to return me to original operating condition.  He
noticed my 7360, and made a note to return it to Ted?s original design;  but
later he decided to leave it alone when he found out that it was an
authentic W7QBR mod.
 
I am hopeful that I will again have a functional life at Tom?s QTH,
operating alongside one of his vintage homebrew transmitters.  However,
after our few weeks together, he disconnected me and put me on a shelf with
many other radios, some of which are also homebrew, but many are
Hallicrafters, Nationals and Hammarlunds.  I like the companionship provided
by my commercial friends, but feel just a little apart from them,
nonetheless.  I have been here for more than 15 years, and am still looking
forward to another opportunity to feel the warmth of my tubes.
 
Anyway, thank you for so nicely displaying my photos and history on your
website.  And thank you for allowing me to see all my cousins and the great
levels of achievement that they aspired to.  Let?s keep in touch.  I?ll let
you know when I?m on the air again.
 
73,  W7QBR?s HBR-16
 
BTW:  I want to thank Wes W7ZOI, Linley K7HFD and Tom K7PJT for helping me
to remember my history and taking good care of me for these many years.  It
is indeed a frightening thought to consider what might have happened with
less understanding hams;  I could have been parted out for my beautiful dial
or IF transformers!

Kool!!!  I always wondered what happened to McKay's HBR-16; it has to the
most recognized HBRs out there!
It is comforting to know it still exists and is still in good condition; and
owned by someone who appreciates the
history behind that set.

Message-ID: <3123.69.95.236.25.1239051630.squirrel@newmail.core.com>



Hello all!

Is there a reason that I have not located 160m coil
winding instruction for the HBR-11?

Is it that the L/C ratio
would be too high for 160m or have I just not sucessfully located said
instructions yet?

it doesn't seem that it would be too
difficult to do?

Thanks!

It might work. I've thought of giving it a stab. But.....160 meters is 
awfully close to the 1st IF frequency.

I'd guess the problem would be not having enough capacitance range to fully
tune the 160 meter band with one set of coils. It would easy to run the
numbers with an online LC calculator to see how much coverage could be had.
Using high side LO injection would help on the OSC side.

I thought of winding a set, myself.... the the wire would end up being 
PRETTY DARNED SMALL with the capacity for enough turns*... not to mention 
the possibility of interaction with the 1st. IF.

*(it would put you quite a ways from the doorknob - HI HI HI )

Hello
all,
?
I found a comment
made by Ted Crosby in his HBR-13 QST feature:
?
"Often,
I&rsquo;m queried about font-end coils for the broadcast and 160-meter
bands.? Sorry, but these are
impracticable; the range of the tuning capacity too small for the required
frequency coverage at these relatively low frequencies.? Also, in both instances the
frequencies are too close to the receiver&rsquo;s first i.f. for
trouble-free operation."
?
As suspected
:-(

Subject: [HBR] 160m coils for HBR-11?
Message-ID: <d0d.4f7d09f2.370f74a2@aol.com>



Big Nick,

The Hallicrafters SX-100 and early SX-101's had a  1650 Kc 1st IF and 
covered 160 Meters.  As for the tuning capacitance being  too small, the ratio of 
Fmax to Fmin on 160 is less than on 80  meters.

Yes, you would have to watch the winding capacitance.  How  about using 
powered iron toroids so that fewer turns are needed.  I have  been tempted to 
try this with the HBR anyway.  The Q would be at least as  high as the air 
wound coils -- around 200 or so.  Hope Ted doesn't mind me  suggesting that.  
Another option may be to use universal wound  coils that could be modified 
by unwinding to the required inductance.   Possible candidates would be old 
IF transformers or BC  coils.

73,

Dan K9WEK

Hello

I found a comment
made by Ted  Crosby in his HBR-13 QST feature:

"Often,
I&rsquo;m queried  about font-end coils for the broadcast and 160-meter
bands.  Sorry, but  these are
impracticable; the range of the tuning capacity too small for the  required
frequency coverage at these relatively low frequencies.  Also,  in both

trouble-free operation."

As  suspected
:-(

Try it!  That's the fun of having homebrew gear, right? 

Can you imagine the outrage on the Collins reflector if someone suggest 
they were going to try to convert their 75-A4 to cover the broadcast band?  

Right now, I'd about kill for a bunch of Amphenol octal base coil forms so 
that I could play with expanding the coverage of my HBR-16 and trying out a 
Harley 1st oscillator.

Hmm .. Good food for thought!

I can wind universal coils:?

As a mater of fact, I made my own BFO tapped coil with my coil
winder for my HBR-11.

I may just try this regardless of what

Message-ID: <002401c9b9ed$5bd197a0$da21334a@COMPAQ>

Happy Easter All,

At the request of at least a couple of readers, I've updated my flickr.com website with a hand-drawn schematic diagram of my add-on RF pre-selector / frequency standard, for use in OT BA receivers like the AR-88...

It may be crude, but (hopefully) it's effective!

To see it, just click onto:

Message-ID: <010001c9bd35$91229990$2321334a@COMPAQ>

Good Day,

Wow, and DOUBLE wow...!

I did some research through my 1971 edition of the "Sylvania Receiving Tube Manual", in a quest for possible "hotter" tube substitutes for the 6DK6 that I placed inside my recently homebrewed AR-88LF pre-selector: 

http://www.flickr.com/photos/15888272 at N05/?saved=1

I found several with the same pin-outs as the 6DK6, but by far, *THE* hottest candidate appeared to be the 6JK6 (almost TWICE the transconductance / mu of the former)...and, as GOOD luck would have it, ye olde junque box yielded a "primo", NIB Sylvania-brand 6JK6. 

I''ve just finished installing it inside the pre-selector, and as I said earlier, wow and DOUBLE wow...! This thing is REALLY smokin' now --- indeed, on the lower frequencies, I have to retard the pre-selector's RF gain somewhat to keep it from "taking off".

But what a minor inconvenience, when compared to the tremendous and VERY worthwhile improvement this small tube has afforded the rig's overall sensitivity...

If you're at all contemplating the construction of a pre-selector for YOUR BA receiver, do consider acquiring a supply of the 6JK6 tube --- I don't think you'll regret your decision!

Iowa History museum in Cedar Rapids as well. Kolona, IA is home of the Amish

Hi Eddy, There will be the a nice hamfest/ARRL convention in South Sioux
City NE on the week end of April 18 i think,.,.,  APRIL 17-18 2009
google "3900 club" for the details.    From Ida Grove go north on 19 (i
think) to US 20 then west about 45 miles or so to Sioux City, dont go to
soo city but stay on 20, across the river (Missouri)
go north at the so soo exit and head for the Marina Inn which is on the
south side of the river.  Then find the organizer, Tom and say howdy for
me.
I am usually there but this year it is too early in the year.   (this is
my home area and used to know people in Ida Grove and family in
Holstein)'

Ida Grove is pretty much the "West Coast" of Iowa, most of the
interesting (IMHO, because I grew up there!) stuff is closer to the East Coast.
Collins in Cedar Rapids is definitely a 4-5 hour trip each way from the West
Coast but worth it.

The big regional hamfest from an Eastern Iowa perspective is in Peoria, IL
in September, smaller ones are also usually held in later summer/fall.

Peoria is a long way away from Ida Gove.
You probably want to ask someone who knows more about
Sioux City, Sioux Falls and Omaha.

Tim.

I've lived in Kalona, IA and it's a pretty nice community.
Check with the Muscatine, IA ham club - I don't know if they have
an event going on this spring or not but they might know of others.
The ARRL/QST might be able to tell you, too.

Hi All,

This note is for all of you stalwart, die-hard 75-meters AM buffs...

You'll be happy to know that some of your signals are making it across the Atlantic, all the way to the QTH of John (GM7NVA) --- and in VERY FB fashion, too, no less...

***************************************************************

"...The '88' was on all last night (8pm - 4am) listening to some truly amazing signals off a group of USA 'AM' stations, just above 3.8 mHz. The band was in good shape and the '88' (on a K9AY loop) sucked up the strong signals like a dream. Turning back the RF and turning full on the AF made the signals sound like big broadcasters on a dead band with no qrn/m. No sunspots have brought around some very unique lo-band conditions. Even 160 was a treat here with some strong SSB."

****************************************************************

Many thanks to all on 75-meters AM last night who helped make John's foray onto the band with his RCA AR-88 a rather memorable one...!
