One issue to keep in mind is that vintage military crystal ovens were
intended to keep the crystal at a ROUGHLY fixed temperature over an
extreme range of environmental conditions -- say from 'unheated
shelter north of the Arctic Circle, winter conditions' (or 'unheated
bomber at 24,000 ft.') to 'noonday direct sun, Libyan desert.' If the
crystal harmonics were within a kc or two over the entire range, that
was okay, even if you could hear the frequency going up and down as
the oven cycled on and off.

That won't work for SSB and it would make some of us crazy. The
simplest possibility is the always-on resistor heating source: Our
ambient temp extremes are likely to be more like 60-80 degrees F, with
most of the time being 68-73 or so, so a fairly quick warm up to any
temp above normal internal set temps will work fine. You just choose a
resistor that gives you about the right final temp. 1/4 watt
dissipation might be the right ballpark for the small octal-base
plug-in military ovens.

A better answer (much faster stabilization) is proportional control of
the oven heating so that the heater power decreases gradually as the
oven reaches the desired temperature. This is easy to do using a power
FET and a thermistor and the result will easily fit any of the usual
ovens.

Because they must be hotter than any possible internal equipment temp,
the set temps of military ovens are high enough to gradually destroy
the usual oven materials (Bakelite, etc.) but for ham use 120-140
degrees is generally high enough. If you bring out the thermistor
connections to the oven base and calibrate it accurately around the
desired temp before assembling then you can measure the oven internal
temp to confirm that it's working.

The usual thermistor is a negative temp coefficient resistor. You put
it in a voltage divider so that it reduces the forward gate bias on
the FET as it warms up. The other arm of the divider is chosen so the
FET will be biased 'on' at room temp. Put a small power resistor with
a value chosen to dissipate 1/2 to 1 watt in the drain circuit. It may
be necessary to play with arrangements to get the loop gain right:
thermistor mounted in free air vs. clamped or glued to the crystal and
heater, etc., but I remember these circuits as being almost NO trouble
to get working.

Both the FET and the power resistor in the drain are heaters.  Clamp
them to the case or chassis of the oven -- typically a piece of copper
with the crystal clamped on the other side.

The heater resistor must be stable at full wattage over years.
Wirewound or (better) metal oxide resistors are suitable. Must be
sure the thermistor doesn't dissipate enough heat at the applied
voltage to substantially affect its own temp.

Obviously this is a DC circuit but poorly filtered or even pulsating
DC should be fine. Very little power is required -- a watt, probably,
at most, during early warm-up, in the usual small plug-in oven.

Thank you for a great reply and invaluable information. I will be building 
the oven with closed loop control. When I get it built and calibrated, I 
will forward the schematic and or pictures when completed. .

I finally got around to posting some more pictures to the website: Tony WV3Z, Tom KC9KEP, Roger KB2ZXY, Tom K7PJT, and my "new" HBR-11. Please check them out and if you want me to add more or I forgot someone, please tell me. The website is much better than before but it still has problems with large X-MB pictures (fantastic detail) because it takes up too much space. If you can hold them to <250KB each, that would be great. If not, I have to reduce them in size and that doesn't always turn out well. If you can reduce them some and resend them to me, that would be great.

Message-ID: <4A722753.8010601@iscweb.com>

My e-book on "The HBR Adventure", started some 3 years ago, has finally 
been completed, and is now available to those having interest in the 
way-back-then people, amateur radio home-brew, as well as the past and 
present technology of the Crosby HBR double superheterodyne hot-cathode 
receiver designs.  For a more detailed book description and 
how-to-order-details, go to www.w6hht.com.

This ordering window will be open until August 31st.  Orders will be 
batched, produced in runs of 20 - 30 e-books until all the orders are 
filled and shipped.  The next ordering window will occur in November so 
as to make the book available for Christmas.

I have no intention to create an inventory of books for sale, but rather 
to operate a process by which books will be produced and shipped to 
specific order.  That process, run in 2 cycles during 2009, may be 
repeated in 2010, depending upon interest in the book.

Most unexpectedly, and coincident with opening the ordering window, I 
find I must change my web host for www.w6hht.com.  Within the next ten 
days, there is probability that my web page may go down as the domain 
registry shifts from one registrar to another.  This interruption should 
be brief; its timing and duration is far beyond my span of control.

If/when www.w6hht.com does go off the air, it does not mean I have left 
the planet and taken the e-books with me.  Please be patient, "stay 
tuned", and www.w6hht.com will shortly thereafter re-appear (along with 
the HBR e-books!) supported by a different (and much more caring) web host.

If you wish to order the book while my web site is down, contact me 
directly at w6hht at arrl.net and I can provide you with ordering forms and 
information by e-mail.

This e-mail is a general notification to members of the HBR forum 
visiting this web page, and is not a solicitation to anyone.  If you 
wish to discuss the book with me, please do so direct at 
w6hht at arrl.net.  I will not respond to any book inquiries made on this 
forum.

Subject: [HBR] Recollections of a Radio Receiver
Message-ID: <cf1.59c5f950.37a475c4@aol.com>

I have been working with Jay for the past few years on
his book.  Jay knew Ted Crosby personally and felt
that the HBR adventure should not fade away.  The
book is a treasure trove of information relating to 
the HBR's and how to build them as well as other
information relating to building vacuum tube receivers.
It also delves into the personality of Ted Crosby and
his inner circle.
 
It started out to be a paper bound book.  As the pages
started adding up, Jay came to a fork in the road to
delete some information to keep the book a reasonable
size.  This meant deleting some relevant information.
In discussions with me and Lee, WB6SSW, he made
the decision to go to a CD so that all the information
could be retained.  It is now in the vicinity of 500
pages of information.  The pages are all in PDF
files and easy to print out.
 
There is a lot of information that has not been published
before as well as information from a lot of sources
that is compiled in one CD.
 
Having this CD is like having an old Handbook but
it is just vacuum tube receivers of the Ted Crosby
design.
 
This book is not going to make Jay rich and he
never will be compensated for the time he put
into the writing and editing that he has done.
I hope there is enough support from this group
that will have made his efforts worthwhile.
 
The website is _www.w6hht.com_ (http://www.w6hht.com) .  I have no financial
interest in this project.

Jay,
Definitely sign me up for one of those HBR-CDs (and I encourage others to do the same)  .....sounds like an excellent and thorough job.

Wow - I wish I'd known - I have one of the spec-sheets from the recommended 
variable cap - it would have fit a nice niche' under components.

I certainly am interested, just wish there was an easier method (Paypal?) of sending money overseas....
