Any idea what the 2 that I have are worth? Not sure if they are
working of course.

Nothing like an old Wood Freeman Brass Gearbox Chaindrive....
I suspect you could build a PowerMosFET driver for one of these
without too much trouble. I wonder what Bruce @ Wood-Freeman is
using instead of Mercury Switches these days? I have seen a lot
of different AutoPilot Boxes driving Wood-Freeman Motordrives
over the years. Worked on a Model 12 last summer, for a Troller...
now that is OLD......

Know anyone who could use one circa 1981 or so? I have both the motor
drive and the control box although it is likely that some part of it
is not working since it was already replaced at the time I bought the
boat. I deinstalled the Wood-Freeman components last year to make
more room under the flybridge console. It is a 12 volt unit from a
Grand Banks 49 Classic trawler.

Haven't talked to Bruce since I sold shop 10 years ago. I did talk to Doc's
son about the four-wire motor color code I think last year. I see in their
website they have a "solid-state" driver that replaces tilting tables
"sensitive relays" and everything! Also we installed a few "solid-state
switchers" maybe 15 years ago, for the "500" when using two pump sets in
tandem. (mostly on Kodiak seiners that were lengthened to "limit" seiners) I
still have a warm and fuzzy feeling for the cast brass, manual clutch and
stainless steel chains "Iron Mike".

I gathered up two SEA-106's (I think that's the model), one with the
Eproms and one with the thumb wheels. Drew diagrams and accumulated parts to
convert the EPROM model (with freq display) to a knob tuned, all frequency
Ham rig. Was discouraged and quit when my talents couldn't figure how to
tune it in smaller than 10khz increments with SEA's decoding system for the
VCO........sigh.

With
the right incentives I might also throw in a Wood Freeman auto pilot
assembly (chain drive). It is a mechanical marvel and only weighs 50
pounds or so.


is the drivemotor 12Vdc or 32Vdc?

================================

12 volts

I believe there still is an upgrade for the mercury contactors to solid
state plug ins available somewhere. I recall we sent some out for upgrade
about 3 years ago. The boss is on vacation this week (why I am back in the
shop after retiring). I am sure he could ID the source if anyone needs them.

Hey Larry,
Thought you might be interested to know that the owner, long since retired,
of my employer, is Rodgers Jenkins, the founder of Rodgers Organ, a

They come with LSB and 10 Hz steps, not 100 or 1Khz.

Heck, that ain't nothing! My RME4350 goes 20 times further than
that....... just during warm up.

Ever thought of trying some zener diodes or solid state regulators in it to
see if stabalizes? Do is have VR type gaseous regulator tubes? It been a few
years since I peeked inside an RME.

Warmup? 4-1000's don't warmup...(c;

Oh, you mean until the graphite plates are cherry red on the pair of
them...(c;

Well, not exactly, but we did run cherry red graphites for a time on the
homebrew push-pull 211's (aka VT-127?). Shame the plate xformer smoked
during ARRL RCC certificate attempts.

Nothing like the warm glow of a pair of 3-500's key down on rtty, on a
cold
winter's night. Almost as warming as a fireplace.

And the solder running out of the 3-500 tube pins. I restored a large box of
pulled 3-500Z's back in 1970 when I arrived on Adak Island. Some of the MARS
ops at KL7AIZ were not real good about tuning the Henry 2K3 with Johnson
Viking matchbox into the 80 meter rhombic. The tubes got so hot the solder
ran out of the pins. Once I discovered the fix, there was talk of awarding
me some kind of medal!

As I remember it the 106 didn't have a divider chain that went down past
10Khz, because 100Khz was the minimum channel spacing at the time for
commercial MF/HF radios. I think Bill Forgey wanted to go to 100Hz,
but got overruled by the Marketing Guys, as it would cost to much to
impliment that into the radio. Sure made the VCO Loops, a lot easier to
design. I remember how interested those guys were to look at my Kenwood
TS-430, that I got right after they came on the market. Bill, Mark,
and Pete Hopp, did a complete Type Acceptance proceedure on it, in the
Design Lab just to see how good the design was. I saw the data, and it
would have passed on all the technical stuff, just wouldn't meet the
Operator Control Requirements. They were very impressed, and the result
was the SEA-322, which has one of the best commercial Marine Specs
around.

That is cool, Doug. There are a few Rodgers around Charleston, left by a
little dealer that started up with way too much stock, way too little
capital and way too few buyers. He left a few of them and I think he's
still coming to service them, but not sure any more. I rarely get to fix
one. Hell, any more I rarely get to fix ANY! The business has gone all
to hell. I've spent this week rebuilding a computer network for a real
estate office, cleaning the internet's excrement off their computers and
making it so copy-protected, damnable Windows XP can be force-fed, even
when it doesn't want to, so they can go about their business, unimpeded
by the billionaire from Redmond....(c;

Rodgers made nice organs, but the prices put them in the ALLEN class
without the lifetime Allen support, which also did in several more
bigshot organ companies. Allen's still got parts for their 1962
model...in stock for shipment, immediately. UNfortunately, they won't
ship them to ME to make the customers happy, trying to force them to get
service from the overloaded dealer's boy at $25 more an hour....
