I've seen CuO rectifiers from before WW2.  Come to think of it, I've
seen a datasheet for a CuO FET from (I think) before WW2 -- French, 
as far as I remember.  Just saw it once and remember very little about
it... does this ring any bells anywhere else?

I'll say this for Icom, their field service organization is first rate.
*If* they can get the parts, they do quick, courteous, and competent
repair work. When my beloved IC211 was terminated by a direct lightning
hit, they tried very hard to repair it, but couldn't get the custom
chips. They very kindly UPSed the carcass back to me, *NO CHARGE*.
That's the mark of a class act. I'll be shopping for 211 guts at
Dayton.

This is very true. Unfortunately, it was US companies falling down on
the job of consumer satisfaction in the first place that lost them their
market share. The arrogance of GM and Ford zone offices is legendary,
we won't even mention their ripoff dealers. And GE, don't get me started 
on GE. They won't even sell you parts for something they *still* make! 
I don't even want GE *light bulbs* in my house. The class acts of American 
companies are exemplified by Tektronix and HP. I've got a HP45 that I bought 
in 1966 that HP *still* does *warrantee* service on. They replaced the ENTER 
key on mine last year, *NO CHARGE*. Now that's class. I just bought a HP95
instead of a Wizard *because* of the extraordinary service HP has offered
me in the past. When Tektronix finally decided to quit supporting the
453A last year, they shipped all remaining stocks of parts to the *retired*
engineer who designed the scope and refer customers to him. That earns
him a little extra money in retirement, and keeps us 453 owners happy.
That's class. My company just bought several new Tek scopes partially
because they are excellent scopes, and partially because of the class
way Tektronix looks after their old friends.

Are you still living in the late 80's?  There's BEEN an international standard
for 9600 baud modems for over 2 years now (CCITT v.32).  To top it off, the   
NEW standard is for CCITT v.32bis - 14.4 kbaud - and you can get a good       
external model for $290 - $300, NOT $500.

You might consider finding out a little more about what's happening today
before making assumptions like the one you made.

Hey there,

Is there anyone who knows something about the availability of SC-1080
VHF Power Amplifier Module. One friend of mine just blew the 145 MHz
power stage of his IC-32AT hand radio.

There is a Mitsubishi logo in the module though the type number SC-1080
is probably a one of Icom's.

If you know where one could get the module or what is a suitable
replacement part, please inform me. My friend doesn't have access to
Internet. We are also curious of knowing the price of the device.

Thanks,

When I first became interested in hamming back in the 60's, Heath had a rig on
the market called the "Benton Harbor Lunch Box".  The only thing I remember 
about it is it's general size and shape, and that as a teenager I found the rig
fascinating.  Are there any OT's out there that can refresh my memory on this
pre-HT dinosaur?  What freqs and power ranges did it have?  Has anyone seen any
at Hamfests?  What are they selling for?  How well do they work?

It's not as easy as you think.  Many of the IC's are custom, built 
specifically for ICOM, and the production lines for these IC"s have
long since shut down.  Hauling out the old tooling and starting up
a fresh batch of an obsolete IC (which the military does quite frequently)
costs big $$$$.  Are you willing to pay $200 for a new chip for a
$300 radio? 

I didn't think so.

The alternative would be for the manufacturer to buy an oversupply
of the IC's while they were still in production.  Perhaps 1 extra
IC for every two sold in radios.  But guess what... as usual, we
consumers will end up paying for it in higher new equipment prices.

Not many IC's have a production life of more than 7 years.  Memories
IC's are even shorter.  The military, for example, sometimes has to
take Megabit DRAM chips and place them in 64Kbit ram packages, wasting
the extra capacity.  The alternative (replacing the system they go
into) is just far too expensive, even for them.

The real solution to this problem is for the manufacturers to stop
using custom IC's and instead use off-the-shelf components.  At least
there would be some hope of getting replacement parts in the future,
even if out of an old toaster oven :-).  But, alas, it is still too
expensive to use a separate CPU and EPROM when a mask programmed
CPU+PROM chip is cheaper....  Like it or not, that's the way things
are going to stay...

Money and patience.  The markup on new ham gear is minuscule; about 15%, 
compared to almost 100% on most other hard goods like tv sets, etc.  
Consignment dealers in used rigs usually get a 25% commission, but have to 
put up with consigner's wildly inflated estimates of the value of their 
used rigs, leading to slow turn-over.  A friend of mine runs a ham store, 
and is always teetering on the brink of financial disaster.  The 800- 
number mail order places are selling the new rigs for just a few dollars 
over their cost, making their profit on volume.  No local retail dealer 
can ever hope to match their prices; in many cases, the mail order price 
is actually below a local retailers *cost* on the rig.  My take is that it 
is virtually impossible to make money selling ham radio gear.  Having said 
all that, I wish you the best of luck. I too am frequently put off by rude 
dealers;  a clerk at a store where I've spent well over $5,000 on ham gear 
in the last year literally laughed in my face and told me to get lost when 
I made him an offer on a piece of used gear.  All too often, ham stores 
are staffed by your typical ham weenie, who knows nothing about retail or 
the concept of customer service.  If you can find a formula for good 
service and low prices, the ham world will beat a path to your door.  Good 
luck...

Well, in the U.S. the waiting period for a Ham liecense is around 5 to 6

Watch out here.  Unless the signals are generated INSIDE the hand-

Unwanted or unlawful signals originating outside the receiver are
more accurately called spurious emissions or interferrence from the
lamps.  Just wanted to clear the air.  Flame resistant suit on.

What about the HW101? The first time I helped assemble one, we did it
without looking at the circuit diagram. Started at 10pm, and had the
first contact about 7am. The set is still working, after 13(?) years.
The only parts which needed replacement were the final tubes, after
many years of service, and at higher than recommended voltages! The
later models of the HW101 were solid-state by the way, except for the
finals.

Ron -

If you wouldn't mind rerouting this for me . . . 

The first true semiconductor diodes, in the 1N21/1N22 style
cartridge mounting, were a British development ca. 1940,
for use as point-contact silicon mixers in early S-band radars.
The British divulged design info to us, and the US-improved
design went into use shortly afterward.

The numbers 1N21, 1N22, 1N23, et al. would have been assigned
by the Radio Manufacturers' Association ca. 1942-43.
(The numbering plan began at 21.)  Western Electric and Sylvania
made a truckload of these units, under the 1N21A, 1N21B, etc.
variants, during the war.  By contrast, the well known 1N34
germanium unit wasn't introduced (by Sylvania) until Feb. 1946
(via an ad in "Electronics").

I believe Ohl was actually a Bell Labs person, at least
in later life (Fifties).  He published several papers
in the Bell System Technical Journal between 1947 and 1959.

The '38 date is way too early.  The British wartime origins
are well documented in a (British) book that I have
("From Metres to Microwaves").

The reason I'm so dxxn smart about this is that a Japanese
collector asked essentially the same question a month ago!
