I knew a guy who used a 30 amp variac to feed a 5 volt, 30 amp filament
transformer on his quad driven element.Worked real good to melt the ice.

Joe,
This is a great idea but the variac can be much
I realize that one could use one smaller, but if you got a 30 amp on hand,
crank it up. I have been doing this electronics thing for 35+ years, so
familiar with turns ratio, etc.It is good to have things like variacs, like
the one I got from WA2RQY recently. Nice to put in 0-140 and get out
The quad, folded dipole and loop are the only types of antennas that I
can think of where this would work. You have a complete circuit with
them.
A dipole or beam doesn't have that unless you have a balun on them. In
that case, the current would go up the feedline to the balun and come

Hi everybody,
I recently had a DX-100 fall into my lap. Cosmetically it is immaculate
inside. Outside needs a little soap water but there are no scratches
or wear marks. AND... No hack jobs or extra holes drilled into it. It
came to me with the enclosure too.
My questions:
1 - Has anyone
Recently someone was offering DX-60 recap kits but I have not seen anyone
offer one for the DX-100. I did mine the usual way by researching the mods,
creating a parts list, and ordering them from Mouser.

Congrats on scoring a nice DX-100.
I don't know of any kits for recapping but there may be some. I've
restored two over the past few months including the one I have on the
air right now. I bought the HV caps from MOUSER electronics in Texas.
Don't expect to replace the
Hi Dave,
Ice is those clear, hard, chunky cold things that float in your glass
whenever you order-up a cocktail at your favourite drinking establishent...
Oh yes, it's also something that the Phoenix Coyotes skate on (I'll
explain later), but on a much larger scale.
It's sort of a Canadian
Back in my college days at WUVT FM, we had a 430 watt FM transmitter feeding a
2 bay horizonal polarized antenna. It was on the roof of the 7th floor of a
dorm, and the transmitter would blow a screen supply fuse if the VSWR rose too
high. So it was routine for the engineer on call (usually me

Other than the mods you spoke of, I don't know of any better ones than
those posted on the AM Window (http://www.amwindow.org/). If I were to
replace one thing, it would be that wimpy driver transformer. AES

Hi everybody,
Hi Bob,
I recently had a DX-100 fall into my lap.
My questions:
1 - Has anyone created a recap/mod
Thanks to all that responded to my question about the Viking II 122
vfo. I decided to pass on it and keep looking. I guess I could fire up
the Drake twins but nobody (including me) likes the controlled carrier.
It sure will pump the agc circuit in most receivers.
Thanks again,

the garage and stoking the wood stove every AM...Man this 65 degrees in

K4TAX addressed this issue last year with sources for the various parts(with
prices).If I can find it in my files, I will forward. I need to do that to
my DX-100B(another project).

Looks like its heading our way in the UK during the next few days, better

Yep,
That little driver xformer on the bottom of the chassis, is about 1 X

short to ground and I ended up scratching my head until I did a systematic
removal of items from the LVPS. If you don't use negative feedback
What is the Hammond/Antique Radio number/description
for the audio driver transformer for the DX 100
transmitter, if you have access to it?
Is the DX 100 audio driver transformer the same number
and model as the one for the Viking II? I have read
that the audio driver transformer is the weak link

If memory serves me John its P-T124E. This is also used in the Ranger as
well. It is a good well rounded drop in replacement.
