I, too, found the area around the R-4B can cap to be very tight for a big iron.
I have a 100W American Beauty that I bought for a buck at my first hamfest in
1982. It has soldered copperweld antenna wire outside in 10 degree weather and
even repaired a rear window defroster in an old Volvo
Yes...you must cover everything. I use clean shop towels slightly
wetted down then carefully remove them as to not spill filings.
This is true if drilling too.
Of course there is areas you can't cover, a powerful shop vac is the
answer here.

Hi Guys,
I have been ignoring an issue with my T-4XC until recently. When I use
the R-4C PTO to control the receiver it seems to work fine.
When I use the T-4XC PTO to control the receiver I get sort of a chirpy,
jumping around of the cw signal I am trying to copy. Both units
work fine in
Hi Bob:
Not sure you could see a slight frequency shift of a few hertz with a
scope. Unless it was accompanied by an amplitude abberation.
Does the PTO in question have the ground jumper braid to the shaft slider?
See the WB4 HFN site for info on this if not.

I know Eddy, I was going to mention your recent adventures in my opening
post.
Does it sound like the same issue your PTO had? yours was in a R-4 or
R-4A as I recall, not that it matters.
There was something about a dogbone cap in the PTO. Maybe I should go
back and read that thread, eh?

Hi Bob,
My PTO is from a T-4X transmitter...
My most recent fix to it was the complete replacement of all of the frequency
determining capacitors in it (the bad solder joints were all dispatched
earlier, one by one). I recently took to monitoring the actual PTO signal on a
separate general
Bob -
You would not be able to see a few tens of Hertz change on a scope. The
warbling of the calibrator signal is often a power supply thing, C179 on
the Calibrator board. Since it's intermittent, it's more likely a bad
ground, I'd suggest 'exercising' the Calibrator plug by moving the
You would not be able to see a few tens of Hertz change on a scope.
One method of observing small changes in frequency (and phase) is to utilize
the X-Y function on a scope to display a Lissajous pattern. I have no doubt
Garey has done this in the past. For others, one simply takes a
radio sat for 15 years on my antennas it puts out 10-40 watts all bands put on
dummy load has no output have service man.book have not opened up as of today
still has great recv. and everything else work need advice p/s is the PS7
supply was my uncles made my first contacts on and i do
Bob -
Don't be surprised that you don't see anything on the scope trace when viewing
a chirpy PTO signal. 10 Hz or even a few tens of Hz will likely not be visible
on an oscilloscope as it represents a fraction of a percent of the frequency
involved.
The usual things to check first are:
is
What are you using to measure the output? Same measurement for both
conditions?
Is there any reflected power being seen when indicating 40W to the antenna?
What is the green alc light doing when it is putting out nothing?
My TR7 will back down to 5-10W just using the output control..unlikely

Removing the PTO - at least with the A's and B's - requires removal of the

Use only dish soap for the window or you'll take off the red line!

Garey, Eddy, Paul, Curt and Steve,
Thanks for the quick replies guys. This is a great bunch on this list. I
am convinced that it is the PTO. If I lightly tap on the PTO can with a
pencil tip (and I mean very lightly) it causes the signal to jump
around. Maybe just a cold solder joint. I have

We all enjoy these rigs, Bob.
If it was me, I'd try one part at a time and hook it up to a regulated supply
and a counter. You can then log the frequency every time you walk by and see,
over time, if changing the part fixed the problem. I'd start with just the PTO
before replacing anything.
You're right, Eddy. I do prefer to remove the entire subassembly as it makes
it much easier to work on.
I can RR the front panel in about 10 minutes, I'm so used to it...

Not exactly sure about the dummy load, but the TR7 (actually all Drakes) put
