NONE of the T-4X(any) had the low-pass filter on the output of the PTO. Only

If the problem is an intermittant connection somewhere (i.e. a bad solder joint) the point application of heat or cold can change the problem (either aggravate or improve) thus allowing you to isolate the
Hi Steve et al,
Well, not to make light of your situation there or anything, but I just came up
from the shack the T-4X PTO continues to sound just as smooth as silk. In
fact I'm thinking of putting the top cover back onto it using it again on the
air...
Maybe if I taunt it enough like

The best troubleshooting tool around for 'intermittent' problems. We used to be able to buy Freon
in cans that was the best and coldest, but no more. The stuff sold today isn't quite as fast, but
works. A 'tiny' Freon shot would form frost on a part!! :-)

Did you put a scope on the voltage to the PTO and watch it carefully?
As it fails?

Turned the R-4A on, with the replacement PTO from the T-4XB, and I am back to

The frequency is jumping all over, occasionally chirps, then un-chirps.
Any suggestions aside from selling it cheap?

Hi Steve,
Well, I'm almost hesitant to say this, but ever since I re-soldered that
connection of the 33-pfd. temperature compensating tubular capacitor in the PTO
of my T-4X transmitter, I have not---FINGERS CROSSED!---experienced anymore

Reminds me of a time I was too cheap to replace an intermittent board in
a garage door opener...I took it apart...took it to my office (I'm a
dentist...) and studied the solder connections under my operating
microscope...found a hairline crack...soldered it...no more
intermittent!!!...Moral?

I've been 'PTO-ing' There are no fewer than 17 variations in 4
series PTOs.!! And that does NOT take into account semiconductor changes.
MANY are merely changes in the decoupling of the DC power input

Quite true. Even if you have 20/20 vision, magnification makes it better. You
would be amazed at what you can miss without it. Also, one of the first lessons
