[Drakelist] T-4X PTO - The DARNDEST Thing!

2011-08-17 Thread Eddy Swynar
Hi Guys, Well, the PTO went back to its nasty old habit of ...wobbulating in very short order after I *thought* that I'd remedied it (per note below)---and so I carted the T-4X upstairs to our kitchen table (yes-yes, right AFTER the XYL left to do some shopping this afternoon!)... AMAZING the

Eddy - Yep, solder is the #2 problem in PTOs. The white tubular caps (glass or ceramic tube w/ wire wrapped around each end) are almost all selected. I have seen some where the 90 pF 'base' cap is also of that type, just considerably larger. If there is Black paint on the end 'outboard' of

Hi Gang, Early this morning I removed the shield cover from the PTO of my Drake T-4X transmitter, listened to its raspy / wobbly signal on my nearby Yaesu FT-980 transceiver... I then pulled the power plug of the thing, looked at the solder connections of the small white tubular temperature

Well doing the re soldering fixed the frequency jumping in my R-4C PTO. That was about a year ago. No problems since. Terry, W8NJR In a message dated 8/15/2011 1:40:27 P.M. Eastern Daylight Time, deswy...@xplornet.ca writes: Hi Gang, Early this morning I removed the shield cover
