Per W8JI, Vaseline liquifies at just 100 Deg F...and makes for excellent fire starter. Paul's method of synthetic grease? is top notch.? It will LAST.

Cody, if you have a second TR-4 or VFO, try swapping around. I suspect that you don’t but if you can borrow one, that can help you isolate the problem. It is possible that the switch in the RV-4 is

Please define "dodgy". What exactly is it doing? Have you ruled out other components, soldering, tin whiskers, etc. ? You can often find the boards on eBay but not cheap. Better to repair if you can.

What board holds that crystal - I don’t recall. I have some spare TR7 boards and may have the crystal. Gary W0DVN

I think that shaft is 1/8 inch diameter brass rod. in Ten Tec PTO’s. I have made a few of them from brass and they worked well. I use an old Myford wood lathe, which works well with brass and

What a great resource for Drake lovers!! I’m overwhelmed by the response. I’m away from the receiver until mid next week but as soon as I get back to it and determine what frequency Drake uses for

This is why I never use Vaseline as a lubricant for anything but living things: Conents: Water (aqua), Glycerin, Stearic Acid, Isopropyl Palmitate, Glycol Stearate, Peg-100 Stearate, Mineral Oil,

Your method is really quite ingenious. I have done complete rebuild on several of these and you are right, no fun at a ll. I am fortunate to have an ultrasonic cleaner so, once I remove a PTO from a
