Thanks for all of the comments on the vernier drive. I plan to replace the vernier drive soon. Hopefully the slightly longer leads on the neon panel lamps I recently replace will allow me to rotate

When it comes to lubricating parts in electronic equipment, I've always believed in a very small amount of lubricant and if that doesn't work, I try another small amount but typically only one

I had forgotten about the difference until recently, when I fitted one of my spares into an R-4B. The pointer was way off. I tried another one (they do look a little different from each other) that

Really?? Comparing my B line, they seem the same.? The T-4XB does have the 160m section spread out lower but that is the tuned circuits, no? I do have to tear out the vernier in my R-4B again.?

I have always used thick axle grease when re-lubing them. They DO need some friction to work properly. In any case, it should never be as hard to turn as opening a 2 l bottle. Even the Jackson Drives

Finished the VFO stabilizer's half-wave PS today.? Image below. Not much room in the underside of the TR-4Cw to shoehorn in the new components.? For connections, a 6-lug terminal strip was added to

Two places to look: See MODS.DK They have manuals from many pieces of ham stuff; radios, accessories, and antennas. Also, the Yahoo groups TOWERTALK may be a good source for antenna info. Just FYI

Good to know. ?Thank you, Jim. 73, Michael, N4KZO

Knowing what alloy and what the various diameters of the tubing that make up the eles and also the boom, and also the wall thickness, and also including any double or tripled walled sections ...then

CAREFUL! I don't know about lubing these. I have on my SB-220 those drives on the plate and load caps. NICE. But the Plate cap one was really stiff. Those drives were surplus in the 70's when

Jackson Brothers (UK) mfg and sold by Mainline Electronics makes friction type planetary reduction drives using balls for the planets STIFF or DRY Vernier Controls are usually due to dried grease.

That tilt-over with a wrench, well, make sure the person doing it is strong like bull..

Just go slowly and be careful. You will also want to take some ESD precautions. Take pictures of everything before you take is apart. 73 -Jim NU0C "Rick K8EZB" <frboswell@...> wrote: -- 73 -Jim

Hello Rob, Good to hear from you. ?I sense a 50 foot tower, non-guyed, would serve me for antenna performance and ease of use. ?I prefer not to climb, so a crank-up of some kind would be best to

Bill, M2 did not have any information on this legacy antenna, but this was a reasonable try. ?I had a response via qth.com with wind load information, but not survival wind speed. Thank you for the

I'm thinking about going ahead and replacing the vernier drive for the plate cap on my L-4B.? I got a pointer from Max-Gain for the vernier.? The new vernier seems a bit tight to me, but I've only

Jim, Thanks for the cap info. Will get an orrder in shortly. Want to do some in-circuit testing first. I am beginning to think I might actually be able to do this! Best, RB

This is the list from my Mouser project file. Note: I usually order extras beyond what I need, especially if I am near a price break. I am also attaching my log of measured values of the old caps if
