When I put up my tower last year, I refurbished a Ham-M rotator whose capacitor had gone bad. (Amazing that his 27-year old piece of equipment worked otherwise flawlessly) Rather than mess with the c

Yes! When I was diagnosing my Ham-M a year ago, I did exactly this. I found two 250 uF 50 Volt caps and connected them back-to-back. Hooking them up to the rotator, and the worked. However, these sma

Oh, I dunno. Depends on the load, and how it is arranged. My A3S barely weighs 20 lbs. K9AY and I had no trouble raising it with a Bill Wall gin pole (much more substantial than a Rohn gin pole). But

Author: aa4lr@arrl.net (Bill Coleman)
Date: Thu, 11 Jul 2002 17:32:17 -0400
You know, the problem I often have with this technique is that I cannot put the connector barrel on to the RG-213 if there's too much tinning. The coax tends to twist and distort, and I can't really

Getting the PL259 to screw over RG-8 or RG-213 sans tools is not my experience -- tinned braid or not! Although, once I get the connector on, I have little trouble soldering the four holes since I in

Yup. Rohn drawing B870725. What sort of concrete block? I'd point out that Rohn 25 really isn't intended to be self-supporting, so you are probably better off installing it according to the manufactu

If the belt uses leather -- isn't that an indication that it is worn out? Do modern climbing belts use leather at all? I bought a full harness 1.5 years ago from Champion Radio. All polymer webbing,
