This seems to have morphed into some RFI stories. Here's one: I lived in Longmont, CO, until 1995. I was in a nice, middle-class neighborhood in modest houses on modest lots. I have a 50 ft tower wit

It sounds like the CW limit switch is stuck open. You can wire around the limit switch at the control head as a test (see the manual for which wires go to the limit switch and simply jumper across th
These are easy to rebuild yourself. The rebuilders will happily sell you the parts as will MFJ. If the races in the housing look good, and youre inclined, go for it. I have two in case one quit and I
This is a good point. While you can buy new ball bearings and they arent too expensive, as you disassemble it, do it in a bucket so they dont go as far. Kim N5OP "People that make music together cann
A brief note on my experiences on 75-80 m: I have K9AY receive loops, a F12 Sigma 80 OCF vertical dipole, and an inverted V with the apex at about 40 ft and the ends about 10-12 ft above the ground.
This will be challenging. You need very hard bits (real cobalt bits, not just the gold colored ones), plenty of cutting oil, patience (because youll have to go slow), and lots of stamina (because as

Would you mind being a bit more detailed about this? What it is, exactly, and how you manage it? I think I know, but I want to be certain. Also, if there's a permanently-installed a safety line on a

I have a genuine pre-MFJ Cushcraft 40-CD2. The loading cools on it are covers in heat-shrink. Kim N5OP "People that make music together cannot be enemies, at least as long as the music lasts." -- Pau
Ive seen sites where someone improved on the original design with high-Q coils and it looks enticing, but I recall that it wasnt trivial because the distribute capacitance also changed, which led to
I have a F12 Sigma 80 antenna, which is an OCF vertical dipole with inductive loading at the feed point and a hairpin match. While it *requires* a common-mode choke at the feed point, it works very w

Yeah, it's probably the best built antenna I've seen short of towers as antennas. It's quite heavy, too. I can see why you chose to not schlep it back to the States. I hope it's serving the local clu
I looked on eHam reviews, and saw someone, using an autotuner at the antennas happily report that the SWR was essentially 1:1 on every band. My though was"I should hope so; otherwise, your autotuner
I have a Green Heron RT-21 and its wonderful. Ive also had a HyGsin on troller with a Rotor-EZ modification. While the Rotor-EZ is a magnificent improvement, the RT-21 blows it away. Kim N5OP "People

When I lived in Longmont, CO, in a 1200 sq ft house with lots to match. I had an HDBX-48 with a KLM KT-34A and a Cushcraft 40-CD2 all rotated by a T2X. I was stunned that when I gave directions to se
