My standard approach to troubleshooting KT-34 issues: Connect a dc ohmmeter between the 10 meter and 15 meter trap capacitor outer tubes on each element half. After correcting for ohmmeter lead resis

I concur with VE4XT's assessments that the open wire feedline is probably the RFI culprit, and that the vertical's performance is likely to be inferior to your dipole at 60'. Also, verticals near a h

My XM240 is six feet above a KT-34XA. The booms are aligned. It works for me. After you get the antennas installed, run a f/b ratio test on the tribander. Front-to-back ratio is easy to measure, and
I have to apologize for my previous posting on this subject that said I had an XM240 6 feet above a KT-34XA. My 40 Meter antenna is the 40-2CD, not the XM240. I got the model numbers mixed up. Sorry

Maybe when you cut it, the copper mashed down so you couldn't see the steel core. Try scraping off the copper with a knife. Measure the diameter before and after with a micrometer or even a machinist
Harbor Freight Tools currently has on sale a 700-watt 2-cycle portable generator, weighs 38 pounds (no worse than, e.g., a prop pitch). I do not recommend this generator. I bought one of these in 201
I have done this at 100 watts, with a dinky little panel-mounted toggle switch. You could probably use a wall switch or a relay at high power. I have used a 3-way wall switch to make a 2-position ant

For contesters/DX'ers, 2 dB on TX/RX on 5 bands is to kill for. Dave Hachadorian, K6LL Yuma, AZ OK folks, now a word from our grinch: I cant imagine spending all that money to put that complicated an
For small quantity purchases, Arrow Electronics has reasonable prices. For example: 2631803802 2.4" cores $4.83 (backordered to May 4). 0431177081 big clamp-ons $11.03, in stock. Those prices are plu
I got some of those short-saddle ones from Hill Radio one time when I ordered the Rohn part number. I didn't like them either. Recently I got some from Texas Towers, and they have deep saddles. I don
That is an interesting catalog: http://www.sitepro1.com/resources/pdf/13catalog.pdf Relating to a previous discussion on the reflector about cable clamps, they have some nice-looking ones on page 153
The wench looks a little rough, but I'm glad to hear that she's in good physical condition. Just give her a coat of Rustoleum, and she'll be good to go! Dave Hachadorian, K6LL Yuma, AZ http://sfbay.c
On my Dutton-Lainson B1200 brake winch, if you are below minimum load, the handle actually unscrews and comes off in your hand. Since this is obviously not a good thing to do, just apply a little tug
I think you'll be ok. The XM240 has a broad resonance around 18 MHz, but doesn't seem to affect 10, 15, or 20. I have a KT-34XA 6' below an XM240, and I do ok on the tribander bands. Dave Hachadorian
While we are talking about masts, let me just mention one approach. 38 years ago I had Texas Towers cut one of their 10' galvanized masts down to 9 feet to make it UPS shippable. It has been up there
