Over the years I have noticed that the better conditions on 160m often occur between early November and late December. Propagation sometimes goes into the doldrums after Xmas and through the end of F
For many years I have used silver alloy brazing rods that are sold in most any welding shop. They are sold for use with copper plumbing, since local codes now prohibit lead solder because of the dang
Can anyone tell me where in the USA it is available? Mine is designed for use as overhead drop cable. I bought a large spool of it at a hamfest for $10. It has a single strand of galvanised steel em
My solution to the deer problem with my 900' beverage is #8 copperweld, overkill on the size and breaking strength of the insulators and anchors, and plenty of tension on the wire. I could probably u
From: Ralph Matheny <mathenyr@marietta.edu> As you say, the loops/flags/ are a great tool in a tight situation, as here in town with little space. Use >them all the time, even for 75 meter rag chews!

I once had a brass blade fan from1925. I didn't know it was brass. I put it in the sink and sprayed it with 409 cleaner. I thought I had ruined it. stuff was running off and lots of streaks. The 409
"I am looking for a source for ground radial wire. The THHN at Lowes is a bit more than $0.09/ft for #14. Hoping to do better than that. Saw a reel of #18 at hamfest, 2000' for $95, I guess I should
The base impedance may be high due to top loading provided by the antenna, not necessarily due to ground losses. My tower is 127' tall, insulated at the base. At the 119' level (top guying point), I
An indication of propagation on the lower frequencies these days, maybe due to the current lull in sunspots, or maybe it's my 900 ft. terminated beverage receiving antenna aimed towards Europe. Proba
<> Use strain insulators next to where the guy wires attach to the tower. If you run over a few hundred watts peak power, series two or three insulators in a chain right at the attachment points. The
In ET Docket 12-338 the FCC proposes to raise the secondary amateur service allocation in the 1900-2000 kHz band segment to primary status, providing amateur radio operators nearly exclusive use of t
Here's an example of the kind of opposition we may be up against, who may file comments in opposition to the NPRM, since Lindgren Pittman Inc. likely won't want to recall and re-program units they ha
Could you support a vertical 1/2 wave for 160 with aballoon? You could end -feed it at the base through a 1/4 wave of 450 ohm ladder line and it would be a FEARSOME 160 antenna! And the whole radial
Then, why do broadcast stations that use vertical towers at approximately a half wavelength, purchase valuable real estate and spend thousands of dollars for the copper to install from 120 to 240 or
Tom is correct in that a half wave vertical wouldn't have zero current at the base feed point; I should have said "near-zero", since if it actually had zero current there would by definition be zero
THE CLOCK IS TICKING! The FCC website lists the COMMENT DEADLINE as 25 FEB 2013, and REPLY COMMENT DEADLINE as 27 MARCH 2013. Published in Federal Register on 27 December 2012 Proceeding Number: 12-3
The deadline is the 25th of this month. Just 17 more days left. Even if you have zero interest on what goes on above 1850 kHz, it is still crucial to get this passed. In the albeit unlikely but fin
Looks like the first, and so far only, comment has come in (they missed the formal comment deadline), opposing the proposed 1900-2000 kHz changes. http://apps.fcc.gov/ecfs/comment/view?id=6017166561
A closed mouth gathers no foot. 73, Don k4kyv Jim Yuri, stop shitting on political issues amateur radio! You want to be really smart sitting in K3-land and flinging mud at all. P.S. why you all sat w
