Re: [Elecraft] OT: K3 and High Tension Wires

Please reread the first sentence of my prior post, in which I qualified what I said with the phrase “…if it’s functioning properly.” What I said is NOT in conflict with your points. Power line noise is, de facto, the result of some sort of equipment failure. We agree on that. If something is

Re: [Elecraft] OT: K3 and High Tension Wires

The Loftness book is the "go to" text on power line noise. EVERY metal-to-metal junction is suspect. Lazy linemen hammer lag bolts straight in when installing cross arm braces. Metal steeples holding ground wire running down a pole arc and set poles on fire. The list is endless. 73 K0PP

Re: [Elecraft] OT: K3 and High Tension Wires

Lew, That's in direct conflict with everything I've seen from RFI engineers. Over the years, I've seen plenty of reports of hardware in the power system failing in a mode that causes it to arc. See http://www.arrl.org/power-line-noise for a great discussion of all sorts of RF noise,

Re: [Elecraft] OT: K3 and High Tension Wires

Drawing from a decade of experience working as head of the PR department for a major electric utility (a long time ago), I’d like to suggest that arcing per se should not be a problem at any time with any power line if it is functioning properly. The individual transmission wires are spaced far

Re: [Elecraft] Portable 60-80m wire antennas

The antenna efficiency drops very quickly when the radiator is made shorter than 1/4 wavelength or 66' on 80 meters. When end fed the efficiency of a short radiator is even lower depending upon the "ground" return system. The RF power is divided between the radiator impedance and the "ground"

Others might be interested ... We moved here to Sparks NV last Aug. Prior, we lived on 5 rural ac outside of Auburn CA for 38 years. Distribution lines were 12 KV, we had our own pole pig. There was a 69 KV tie line on wood poles between two hydro plants that cut across the south corner.

G'day all, Time to put this saga to bed. Further investigation revealed that my Toshiba Netbook with a slightly earlier version of Logger32 (3.50.231) ran software CW (DTR keying) over the KIO3B USB port without issue. The main PC was running version 5.50.252. I transplanted the Tosh version

I've always been a fan of end-fed half wave wires for portable operation, as they don't require a ground system, nor do they require a balun or feedline. The inverted L configuration works well, as the high current point is a quarter wave from the fed end. Make that as high as you can. The

Hi Bruce, Have you thought about using a 9:1 unun and about 100 ft of wire with a short counterpoise? The unun -may- get the feed point Z down into the range where the KX1 tuner can match it. I picked 100 ft because it's not a quarter wave or half wave on either 80 or 60 plus and it's more

I've had good luck with antennas made from RS 22 AWG Speaker wire and an Elecraft BL-2 BALUN. A 100 ft spool will yield a 135' doublet with about 30+ feet of "twinlead" feed line. You can make insulators from pieces of plastic toothbrush handles. Add a kite wonder from BuddiPole or other QRP

[Elecraft] Portable 60-80m wire antennas

Hi folks, For 40m, 30m, and 20m, the KX1 docs recommend a ~24' length of sorta-vertical #24 wire with shorter counterpoises as a good field antenna. I've set that up for my KX1 and KX3, and (unsurprisingly) it works well on both. For 80m, the KX1 docs recommend a resonant antenna, and I'm
