October SSS Results

John Lonigro
 

We only had 7 participants in this month's contest.  The winner for October is Carl, WB0CFF, with 17 QSO points.  Congratulations, Carl.  You will receive your October certificate shortly.

Coming in 2nd for the month was Nick, WB5BKL, with 16 points.

For the year, Carl is still in the lead (and pulling away), with 159 total points.  In 2nd place is Glen, N4MJ, with 110 points.  In third place is Chas, W2SH, with 106 points.  It seems the big question is who will wind up in 2nd place.  There are two months to go for the 2021 SSS contest season.  With a separation of only 4 points, it is certainly too close to call.

If anyone is interested in seeing the complete scores for 2021 (up through October), please let me know and I can send them to you.  At the end of the year, they will also be available to anyone interested.

72 until November,
John, AA0VE

Re: long wire

Carl Gansen
 

End fed wires have been my "go to" antenna for years at Field Days and Boy Scout Jamboree on the air, demonstrating ham radio at schools... 

 A simple "L" section tuner and a wire to a convenient high point gets you on the air. A coil of coax (10-20 turns about 4-5 inch diameter" between the "L" section and the rig tames stray RF reasonably well, but in later years I preferred the line isolator from Radioworks.

Re: Long wire end fed

K9NUD-Steve
 

I have an end-fed cut to 40m with an added inductor with about 2M of extra whip. It detuned the other bands, requiring some tweaking. It now tunes 80, but the bandwidth is narrow (as you would expect) and the performance is so-so. My 105' random wire 9:1 is outperforming it so far. Granted, the long wire is mounted higher. 

I recommend that you try it. 70 feet is often easier to find than 105 ft.

Today is the day after the SSS.  As usual, I'm reminding everyone who participated that they need to record their scores on qrpcontest.com, preferably today, tomorrow morning at the latest. I will tally the results tomorrow night and report them on Wednesday morning.

Re: Long wire end fed

Jeff, K9JP <dek9jp@...>
 

How about adding a homemade coil inductor in your end fed long wire? 
Use a piece of large gray electrical PVC tubing (UV protected for outdoor use) as the form for the coil.
Not any different than the coils used by Alpha Delta, Par Antennas, and others.

Re: long wire

K9NUD-Steve

Mike, there’s a lot of confusion about long wire antennas. Many consider an end-fed half wave (typically using a 49:1 or 64:1 transformer) to be a long wire. That’s technically not true. A long wire is deliberately non-resonant, since resonance on any band would result in an unacceptable high impedance. That’s where the EFHW works best, as the transformer can deliver something closer to 50 ohms to the radio.

A true long wire is typically used with a 9:1 un-un transformer. If the length of the wire is not resonant, the resistance will be closer to 500 ohms. A 9:1 transformer can get that much closer to 50 ohms on several frequencies, leaving a value that your internal tuner has a better chance to match.

9:1 end-fed long wire antennas must be designed to be non-resonant on all the bands you hope to use. The math isn’t too tough, and thankfully others have done it. There are several websites that mention the “magic lengths”, but most arrive at the same conclusion:  “The magic lengths to use with the End Fed longwire is 29, 35.5, 41, 58, 71 and 84 feet”

There are longer lengths as well. I just installed a 105’ inverted L with a 9:1 un-un. It seems to outperform my 6BTV and my EFHW, though the latter is not mounted as high. I’m currently experimenting with the transformer, comparing one with an iron core toroid versus a ferrite core. The ferrite is getting most of the desired bands closer to resonance. It definitely tunes easier, particularly on the low bands. I need to do more testing, and possibly add 19’ to the antenna to get to 124, another oft-mentioned length. 

I have used a 29’ vertical for portable ops with a 9:1 un-un mounted to the winder, along with a 16’ counterpoise. It performs quite nicely on 40M up. I run QRP and routinely work the whole country and plenty of Europeans on 20M. I’m eager to try is on higher bands as conditions improve. I’m also planning to add 25’ and run it as an inverted vee to see if I can use it on 80M.

I would encourage you to go down the 9:1 rabbit hole with gusto. You should also go down the EFHW rabbit hole too. Do yourself a favor and order a bunch of toroids such as the T130-2 for the 9:1 (http://www.earchi.org/92011endfedfiles/Endfed6_40.pdf) and a bunch of FT140-43’s, FT240-43’s for EFHW transformers. You might want to get some FT240-31 toroids too (useful for 1:1 current values). Have fun!

Bert N0YJ and I were discussing 
the possibility of alternate NCS.

If we have a few NCS operators 
In different locations we could reach more club members.

I’m open to suggestions.

Re: long wire

Gwen Patton
 

I had an Offset Leg Dipole for years, until it came down in a storm. The storm also took down a tree I was using as a support at the far end of the short leg, so I needed a new solution. The only other tree in the front would require me to cross over my house power access line with the wire, and I didn't like that option.

After much research, I tried a variation of the W3EDP end-fed wire antenna. I've tried it in inverted-L configuration and straight configuration. I have one in straight configuration now, and it works very well. It's not hard to make, and if you can make the requisite 4:1 current balun, it's not expensive, either. It can be made in several overall sizes, with commensurate reduction in efficiency, but it's still quite suitable. I've always been able to tune it on any band with the tuner in my KXPA100 amp or my KX3.

Here are links to all three articles:

My other base antenna is a compromise vertical, the Comet CHA-250b. It works quite well for a transformer "resonant" vertical. I don't need to use an external tuner on any band it claims to support. But as a compromise antenna, it's decent but not fantastic on any band. It does what I want, so it's ok. But I surely love the W3EDP variants I've been using. When the storm took my dipole down, I ran a half-sized one to that other tree out front, and it worked well enough to operate through winter.
