72 is the QRP version of 73, because with QRP, you're making due with less.

44 is from WWFF and means the "4" directions of the compass and the second "4" means the four elements, Earth, Water, Air, and Fire.

My go to connectors for making jumper links around insulators for my segmented 40, 80, and 160 meter dipole are the blue and yellow jacket Snap bullet and sleeve quick disconnect crimp on connectors available at Home Depot. A package of 5 male/female pairs go for about three and a half bucks. Don’t understand the POTA crowd’s enthusiasm for using power pole connectors for antenna and counter poise connectors. A lot fussier to work with, and a lot more expensive than the HD snap connectors. AJ1G Stonington CT

Mike, with an EFHW, if I'm not mistaken, it's resonant on all harmonics, not just the odd harmonics - so 40m length should cover 20/15/10 as well. Plus, it might be pretty close on 6m, since the 7th harmonic of 40m would be 49MHz, and 6m is 50MHz

An 807 was a tube that worked very well for the 75 W input power for the Novice License. 807s were vaguely similar to beer bottles. Therefore a cold 807 was a cold beer. RCA power tubes all started with an "8". An Amateur for 40+ years. w0fen

The more connectors (so-239, etc) you have in your feed-line, the more loss you enter into your signal. Therefore I’d say a permanent inline choke on a run of coax is better.

LOL my cat sleeps upside down as well. I have M & P coax all ready so I just used snap apart ferrite. if making M & P coax with them nice ends they sell best PL 259 I ever had. just slide ferrite down and heat shrink. this is easy . with the snap cours just use zip ties on either end to keep them in place. I like using snap ferrite on end fed halfwave. when the coax is the counterpoise the length of coax before choke can affect tuning. just give it a try . 73's

I was working a YL one time and wanted to send "88" but felt it was a bit forward, as I really didn't know her - perhaps that British reserve. So I sent her a watered down version - I sent "44". She thought that was very amusing. It's possible that others take the same line. 73, Will - G0OPL

What is the "Center" Banana plug for on my PacTenna EFHW antenna? I'm guessing it's because all of the different versions are fabricated together, and it's for the dipole one maybe? It might be a really dumb question, but I've found that those are the best kind! On the same note, the two "GND" banana jacks on the antenna are for the counterpoise then, i'd assume... right? er no? If they are, have you ever tried connecting wires to them instead of just using coax with a choke as the counterpoise? And finally, can you tell George to have them be manufactured with the matching transformer centered in the middle of the PCB, or at least ask him why it's not located there? It would unwrap so much easier with just a thumb/finger middle toroid hole grip, provided the thing was centered. I still love it though!

For that size wire, I don't bother with links, I just have one full sized wire which does 40/20/15/10 and one which does 17. I could have another one which does 12 as well I guess but I tend not to have one of those. I don't use an EFHW for 6m as I think that's asking a bit much of a transformer built to handle 40m.

I use the 316 not necessarily for QRP, it can handle legal limit no problem. I use it more when I'm packing small and light weight. I don't use long runs of it. 50' max as it can get lossy. No more than 20' for VHF/UHF. It's really lossy at higher frequencies but for HF it works great.

As I sit here listening to you explain how to tune. I thought of a question. When you do the folding back to tune does the RF still follow the surface og the wire on insulated wire or do you need to have the loop bare wire?
@alanb76
@alanb76 Жыл бұрын
Folding insulated wire and folding bare wire back on itself so it touches is not the same. Both effectively shorten the wire, but in different amounts. If the wire is uninsulated and touching itself it is shortened by the amount folded back as though it was cut since it shorts along the length. Folding insulated wire, or folding uninsulated wire so that it doesn't touch itself reduces the length but adds end loading which effectively shortens the wire less than the physical reduction in length.
