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.
correct
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.

44 (Answer promptly by wire/Answer quick) means "please log QSO promptly"
A cold 807 was code for a beer. The 807 was a popular tube of this era.
Yes 807 is a Beer, I only heard that from older Hams.
Said vacuum tube was roughly beer-can shaped.
Three tantalizing questions with three tantalizing answers... Fantastic! LOL! 73!
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
great video thanks Mike!
44 is half of 88 (Love and Kisses) and essentially a "handshake" google CWops CW Abbreviations, it should pop up. Commonly used in Flora and Fauna connections, which if buds was doing POTA would be self-explanatory as parks generally have both flora and fauna!
I just ordered that choke. I used your code. Stop spending my money Mike!
44 is the equivalent to checking the Please Respond box on a QSL card. They are asking for you to formally acknowledge the QSO. (by card, or electronic)
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
Another great one Mike! Ya know I’ve always wondered the same with 44,88, etc. I just never asked.
73!😂
For field repairs, the Pinecil "smart mini portable soldering iron" is a great piece of kit. It's USB C powered, no need for an inverter.
Mike, have you done a video on crimping the wire? Thx. 73
I have also heard that "44" came from WWFF, but for a different reason, as 44 QSOs are required to activate a WWFF site (you don't have to do them all in one trip)
Ah yes, there is that too.
Cool DIY instructions. If you premade these ends, then you just add a section!
Hi Mike. I have a question about the Bullet or banana connectors that you used for linking extension sections. What size are they? The ones you use look smaller than 4 mm. Are they 2mm?
Thanks 73 and 44.
Trying to find a link to your video taht shows how to add the ferrel and crimp it. I need to do this, and I'd like to see an example. Please add it it our can.
Mike, where do I get those little ferrels that secure and crimp the loops in conductor wire?
Hi Mike.. 72 s are for qrpers... (good luck for qrp contacts...)... And for 44, it s used for flora fauna s activations i beleive... 🎉🎉
If you use a Figure 9 carabiner on the end, you can easily tie your antenna to a tree or pole, and easily elevate, and secure that leg off the ground.
807 the area code for a craft brewed beer in San Diego. Very popular on the west coast.
I thought you were here in Huntsville! Get over here you doodle!
"choking your....." wait, what?? OH, whew, end fed half wave. Ok got it!
LOL, seeing 44 is half of 88's that at onetime was hugs and kisses. So, 44 is just hugs. LOL, I have no idea Ham Advance since 1982
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!
Really, the fifth element is the important one. Lilu Dallas multipass.
I have received a “44” from many Europeans QSO’s, I ended with 73 and in return I get a 44.
44- might mean send a qso card quickly ?
Well that aint gonna happen from me lol!
Mike, how does one connect with you? I have some STL files you may like for tapped antennas. 73 K1TDG
where do you get your banana plugs at?
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
Great video. Do you like the 316 coax for QRP?
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.
When would I need solder/solder vs solder/crimp?
What size are the barrel connectors or banana plugs are you using?
So, for $60 you get a 2' cable with ferrites on it. Is that any better than a LDG 1:1 choke for $30?
Cool video. I’m looking to do the same thing with my xtenna. Currently cut for 40m want to add a link for 75m
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.
@paulsengupta971 what gauge wire is he using? Thank and 73
@@barryzoll9772 I'm not sure, but it looked to be quite thin, approximately the same as I us for portable use...20 or 22 or so.
@@paulsengupta971Looks like 26 AWG to me.
@@andrewgilbertson4226 Could be, but that would be very thin. I have some 24 which looks thinner than the stuff used here.
Great video. What gauge wire are you using. Thanks and “73”
It’s 26AWG wire from Sotabeams.
what are those blue things against the wall behind you? I figured it out.. blue mat on your bench.
and the guy is activating down by the river (like being by the lake or by the ocean) in a van 🤷♂️ like many other people do… it doesn’t say he’s living in it. obviously, you read that incorrectly.
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
That's the first thing I thought of, 1/2 of 88, hugs but no kisses.
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?
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.
have you every tried a SGC sg-307 mobile whip antenna? i was thinking about getting one
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.
It’s so minimal it doesn’t even matter on HF.
I dig 44.
44 likely means "I gotta poop so answer quickly so I can take care of that."
44 means "Good luck"
Mike, you choke 2’? My hat is off to you. I shall call you the intestine punisher. 73 de the pootersniffer 😅
Is the kitty oK?
I’m surprised you didn’t recognize 72 code?? It is a QRP closing comment!!
Doesn't 44 mean "Peach out, girl scout"!?
72 is just QRP 73.
44 is CB lingo for your "wife" or better half
I feel sorry for the young’ns that don’t know why the “van down the river” is funny…. 😂
When some say 73 to me Ill reply 57, as in ketchup, just to be a sierra alpha.
