This is the first outing and the first time using this radio to make a QSO. Its a bit slow but finally getting the job done on a morning with poor conditions. The coil is the 40m coil add on for the AX1 from Elecraft. More to come but wanted to get this out there for those waiting for theirs. I did make a few contacts on 20m but cut that out of the video.

KX1 AX1 40m CW POTA Activation at Fort Yargo State Park GA
มุมมอง 72411 หลายเดือนก่อน
A fun radio outing with the Elecraft KX1 and the AX1 antenna. What a blast! I had planned to run 80m with the KX1 but somehow forgot the arborist throw line...Plan B was the AX1 on 40m. And it was killer! For my Ground/Counterpoise I sanded one of the thumb screws on the bottom side to ensure conductivity. After 11 QSOs on 40m, I switched to the MPAS 2.0 with the Mil Whip and EXT and ran 30m fo...
IC705 POTA SSB CW FT8 FT8 Buck Pocket Alabama

I had an opportunity to activate while in Alabama. All contacts on 20m with a Tufteln EFHW. I made several SSB contacts on 5w by starting with hunting POTA activators. I bumped up to 10w as things were a bit slow. I call CQ for a bit and then hunted some CW activators. I totally forgot I was in AL NOT GA! Oh boy, the patients of other CW operators! I then worked some Digital with SDR-Control on...
POTA Activation - Wilson Shoals WMA K-3777

POTA Activation - Wilson Shoals WMA K-3777
This is no good 9:1 transformer The reactance of this transformer's primary is only 17.4 Ω at 7 MHz. You need to use a ferrite here, even though you call this T80-2 iron powder a ferrite..A FT82-61 would do the job.
I bought that magnetic cover after Thomas showed it on his blog. It's excellent, provides just the right amount of protection for my KX2 in its Elecraft bag.
Is there enough room in there for your right angle adapter (the one that you make)? Thanks, Joshua
For a radio that is too damn expensive, you would think that quality control would be of a higher quality.
Joshua, Do you use a counterpoise with this EFHW? Bob AC9MG
I thought you were going to include a link to that CW key, Also, you really should do a video on how to set up that RaspPi compute module. It really does now look like a turn key type of system.
Dude, you really didn't go into detail on what you are doing with this kit.
Good instructive video. Thanks, might substitute the words diagonal cutters for "strippers".
This is great, thank you! Can you tell me how you put together your small banana clip + thumb screw for the counterpoise? I want to do something similar -- great idea.
Herr Tüftler, you know, you can write on heat shrink tubing. Use a contrasting color. I've used both Sharpy and ball point pen. Make it big, it will shrink. Might be a thing to brand the heat shrink in your kits and / or say what it is. Like 49:1 EFHW for this one. Loved the video. Nice level of detail.
Super clever idea with the heat gun! Nice work!
Very good video, keep going:)
Super!
Nice innards views. And, yeah, I agree: some sort of extra battery protection with the K tape seems necessary. Amazing amount of stuff crammed in that box. Definitely a temptation. Thankee fir the run thru. 73 de W8IJN
Thanks a really well made antenna with good methods all the way. vk5cz ..
Nice video! Just curious as to how easy/difficult are the arborist throw lines to keep from getting stuck and having to break/cut the line to try to save them. Is there something in their design that makes them better/easier to not get snagged??
Hi Joshua , would it be possible to loan me one of these , I would be keen to review it for you at my local club here in Glasgow?
Wasn't it easier to just put kapton tape on the battery ?
Like those rigs don't see them on second hand market around here in vk.
do you have an ETA on when the Battery Charger 12V Lipo USB-C will be available on your website? would love to buy that along with the battery pack.
You got it! Just posted more stock.
Thanks. They need to make some sort of cage for that to protect the knobs.
It's always nice to find someone more organized, displaying more attention to detail, than I ever have or ever will. Thank you.
Great idea with the heat gun!
Is there ESD risk with the tape???
ESD is a concern anytime you are working with electronics. Precaution should be taken no doubt. Thanks for checking out the video.
Ha! That was my first thought. We used a lot of Kapton in the lab and we always passed the strips through an air ionizer before applying.
Thanks for this video. Great to see how the pieces assemble. 73, N3CI
Too much expensive for what's inside, too too espensive !
I can’t say it’s cheap. I also can’t say it’s over priced. And obviously it’s worth every penny for me. No way will I be parting with this one! Thanks for watching.
Calling it too expensive doesn't make you a connoisseur, it just makes your wallet seem more philosophical than practical.
@@jeffdhartmanAs a survivor of the 60s, my wallet - and sense of financial security - has never been either practical or philosophical. Most of the time I am simply in awe that I still have most of my teeth (motorcycle gang ‘picnics’), am nominally compos mentis (Owsley’s lab), breathing unassisted & not dead. Which explains why I have something like five QRP POTA/SOTA rigs of various manufacture & complexity. And that makes the KH1 tempting. If it came with paisley decorations & recommendations from Wonder Warthog & Inspector Lee . . .
Won't the tape cause an overheating issue? No air can circulate around the components,
I can’t comment with any authority on behalf of Elecraft but with the tight tolerances in the rig and more specifically the flat area I covered, I seriously doubt air cooling internally on the direct surface of the board is needed. The PA actually sits on the backside of the front face at the top and used the top housing as a heat sync. Very cool design all around. Another fantastic rig! Thanks for checking out the video.
Very nice! Have you ever seen the radioset-go for the kx2? If you managed to build a kit for that it would be success. I think every kx2 owner wants that once they know it, but the price is insane. If you put together a 3D printed version, without the case and the lights it would be awesome! 73!
Great video, I used a 51ft radiator and 12 ft counterpoise. My kx3 tuner liked tuning those lengths best after several other wire configs. Regards vk5cz .
Thanks for the info!
I think the 3.5mm jack is intentionally angled so that the key "wedges" itself in place to make a tighter fit.
Yes! Such an interesting design aspect. Thanks for checking out the video Allen.
@@N5FY I'm sure their PCB design rule checker balked at that ;-)
Links?
Hey Joshua, what is or does Tufteln mean? 73 de KO4AYC
The word Tufteln is german for tinker, which is my favorite pass time, building things...and the last few years those things have mostly been radio related!
What disply? Phone?
I prefer to use my Ipad mini but can use my phone as well to access the CM4 for all digital work.
@@N5FY interesting! Maybe you could do a video on your RPI setup and your display setup, would be interesting! Thanks!
That's a sweet kit! The RPI is a nice addition. You're inspiring me to build a similar kit for my tx-500. I've thought about using a RPI for automated CW sending (contest style). Thanks for sharing. 73 de N4AAJ
Oooo mr ape would be losing his mind at a #2 toroid for a 9 to 1 uñun nice build tho Joshua' looks awesome I love the single wire wrap ill never do 3 separate wires again its so much nicer
tks for this - ordered 10/20, still waiting... which apparently is a good thing due to parts availability
Very nice cast but I think having a shorter 40M wire by adding onto the 20M wire. That would give you more room. Once I get better at CW I plan on getting one.
That’s a great idea! Just need to be sure I label or color code so I know what it what!
It was nice to see the inside of the KH1. Thank you.
I was tempted to disassemble the top as well but haven’t done so yet. Maybe soon! Thanks for checking out the video.
I did exactly the same thing to mine as soon as I got it!
tnx nice to see how my KH1 looks inside
Great video. I like your style!
This looks like fun! I think I need one, but no use here on 40m, way too few local CW ops, maybe 20m or 15m, wish it could do 10m, great QRP band. Thanks, enjoyed that, 73 Rudi de ZS2M/ZS6DX
What's the gauge of the babana connectors? Maybe 2 millimeters? Take care
Yes, those are 2mm indeed.
What soldering iron are you using?
That is a Pinecil. I really like the small iron!
@@N5FY Thanks. Do you have a make model? Or is there a better pencil iron you would prefer? Trying to find one on Amazon.
Here is the one I bought. www.amazon.com/PINECIL-Smart-Mini-Portable-Soldering/dp/B096X6SG13
Too cool for words. Thank you for sharing.
Need one for left hander
You are in luck! The logging tray can very quickly be switched to the other side! Joshua N5FY
You should turn off auto focus
Thanks for the tip! New Camera, still trying to figure it out! Joshua N5FY
Thanks for doing this build video, Joshua. Very helpful to see your technique. What power supply are you using for the Pinecil? Do you have a battery you like to use with it for when you travel? Thanks!
I am running it from my 100Ah homebuilt power bank that stays topped off with solar. I run a boost converter to 22v and feed the pinecil which will then pull up to 70w. Works very well for me. For portable I run two of my 12v LiPo batteries in series for 24v. If needed the pinecil will do most solder jobs at 12v as well! Joshua N5FY
Thanks! I just ordered a Pinecil so I appreciate you sharing that info. How do you monitor the voltage on the LiPOs in series? Sorry these aren’t antenna kit questions… I love your design choices on them though!
I don’t monitor. I use packs that have the same cells and configuration. Then check them against each other when voltage is getting to about 20%. They just don’t drift far from each other.
Super portable and great kit - built mine and works well with my T1 tuner!
Awesome video...thanks for sharing. I just received my 40M EFHW antenna kit the other day from you. So the timing was perfect! Cheers and 73, KL7CA
Great stuff! Thank you. DE W4EMB
