Get Out - Portable Ham Radio!
Building a 6m Magnetic Loop Antenna in 60 Minutes
Ever wanted to build a magnetic loop antenna? Let me show you how I built my 6m magnetic loop in just 60 minutes with parts available from your local hardware store or found around the average ham shack. #hamradio #hamradioantenna #magneticloop #magloop

De-boxing Day #003 - WSPR Transmitter for comparing antennas
Переглядів 91Місяць тому
I've been told that opinions are like arseholes; everyone has them! And that's definitely the case when it comes to antennas for ham radio. So, to try and separate facts from opinions, I ordered two WSPR transmitters from ZachTec. The plan is to use these for side-by-side comparisons of a range of HF antennas, and to be able to make decisions based on empirical evidence instead of unsubstantiat...
Small, lightweight balun choke for QRP operations
Переглядів 93Місяць тому
(Excuse the mumbling in the last half of the video, I think I forgot I was talking to someone other then myself) I recently took delivery of the 6m carbon fibre mast from Sotabeams. Planning on getting together a extremely lightweight and compact kit for portable radio. Starting with a simple choke balun for QRP dipoles and verticals. Parts used in this build are: - T68-43 toroid - About 50cm o...

Is it a ham antenna or cb one
Looks like a nice start for a project 😁
That’s almost 20 kg of aluminium, so hopefully it’ll be enough for quite a few projects 😀
Just subscribed
I have to try this. \
Good luck, and let me know how it turns out!
I keep looking for you on FT8! I saw you once but couldn’t make the connection. Take care, N3OA
Looks nice!
Funny you have just published this as today I've just finished my 6m mag loop too... An offcut of elliptical waveguide rather than plumbing pipes. A coupling loop rather than the ferrite and a small butterfly rather than your co-ax inner. Just over a foot in diameter but just like you I'm very impressed with it's performance. Picking up Slovenia from inside the kitchen here in Scotland. Q is very high (showing good low losses) & certainly need to retune the capacitor depending on where in the band working. Totally agree with you that these little mag loops can be great fun to build & play around with & that they can provide amazing results in restricted circumstances.
Nice work! Sounds like a piece of kit! Looking forward to further experiments with magnetic loops in the future. If have some pictures of your build (either "in progress" of finished product) feel free to share!
Opinions are like assholes everyone has one that they cover up!
The hydration technique used was probably the most important step. 🙂
Tou finally made it a short
US2IX 👍🤝🇺🇦
Why didn’t you include video showing the DX contacts?
You're making great progress. Kudos!
Thanks! Looks more impressive then it is tho'. The "CQ" and "LB5JJ" are muscle memory by now. I couldn't send anything else nearly as smooth :-)
It does look a wee bit warmer there than Norway at this time of year.
I recently hiked mt Whitney which has a summit around 15k feet. When the snow melts I plan to go back but I’d like to make some contacts while I’m up there. What would be my best bet for gear? Some sort of dipole?
Weight is the key! You don't normally need much in the way of an antenna on a mountain top. If there's mobile phone coverage, I'd recommend spotting yourself - you'll have a pile-up in no time! Be careful and good luck with the activation!
What's the white stuff on the ground? Is that white sand? LOL! I from the Central Coast of California where it's about 60 degrees Fahrenheit or 15 to 16 degrees Celsius year round. Looks cold, fun, but cold. 73
I used a stepper motor and an Arduino for my Mag Loop years ago. I ended up giving it to another ham though. I miss it now. 🥲Great Video. Thanks for sharing! 73 de W6OBB
What a beautiful day.
awesome video!
Didn’t understand this at all but it certainly is vibey 💃🕺💃🕺💃💃💃💃🕺
Nice radio great location
This is also a way to motivate you to learn CW. Because in the end, now you have to! Owning a Bengali and not using it is probably an unforgivable sin…. 😝
Awesome!
Nice scenery!
I actually prefer the scenery a tad more green, but yeah. I think my main gripe with snow mostly has to do with the melting point of water. Imagine how nice show would have been if water froze at 25°C! '
Good work! Keep the videos coming!
Thanks; it's fun this. And I think the sound improved quite a bit from the last one. Also, recording with multiple cameras and stitching together in Premiere Pro was quite manageable, even for a noob like myself 🙂
Operation is smooth and short to allow a fine tune of the capacitor. Is there an inductor as one of the components of this tuner? 73
It's for a magnetic loop, so strictly I guess you could say the loop is the inductor. But other then that, no.
Good job Bob looks interesting
Thanks! To be honest, most of the work went into writing the Arduino-code for the ESP8266. But save for a few choice words, that would probably be quite boring to watch! Looking forward to continuing the build!
Great project, and great video! Is this for the coax that you got from me?
The plan (or maybe I should say hope) is to make it into a remotely operated tuning device for magnetic loops, but make it connect/disconnect loops so I can use it for experimentation. The first loop I'm planning is a 10m to 20m loop made from insulated 12mm copper pipe... We'll see 🙂
With that much voltage you might want something non-conductive to turn it. It might also be good to have some type of position indicator so you know approximate value between uses. It will be an interesting project. 73
The current (no phun intended) plan is to use 2GT pulleys and belt to separate the actuator from the capacitor. The actuator should also drive a threaded rod so I have some way of activate limit switches and facilitate homing.
Nice place and photos

No, nothing like that! Just wanted to show the conditions walking down the hillside in the dark :-)
@@LB5JJ I understand. I was afraid that a wolf would appear in front of you :-)
