G'day! My goal is to educate, inspire, promote and get people involved to learn about Ham Radio!
My name is Hayden and my amateur radio callsign is VK7HH. I live in a city called Hobart in the state of Tasmania, Australia. I also hold a US Technician license with the callsign KD9SSB. I post new regular videos so go ahead and subscribe to be notified when these come out.
The content on this channel will hopefully lead you to delve into and learn more about the ham radio hobby, electronics, experimentation and everything in between. Ham Radio is a fun hobby for all ages and genders.
I've been fascinated with radio and how it all works since a very young age, in fact I first obtained my license at age 14! I hope that the videos you find on this channel inspire you to have a go at something new!

This is common ICOM May fix for Free my 705 / 7610 is great they use different screens .Cheers
Stamps and ham radio..two hobbies that turn a LOT of people away and it’s so sad
Like Jason said, "Anything is good as long as you put an antenna in the air. Put an antenna in the air, whatever you have space for and make some contacts".
Will it transmit in the 220MHz ham band?
The impact on emergency preparation will be huge long term. The absence of the antennas and amplifiers options is huge. There is not a good alternate option for big antennas and amplifiers. I think the agencies like FEMA and others should step up and help solve the issue.
It is called Moonbounce, Ham radio operators have been doing it forever

Black "Nitto" Tape, been using it since the '70's... 😂👍
Great video of correctly wrapping coax to waterproof. Used this for all my station as well as repeaters. I go a little extra and last wrap or two in Malfoy or Denso grease tape. Inspected after many years and as if new. Thanks and keep up the informative videos.
I upgraded from a 7300 to a 7610 almost three years ago and love it. Super Radio for contesting, DX'ing and plain old ragchewing.
Surprisingly simple build, and those transmissions came in pretty clean, too. Very impressive.
is the key port for the ptt signal?
very good. this is how I learned years ago. now a new product from M & P called silicone seal replaces the electrical tape and can be used but it self. just place over coax and connector and putt the string out and it and it shrinks with out heat you can use glue line heat shrink but the heat needed may damage coax and or connector. hear in NY,USA we use 3 or 4 layers on out systems. lots of snow and ice with wind.
Yes good video. The idea of stretching the tape - any tape is so that it spends the rest of it's life trying to contract upon itself. It is always tightening. I used to be an electric linesman - for the County, Borough and Power Board. On power lines/cables we would rough sand the ends so that there was a rough surface to meld to. 3 layers of PVC un-stretched to provide insinuative layer. 3 layers of tight the a couple of stretched. Of course all were over lapping. We would often leave then tapes in the warm sun and the self amalgamating we would use the warmth of our hands to make the tape become 'one tube'. After each 'run' we would extend past the last run and sometimes we had quite a long join. And yes. In the ground or in the air Denso and that too was hand smoothed. I have seen one denso join painted over and was immaculate under that first wrap. Today I don't get quite so carried away but I still use one stretched layer of PVC first. This is so that when I want to reuse the connectors they are not contaminated with sticky stuff. I am amused when I see blokes break a piece of tape off the roll and pre-stretch it, because to man handle the roll around the join and keeping tension on it is hard . We used 3m and the self amalgamating tape was thicker than the stuff in the video. Cheers Dave Creek ZL3DRC

Well, as a newly licensed HAM, I've gotten it programmed and set up in my Jeep and I hear nothing but static. I am discouraged and cannot figure out what I need to do next. I wish there were instructions that didn't use a lot of acronyms and short cut words.l for newbies. Thanks for the video it was informative, btw! KC3YCO in Maryland
Do you have it programmed to listen to your local repeaters? Repeaterbook is handy to look this info up - www.repeaterbook.com/index.php/en-us/
We finished off the the self fusing tape with Scotch Brand 33 electrical tape followed by several coats of Scotch Coat sealant. Very resistant to the elements. The Scotch Coat might need a booster coat every five years but it’s go PM to check feedlines for any abrasions that might compromise the coax.
It's amazing too when you tie a cable to a tower leg how it moves over time and rubs away the tape!
I use electrical tape to wrap around the connector and the cable immediately adjacent to the connector. Then I overwrap that with the self-fusing wrap. This allows me to unwrap and open the connector if needed, and not needing to dig all the self-fusing out of it. For the overwrap, make certain to wrap a complete turn around itself at each end, without stretching the tape at all. That will usually stay in place, but the locking tie strap is good insurance.
Super 88, curtesy wrap, then butyl tape, to seal it, then 5 layers of super 88 stretched tight to help compress the butyl. Start at the bottom and finish with an up wrap. At the end, flip the tape over for sticky side out, go around a couple times then flip the tape back again go around and cut it off. Don’t tear. For some odd reason, some people have problems using the self vulcanizing tape. We used it in the Navy in the 80s, but added Scotch Kote after.
I use quality scotch super 33+ electrical tape and I've never seen water intrusion in my connectors.
They gave thought to the first 5% of dismantling it?
Shows how a little knowledge without experience can cause misinterpretation!🤔
Everyone talks about how Low - Loss that Coax is, but if you look it up, it's not that great ? I do like the looks of the connectors, but as to such great Low - Loss, what am I missing ? 🤔.....?
Low loss vs flexibility. LMR240 and 400 have lower loss, but are rigid centre conductors
Dunno what charts you're looking at but the ones I'm seeing, its closer to half the loss of "regular" coax. And I'm not interested in LL400 or whatever because it's solid core and copper plated steel at that .
@@oldfartonabmx2122 " Regular Coax " ? 🤔.....? Perhaps you need to really study, instead of memorizing the answers ! With your comment, you have made a huge leap, mixing Apples & Oranges ! Very dependent on what you wish to accomplish ! And believe it or not, a solid conductor is really what you want ! Just because it doesn't fit your plan, doesn't mean it's wrong ! Try not to paint with such a large brush ! You may end up covered in paint ! But thanks anyway ! 👍😉
@@sleeve8651 size for size champ. you're welcome.
Just like applying a snake bite bandage!
Thanks for the review and taking one for the team. I like the screen; wishing it had an even larger one. But I'm going to pass. The screw-on battery is absolutely a complete deal breaker all by itself. I'm going to check the UV-21 and see what it's battery installation is like and that, combined with the open programming, is much more interesting to me. After a career in the two-way radio business, before my career in IT, I can see scenarios where business frequencies might still come in handy, or for after it all collapses. After a career and after 50 years licensed as an amateur operator, and just being a law-abiding American patriot, I'm won't push the button without a license but having it on the shelf for societal collapse use is a good plan.
Wrapping the connector in Teflon pipe tape fist, then overwraping with self amalgamating tape, will make it much easier to get the stuff off in the future. I have used this method for 20 odd years and it works well!
is this VHF and UHF compatible or GMRS
HRO sells similar stuff right at the counter, i used it 3 times yesterday for sealing some lines of LMR400 i ran to my 2 meter antennas. Great stuff, comscope makes a kit that comes with both butyl tape and black tape.
Dead? The bands seemed active where im at on 20 thru 6 meters.
For the VK's, Nitto self amalgamating tape is available at Bunnings. The 3M version is available from industrial electrical suppliers like Rexel.
I also make sure the last layer is layerd like house tiles overlapping when the cable is running vertically, so the lap above is always on top to help reduce water penetration as well.
is it possible to bounce signals on earth from space?, also i have in mind that uhf goes through matter, wasnt it supposed to go through the moon?
A trick I have used is if you have forced air heating/cooling running the cables through the ductwork.
A layer of electrical tape first makes it easier to remove the self amalgamating tape later, and an outer layer of electrical tape protects the rubber tape from UV damage. Don't buy cheap electrical tape, it always falls off. Get the good stuff. I use Scotch Super 33+.
Thank you very much good video 👍I am studying for my foundation license at the moment and excited to go back on air after 20 years cheers Pete
Awesome! Hope to hear you on the air soon 🎙️👍
Start on the middle and stop on the middle. Its what a mine layer said to me.
We use this at work. I did my television antenna connections with this 17 years ago. Still no problems.
Good to show people. I still finish mine off after that with Denzo tape. messy as hell but never had a failure of a plug/socket connection to the antenna even with plenty of salt water. the antenna and foundations give out first ;-)
