Is there a recommended amount of tension or sag summer sag and winter shrink .How much tension should there be to keep antenna and if you are using a dipole for transmitting does the sag affect the SWR ?
Mr Carlson.. Do you ever sell your equipment? Duplicates?
Are you open to adoption?
I'm 52.. have a really odd set of skills, but health occasionally balks
LOL
eletric fence wire. here south of u tractor supply has like 1/4 mile rolls for cheap. might even be half mile rolls i forget. ive yet to find the end of my rolls lol 3 years later
Back in the days of the 50s and 60s, when I grew up, you could take electric classes in junior and high school in the San Fernando Valley California. So you get the basics of electricity and now I don't think they many shop classes. So there's not many people left that you can find that still work on older radios and equipment. I bought a Teac AG-D8900 AV Digital Home Theater Receiver at Costco over 20 years ago, and it from working. I called a guy in Modesto, California, near where I live in Merced. He said he only works on the older stuff. I replaced it with another receiver
Mr. Carlson never does anything half ass. Always gives it 110%. I hope he has kids. He is a perfect role model for any young man.
@@interesting7906 what are you saying? this channel has always had proper video AND audio, like well before it was 'a thing' on yt...
@@interesting7906he's making educational videos, entertainment is not the primary purpose. He doesn't need all the bells & whistles of fancy video editing. His audio is always clear, all his cuts are clean and appropriately timed, I'm not sure what else you expect - an animated intro with a theme song?
@@interesting7906 I find the whole LAB trip a bit self obsessed . All the piles of antiquated test equipment all neatly stacked as a back drop. The longwinded descriptions of undoing screws and painfully monotonous monologue punctuated by details previously explained over and over.
@@interesting7906 I couldn't disagree with you more. He is doing something that requires attention to detail, someone could get hurt or killed if they didn't have detailed information. As to your diagnosis, you're clearly not a qualified medical professional. His videos are some of the best on these topics.
Or young woman.
Mr. Carlson is the neighbor we all wish we had. Bucket truck, generator, complete fab shop, electronics guru...yeah...wonder if there are any homes for sale in his neighborhood.
it was like yesterday the day i watched you install the antenna.
LOL, I wasn’t going to view this video! I thought it was the original install one from, I thought, a few months ago.
Mr carlson just wanted an excuse for a big blue truck!
Yeah right?!?! Beautiful blue truck!!
My wife seen your truck and said,” I need one of those!” She would be snipping every twig she could see. 🤣🤣 Looking forward to your next videos.
...saw your truck...
My brother's wife rented one. He woke up one morning, bed empty, noises outside. The missus was up on the thing, all dressed up the part snipping the poplar trees. Farmer's wives, "can do" attitude 24/7.
My prayers have been answered. The GRRS will continue. Many thanks Mr. C
At the 1 min mark I smashed the like button when I heard the Grand Receiver series will resume!!!
Army field telephone wire works well for antennas....copper and steel in twisted pair configuration. Legendary toughness, hard to stretch, tinned and takes solder well. It's stiff of course and hard to strip the insulation off, but you can pretty much forget it once it's up. Comes in half-kilometer reels at hamfests! Thanks! 73 K4UIE
I wish you were my neighbor, because I could learn so much more from you than JUST simply by watching your CZcams videos, (as good as those are!), because I would be regularly visiting and talking with you, and wanting to help you out with your projects and videos! It would be great fun for me, being a major electronics nerd myself!
.... And he has a utility boom truck!!!
I have used steel electric fence wire for years for both transmit and receive with good results. As long as I have a good solder joint to the steel wire, it does a great job. I think my 80 meter dipole has been up for close to 20 years!
I used 308 stainless alloy for a wire antenna .its been working great and cheap to buy a spool
So glad to hear that the Grand Receiver Restoration is still on-going. Especially looking forward to the Collins R390 A.
Yes, I’m trying to remember if that was what I used at the MARS station at Ft Hood in 1968-9.
I used MacLean 430 SS Lashing Wire - 0.45in stainless steel
Wire is fully annealed and wax coated for ease of use. Put it up in 1988 , its still good, no rust no corrosion . Of course the the radio is in closet now because the invasion of panama was what I installed for. I got the wire off the linemen but you can buy it online. You would never need to do it again or even check it. I had tried several different types of wire before this and after time passed they all failed . Not this one
Did you mean 0.045"?
Good to hear you're moving ahead with the receiver restoration project and great to see a Mr C video actually shot outside and in the daylight
At 6:19 - I noticed the "zip ties" used to retain the ropes at the insulators. These are white which generally means are not UV protected. The T&B brand Ty-Wrap black zip ties are the best for this application.
Yes, U.V. resistant DOES matter. Some times even the black ones aren't sunlight resistant. I pays to get a decent brand like the kind you get at an electrician's warehouse. I have had problems with cheap wire ties right down to the mechanical lock inside.
The Thomas and Betts (T&B now ABB) brand Ty-Wrap model "zip ties" are considered best-in-class made of high strength nylon with an imbedded stainless steel locking tangs rather than the more commonly found plastic tangs.
@@cemx86. Yeah, I forgot to mention that. Surely the black ones are better than the white ones?
Right. Black UV resistant cable ties will last much longer
Agreed! I always use Ty-Wraps with the metal tongue. They are great and very long lasting no matter what the application.
Hey Paul,
Great vid! Fifty years ago, my 6th grade teacher ( Dutch W1GXY ) and I ( WN1USM ) put up my first dipole antenna ( 40 meter band ).
We used Copper Weld wire-which held up beautifully-well into my college years. We stretched it between a pine tree and a back porch post. We used rope and a clothesline pulley screwed into the tree with a plastic weight plate hanging down near the trunk. During wind storms that plate used to fly up and down as the tree swayed!
I was going to comment on the white zip ties, but I see many more have already. I used to work for a Photo Voltaic research company and we wired our array sensors with white zip ties. When we went to decommission the site, the zips just crumbled in our hands.
I love how transparent your welding wire is, my Copper Weld was plainly visible.
Nice job!
George ( WA1USM )..
I absolutely love that truck. You are too cool. Next, if you just had your own small nuclear power generation facility, water well, underground cistern system, and septic system.... Seriously though, the truck is amazing. Thanks for another thoroughly entertaining video.
Nice Cherry Picker that a real one. Always impressed by your attitude towards Electronics ... legend you have become.
Thanks again Mr. Carlson!
My wire antenna was a dipole made with Copper Weld wire, with 450 ohm feeders. It had been up for many years and finally, this year, the wire rusted out at the feed point, which is up on my tower, about 18m high. Now, I am doing a lot of thinking about my climb up to it!
Yes the GRRS will continue! :) I can't wait!
Beware white zap straps and UV. I cable tied my fluorescent lights to the rafters in my shed. One morning they were all on the floor. I then tested black and white ties from the same company, just left them out doors, the white translucent ones went brittle after a few years, the black did not. I'm guessing that the pigment in the black ones stopped the UV getting to the core. The white ones snapped like match sticks, totally cooked!
Greetings from the UK, love your videos.
I had a similar experience in an office environment with a fluorescent tube wrapped with multiple natural nylon cable ties. The UV that leaked through the phosphor embrittled those ties impressively. They crumbled like broken glass after a couple of years in place.
Mr Carlson I do enjoy these videos and have for many years now..Thank you because I know camera work and editing are way more time consuming than most people realize especially to make the quality of videos that you do..
Not to mention the editing!
Very long we have must wait, to see your antenna, now its all clear, he has an antenna^^
HOW WAS THIS PUT UP YEARS AGO?! I feel like it's been months at most! 😳🤪😅 Looking good!
Times flying!
@@MrCarlsonsLab That it is.
What a great piece of equipment to have at the ready, that bucket truck must be a dream to own. I have two 40' Rohn towers with multiple antennas, vertical's and twin stacked arrays and now find myself struggling to climb safely doing maintenance, envious for sure. Spring tension on the antenna is a great idea and yes the wire looks fine IMO. Glad to hear the restoration series is in the works, thanks as that is educational as well as enjoyable. Nice video Mr C., much appreciated. 73
Mr Carlsons lab your light blue truck with a cherry picker is awesome my friend
I am so happy to hear that you will be continuing the receiver restoration series, I have been waiting for it to continue.
If you have a friend who works on aircraft, there's some .032 safety wire that's used to safetying aircraft components. I used it for a solar dryer (clothes line), and its lasted about 30 years. There's more than one type of wire. Some don't rust, and some will look tarnished, but hold up fine. I enjoy watching your content working on the old radios. I'm not much of an electronic guy, but it's interesting to see what do. Tommy
Oops, I hit the send before I finished my reply. I wanted to say: from Costco, but I'm not that happy with it. I think my Teac overheated and took out something in the channels. The subwoffer still works.
Great video as always. When you say it takes x2 re the project and x4 when you add a camera. What would be interesting is to do a 25 minute video but show it from conception in your mind to the upload to Pateron or YT. That would give us all a real insight into how it works 👌
Doesn't every one have a bucket truck! nope! some of us Peons still have to climb manually haha. thanks for sharing ECF
This peasant is too old for ladders and exploring the roof!
Really? My comment got deleted for calling myself a peasant that's too old for ladders? Too many Karens here.
I see both your comments.
@@PlanetaryThoughts9861your posts show up fine.
The last time I did antenna work on my tower I rented a bucket truck from U-Haul and it sure made the task much easier. I will admit the controls took a little time to get used to but all in all it was well worth it.
Shortwave radio - 📻 enjoyed the video
Thanks 👍
It looks like even though we're both on the same northern latitude (I'm in Maine) , you're pretty much 3000+ miles due west of me, your trees are much further into spring than here. We had about 30 inches of snow around Easter!
I would love to see you do a video on modifying the MFJ-259B of yours. I've got the Nano VNA and I'm starting to use it. Maybe showing an alignment of an RCA AR-88, which requires more than basic alignment procedures and comparing the best verses the cheapest test equipment. And then, for good measure, show the VINTAGE way of aligning these communication receivers. I don't mean a complete alignment, just one section to show how the comparing how different equipment works. One thing I love best about your channel is the test equipment the you can build yourself. When you don't have to comply with U.L., factory, or FCC requirements, it is amazing how much simpler the test equipment can be!
I see you have a garden and greenhouse. I would love to see a tour of these. Maybe include electronic projects around these. Just some ideas I'm brain storming (brain farting) around. I love your videos! It's nice to get outside the shop with the spring fever we've been having so thanks for bringing us up in the air with you! 73 and take care!
Oh joy! An outside antenna video. I'm all in! Thanks, Paul.
Sir Mr Carlson Lab very impressed! Great athleticism the way you climbed into that cheery picker and scaled it!
He moves like a cat. lol
@@robertheintz8017 He sure does! Lol.
My wife and myself always enjoy all of your videos.
If I was a younger man, I would love to have your antenna.
Can I borrow your truck?
I do have a rope that I had put up 30 years ago and it is still up between two trees.
Thank you again for your videos!
I love your field trips !
Great news. I was wondering about the receiver series. I started with a CR-91A receiver more than 40 years ago. These old receivers are greatly under rated. Cheers!
Good idea getting up there to check on the wire. Surface rust can be chemically treated later and an anti-oxidative coating
applied then. It should last for several years. Lovely looking area of Canada there Mr. Carlson.
Mr Carlon quite rightly so, You and your family live in a stunning house and gardens (yard you guys call it- that aint no yard) ...Sir your a clever man, and do amazing things that even non engineers are drawn to , esp the 'old radio restos' ....keep it up , its well appreciated
The breaks to see the outside of the lab are a nice touch.
Zip strips, zip ties, we always called them "zickers".
Nice landscaping by the way.
Might be difference in climate - but zip - ties only seem to last about 4 years or so outside in our Texas sun and heat. They still look good, but look at them hard and they snap like glass.
The antenna system looks to be holding up well. Thanks for taking us up to look over things!
I would give you a million thumbs up if I could Paul. I absolutely love your channel!! All the best from Gene in Tennessee.
Thanks Gene!
Just a quick thought if you are looking for a stainless wire replacement. The lashing wire we use to hold up fiber and coax to the support strand.
Tested good for decades in weather, not too expensive!
Thanks for the great videos!
You can buy stainless lock wire from places like Princess auto and harbor freight it's fairly inexpensive and comes on a spool it might be a source of corrosion resistance antenna wire I believe the largest size red tailed available is .041 inches in diameter ohh it's sold as an aviation product and is available from non aviation sources for less money
Have you considered putting a common-mode choke at the feedpoint of the antenna? Without it, the outside of the coax shield effectively becomes part of the antenna. Since it enters your lab it will be prone to pick up noise there, which can then flow back up to the feedpoint and then back to the receiver. I am sure your antenna is efficient, but s/n ratio is more important in a receiving antenna.
You know, because if you i just finished fixing a tek 317, then did my first AA5 this weekend. 1958 rca circuit board! Thank you sir.
Thats great! Congratulations, and thanks for the kind feedback too.
@@MrCarlsonsLab it's well deserved! Through your patreon I've gained so much knowledge and drive to fix what's going to inevitably end up scrapped or dumped.
@@MrCarlsonsLab by the way, I need more Vedolyzer in my life!
Zip straps should be black . They are UV resistive .
Well, he needs a reason to fire up Big Blue and ride the bucket every few years!
IMHO I would agree with that. However, it may be that the tyraps will open and let you know that the wire also needs to replaced. Sort of long duration hourglass?
Fantastically engineered system, I love it. Nicely done as usual.
Ok Paul, if that is your truck, I am drooling!! 🤣 A vehicle like that makes so much of our antenna work substantially easier. Cheers and 73
For people asking about Mr Carlson putting up this ariel using the cable, method he did ...
I refer you to the '80's film '*The Thing*'
When 'MacReady' is about to take up the chopper in an oncoming snow storm, 'Bennings' or 'Norris' says
"McReady is mad taking her up in this..."
'Palmer' replies
"*He knows wat he's doin...*"
As does Mr Carlson...😉
Thanks for the update. That's a nice little truck you have there!
Just look at old mines you will see rusty steel baling wire laying in the desert that is still good and 100+ years old. Excellent job on the antenna tower.
Thanks for the 3-6-9 antenna update! Looking forward to the Signal Corps BC-348 series.
73 Paul AA1SU
Such a beautiful place.
Lovely looking home
Woohoo! The blue bucket truck is back 😀
Thanks for video. Great job.
Mr Carlson never ceases to amaze me. I have a question. Who has their own personal bucket truck?
Looking forward to the Grand Receiver series!
Awesomeness squared 😎 Mr. C!
Awesome? Did it inspire awe? I'll help you - no, it didn't.
Being an antenna guy, (get it?) I really like your over kill on that pretty blue truck, be careful or you will be fixing everyone's antenna around you! The nylon ties can go out from ultra-violet light long before the wires rust. WA7VQR
Thank You 👍
You're welcome!
GRRS will be returning, thank you Professor Carlson !!!
Thank-you for another great video Mr. Carlson. :)
My pleasure!
Love it Mr. C. In the past, I've always had someone else put up my antenna. Terribly afraid of heights. I think I would be okay in a bucket. Cool truck there.
When I became HAM in the late 1950s the preference for wire antennas was to use copper clad steel. It has excellent corrosion resistance, strength, and works best as bare wire. It is available as dead soft steel as well as medium and high strength steel cores. Insulation is subject to UV related deterioration and greatly increases wind resistance. I believe insulation also accumulates more ice in the winter. Surprisingly, copper clad steel antenna wires provide superior conductivity and less signal loss due to seemingly enhanced skin effects. I never understood this, perhaps it is related to electromagnetic properties of steel. This does not apply to DC however which can cause a satellite signal coax to fail in delivering the DC for antenna mounted electronics. Use solid copper for anything like that.
Stainless steel wire has a habit of failing under conditions of constant changes in tension. There is no warning of weakness before failure either. For this reason it is almost never used in sailboat rigging. High strength steels are hard to bend. Unless the wire is long and requires high tension to reduce sagging, mild steel is a lot easier to work with and generally adequate.
I have used electric fence wire for such an antenna. It's galvanized and doesn't rust. Very low cost. Very good spring tension device on yours.
Nice digs.
intersting things you check out, love this stuff..
Always love videos on interesting antennas! Have a video myself on my multiband dipole working so well! Also very interesting to learn about all the radio operators in Norway at the 2'nd world war being traced and killed, for whomever interested in some history lessons! Thank you so much, man, for your very good and interesting videos!! :0)
Look pretty good for how long it is outside in the weather 👍👍👍
Pleased to hear the grand receiver restoration is going to continue. You covered my favourite (CR88, I have an AR88 to restore) already, but would like to see the results of the others and their final comparison. Thank you for your efforts on these and fully understand the points you made on Patreon.
Like the bucket truck!
But this is a radio channel not a bucket truck channel.
Welding wire is pretty tough stuff, i keep the left over wire in the whip when i change out my spool and use it in place of mechanics wire
Its holding up well. Zap Straps are called "zippy ties" in Australia..
Good afternoon, i forgot you still had that bucket truck,great video,thumbs up
24 awg magnet wire setup as an end fed half wave has been amazing for me. I've gotten cq's 5/5 from over 4,500 miles away w/ a basic 100w rig.
Super cool ! 😎
That antenna system is neat. You put a lot of pride in your work and it shows. I saw one item I would change, and that would be the white ties holding the rope. Here in FL white ties become brittle, basking in the sun, so it is recommended black, as they last much longer. . Love your videos.
Great video Mr Carlson sir you are awesome engineer thanks for the sharing this video sir ❤😊😊❤😊
You are very welcome
I use electric fence wire. It holds up well.
I think it's the first time I have ever seen you outside your lab.
GREAT VIDEO !!!!!!!!!!!!!!!
Thanks!!
Rust or not, holding up just fine!
Totally agreed that restorations can be extremely time consuming. Doing a few right now... and sometimes I can't Keri on just like that, I need to take a break and do something else because things are not going as planned and I need to retrace my steps, get some parts etc. But when you get it right, it can be so satisfying.
Greetings from Reno, Nevada.
i agree with everything in this video other then the camera adds x4 the work. Im sure its more like X6 times lol
I thought that maybe you had given up on the grand receiver restoration series. glad that you will be getting back to it!
Absolutely love your video's and gives me hope for my electronics projects. One thing I would say about this video is for safety only. Having had to work in one of these bucket trucks in one of my past jobs is a requirement to wear a hard hat and also a safety harness to attach your body to the bucket. I remember hearing about a poor guy who fell out of one and died. Please be safe my friend! You are obviously an electronics genius and am in awe of your talents. Jim C. from Holyrood, Newfoundland, Canada. I'm going to subscribe to your Patreon channel. Definitely a bargain for your knowledge
A word of caution. Solid "mig" welding wire is usually coated with copper at the manufacturing facility. I'm guessing that Lincoln Electric still makes their mig wire this way. The copper coating on the steel wire serves two main purposes. In the mig welding process the system feeds the welding wire at a constant speed from the wire feeder into the mig welding gun. At the business end of the gun there is a copper tube called a contact tip. As the welding wire passes through the contact tip, that is where the wire picks up the DC welding current from the welding machine. The copper coating on the wire gives good conductivity from the tip to the wire. The copper coating on the wire also makes for less friction between the wire and the contact tip. The copper coating on the weld wire does give some resistance to the steel wire corroding but the coating is not designed to give maximum corrosion resistance to the wire. The copper is usually no more that a few thousands in thickness. Once the copper coating has fallen off the welding wire, for whatever reason, you are left with normal corrosion between the steel wire and water. I would be surprised if anybody got more than a year or two out of this antenna before it broke.
I'll let the ranchers know their steel fence is fucked. They will surely get a much needed chuckle.
Hi Paul,
I have this idea on building an AM oscillator detector that makes a zero beat tone when it gets a signal from the local oscillator. It will be calibrated to detect from 985 khz to 2155 khz. I don't have a frequency counter and that would make it easy but I like building test equipment and so far it isn't working. The idea is to build an oscillator from old AM transistor radio parts using the red coil and the output from the oscillator goes to one terminal of the primary of an audio output transformer. The other terminal goes to an oscillator of the radio being worked on and the output of the transformer goes to a speaker and when the two oscilators get close in frequency to each other then the speaker will start to make a zero beat tone but so far it isn't working. I think I need to build a differential amplifier instead of using a transformer. I like building radios from spare parts and the most challenging is getting the converter transistor to oscillate at the correct frequency. I built a modular FM radio and each circuit is built on a separate board and plugs in. The tuner/ comverter section is on one board and plugs into the first IF board then second IF, then ratio detect and finally the audio board with speaker and it works. All of the IF transformers and everything are made by the factory but what if for example I want to test a homemade IF transformer. I can do that by plugging the section that I made to see if it will work and that's why I built it like this. Now if I can get my modular AM radio to work. It works but it breaks into oscillation at a certain point on the tuning capacitor. I can't believe AM is giving me such trouble my FM modular radio worked the first time oh well 😁. The most challenging and difficult one to build was a long time ago when I worked at AT&T I had access to some really fine test equipment and I built a dual conversion weather band radio and it took quite a lot of experimenting. It was built all on one board. The front end had to use small signal FETs I couldn't get bipolars to oscillate at that high of frequency
Nice sets to think about R11555 T1154 and Set 19 .
of course you own a bucket truck. LOL love your show. MORE GIANT AUDIO AMPLIFIERS please
That's an interesting choice of wire! Personally for an EFHW, and since I only run QRP up to barefoot, I use 26ga magnet wire with a chrome-moly wrench counter weight. It lasts until a big storm then I break out $0.49 CAD more wire for a new antenna.
But what size wrench?
@@ShainAndrews 14MM of course!
Can I bum the boom truck? Gotta trim some trees.
I want to interview his neighbors...
Mr Carlson, are you a ham operator? I have always wondered that. I would really enjoy finding you on the band one day and getting you in my logbook!
Yes I am!
@@MrCarlsonsLab Oh, now I'm going to be searching the bands for your voice every day. LOL 73 de N1MJF
I remember the first antenna I built for my Heath kit. I unwound an AC blower motor and strung the copper wire on my parents fence
