Ham Radio Q & A Episode 2: What type of feed line should I buy for my antenna system. https://youtu.be/FOtbpdh0D-E

Are you talking SWR - a CB radio term, or are you talking "VSWR" a ham radio term?
We always concern ourselves with SWR.
SWR means that the antenna ( Load) is not resonant.
First we work on the SWR by adjusting the length or design of our antenna.  Then we check our antenna with a analyzer.  Then we connect our feed line to our antenna.
Ladder line can overcome long lengths of feed line.   But when we design our system, we always want to build our antenna as close to the Generator as possible to eliminate as much loss as possible.
The only advantage to using ladder line is that it has less loss than coax.
The downside is that computers and consumer electronics do not like all that RF floating around.  You may gain a little on your antenna as far as being able to transmit with a little more power.  But you will not be very popular with your family or your neighbors.
This is the reason why so many people went to coax after world war 2.
There was thousands of miles of cheap, surplus coax available and it was discovered that it was a lot more tolerant to weather.

New on my blog, and just in time for Field Day, How to coil cables using the Over-Under method. If you've ever had to deal with snarled cables, coiling them this way will save you a ton of grief.

How’d you like to deploy 50 feet of coax with just a flick of the wrist. Watch the video below and I’ll show you how. Has this ever happened to you? You grab a cable, be it an extension cord or piece of coax and start to unwind it. Suddenly you have a snarled mess…

Dont forget about semi air dielectric cables too. You can damage the cable by coiling it against its natural coil and also maxing its bending radius. The center conductor will move out of center and cause an impedance mismatch or bump.

In a Report and Order released on May 21, 2015, the Federal Communications Commission (FCC) announced the elimination of the regulatory fees for the amateur radio vanity call sign program and the GMRS licenses. Their reasoning: economics. From the FCC FY 2015 Report and Order In the 2014 Fiscal Year Report and Order, the FCC…

$85 for 5 years is a bit steep for a GMRS license.
But it does give you what other radio services does not - for a fee.
Basically a quiet place to talk, where you don't have to put up with the CB radio crowd.
Amateur Radio is less regulated than GMRS - you can work it as a hobby, you can call CQ, you don't have to pay for a renewal, but then again - you do have to pass an exam and you do have to pay at most VEC's to take the exam, pass or fail!

The FCC has commented that they would like to do away with the amateur radio license all together.  The only reason why they have not is because the rest of the world will not allow it.   The USA belongs to the ITU and the ITU, not the ARRL, makes the rules.
The ARRL just makes the rules for the people within their district.

A local ham here, that claims to have been licensed for more than 50 years, claims that they should do away with the incentive license and just have one exam and give away the licenses and then he would have people that he could play HF with!
It kills the guy that half of his club only has a technician class license and they can't play HF together, except 10 meters...

I’ve been a severe weather spotter for close to fifteen years. I’ve had my share of close calls, and even more so, I’ve experienced plenty of boredom. Being out in the field often is long stretches of nothing peppered with bits of extreme excitement. But for the last few years, my storm spotter experience has…

The last image I received before the ISS went QRT on their SSTV weekend. The space station was moving away from me at this point, so you could tell the signal was getting weaker and weaker as the ISS started to slip below the horizon.

If it wasn't for Radio Shack, I wouldn't be a ham radio operator. Read more on my blog. . .

Who likes to provide communications assistance at local events? It's a popular activity of mine and you'll find me on the front lines doing health and welfare comms at a variety of events. My latest blog post talks more about the subject and includes a great video from the latest event I was involved in.

“Will work for T-shirts” That’s a popular saying by hams that like to get involved with volunteer activities. I can’t recall how many shirts I’ve collected over the years from the various walks, runs, bike ride, ski events, and marathons I’ve been a part of. Suffice to say, I can’t remember the last time I’ve…

I think the idiot you are talking about on 10, and I might be wrong, is Todd Burnett and his wife Chandra.  Todd sets up on the calling frequency 28.400 and his wife sets up on 28.425 - alternate calling - emergency frequency.  They use voice guides - a form of recorder that is used in contests to either call cq without using your own voice each time, and a way to answer people without using your own voice each time.

They basically turn it on and leave it run for an hour or two, just to reserve the frequency in case they might want to use it later in the contest.
I was told that Todd was made an O&O and that he had his job taken away from him for overstepping the boundaries set by the ARRL and so he decided that if he couldn't be a good ham that he was going to be a Legal LID.  He studied the rules, figured out what was Legal, then set up his station so he could intentionally interfere with legal communications and contests.   Todd was a member of 10 - 10 and even had awards.

New on the blog this week: How Repeaters Work. It's an inside look of a large amateur radio repeater system with explanation on how the critical components function.

What’s the most popular band and operation mode in amateur radio? If you guessed 2 meter VHF FM, you would be correct. As new hams, our first radio is usually a small handheld model. This is a great way to get started in ham radio and connect with other local hams. But your handheld radio…

I presume, +Peter Barrett and +Michael Martens you don't own a HF radio? Because if you did, you wouldn't be making such claims.

I have always wished I came up with that sign! I too am a proud UW graduate (twice over), former 4-H member (and summer agent), WPR & WPT fan, and I enjoy our beautiful public lands. The progressive stance our forefathers took with the Wisconsin Idea paved the way to Wisconsin being recognized for outstanding education; Gaylord Nelson's vision helped us to see the importance of our natural resources. Wisconsin residents have enjoyed the fruits of their labor for many years. Walker's proposed budget will strip away the foundation of their work.

Located on the edge of Wausau on Hwy 52, Lucky's Eastside Pub is worth the drive. Had lunch there on a Thursday, and even with the brisk lunch crowd that came through- our meals were delivered promptly. The sign says 'Tasty, Tasty, Tasty' and they mean it. Delicious and reasonably priced pub fare: burgers, sandwiches, etc.
