Hi Everybody, hope all is well. Once upon a time, before the realization that ham radio was achievable, there were pursuits to communicate 30+ miles by radio. Okay, let me switch to real time here. When Fern and I moved to Oklahoma, we worked about 25 miles from our home. I put a CB radio in each vehicle, and one in the house. Well, I like CB radio, but being the nature of what it is, and living in hill country, CB just would not do the job.
Then I discovered another citizens band radio called MURS, which is around 151 MHz, and by the way CB is around 27 MHz. But, back to MURS. We picked up a few handheld commercial radios, which are programmable, and I put the MURS frequencies in the handhelds. Got a couple of mag mount ham radio antennas, which are built to function between 144 - 148 MHz. I thought, well 148, that's pretty close to 151, and this little set up worked pretty good. We also use these same handhelds to communicate around the farm here.
But, getting back to the theme of tonight's post, I decided to go big time. Now, remember, at this time I did not have a ham radio license, and the stuff I'm doing here really had nothing to do with ham radio. So, I devised a little system. I engineered a way to raise and lower an antenna pole, which I'm still using today, by the way. I still think that it was one of my more creative moments. But, on top of this raising and lowering marvel, I put a 16 foot Comet antenna. Except this antenna was not made for ham radio, it was made for 151 MHz, the commercial frequencies, and it worked great for the MURS frequencies. So now Fern and I can communicate from home to work, depending on whether or not the car was in a low spot or a high spot, it worked quite well. But, as fate would have it, our little newspaper had a little, bitty, teeny article about a ham radio class starting. And the rest is history, especially when I found out that you don't have to learn Morse code at any level of ham radio any longer.
So I tried this radio, I tried the Alinco mobile VHF/UHF, and it worked more than adequate. Good radio. But it's a ham radio. What I wanted was a commercial radio, which is 100% legal on the ham frequencies. Now that I am spending more and more time on the ham frequencies, I needed a different antenna. Well, once I discovered the ham world, I put a couple of different antennas on the vehicles, and they work great. Then I decided I would take that same antenna, which is a CA 2x4 SR, CA means Comet. I connected it to a TRAM 1460 ground plane kit.
Fern and I took the time to put it up on the pole today, and it doesn't quite work as well as it does on the vehicles. I have two friends that
great, but okay. Well, here a few days ago I bought a new SWR power meter and mounted it permanently connected to my HF and VHF/UHF radios. It shows my SWR on the VHF to be unacceptable, not horrible, unacceptable, but still usable. And I can't figure out what the problem is. I have three different SWR meters, these things kind of grow on you after a while, then you forget you have one and buy another one. Here's the problem. My two portable SWR meters read high, but acceptable. My higher dollar SWR meter reads unacceptable, but still doable. Not the results that I wanted. So is my brand new higher dollar meter just a cute piece of junk? I wish I could tell you.
For you ham folks, my antenna analyzer shows high but acceptable SWR and the antenna tunes perfect at 161 MHz, you know, up by the railroad frequencies. But it shows about a 2 or a 3 from 144 - 156 MHz. I guess I need to reconsider my new high dollar meter, don't I? But it's up and it's in the air, and it's the first time I've done anything really strenuous since my back surgery. And at this time, I'm still walking.
We started about 2:00 in the afternoon, I guess, and finished at about 6:00pm. Fern took a bunch of pictures. And you might ask yourself, why did it take so long? Well, I had to cut the coax, solder the connectors, doctor the burn from the soldering iron, it never fails me that I will touch that hot tip.
I had to get out my fingernail polish that I use in place of lock tight.
I put Stuff on the new connections. Stuff, let's see, it helps keep out moisture, that's the main reason I use it on the connectors. And I used a new type stretchy tape to help seal the outside connectors.

But what took so long was getting the old antenna off of the pole. And it's cold, my fingers didn't want to work at 45 degrees with a cold northwest wind. I know that's not cold to some of you fellas, but I'm sensitive. I had to move my cell phone booster antenna, and I also removed an 80 meter dipole that I had constructed. I really wish that they would not use metric on these antennas, but that's another story.

Fern took some pictures along the way. I hope you enjoy them, because here one of these days, if this experiment works okay, I'm going to put up a couple of new towers and try to improve my communication system. The new antenna works fine. I called a buddy down the road to see if we could still contact each other on simplex. You see, he lives closer to the highway than I do, and when the buses come to relocate us they will stop at his house first, and I want to know when the buses are coming. You should, too. Because the buses are going to come someday. Don't get on the bus.
We'll talk more later. 73, Frank
