For that kind of distance you can forget about using coax, just none available that would be worth the effort or cost. That ladder line is possible, but it has it's own particular qwerks to deal with. If possible, that remote radio would probably be your best bet. Before I did any of those...

I've had several versions of HRD, some were more stable than others. The latest version, 6.1.something or other seems to be stable, so far. I don't use it much, I have other programs for specific 'digital' modes and don't care to computer control the radio. If it works for you and you like...

Generally known as an 'Armstrong' rotor. I can remember doing that with TV antennas too. - 'Doc

Lil'Yeshua, One site that does give 'real' information about antenna systems is 'K0BG's. It isn't the only one by any means, but it does tell you how and why things happen. A lot of the information there is going to seem 'wrong' for a number of reasons, but you really can take it as 'gospel'...

True story or B.S., who cares! That has got to be a gene-pool cleaning idea. - 'Doc

If I were selling coax and my conscience wouldn't bother me, I would recommend the most expensive stuff I had. But, I would recommend using a cable with minimum losses at the frequency range you were going to use it in. For there to be a notioceable difference because of that loss, there would...

Unless a mobile antenna has a matching device, it's not going to be 50 ohms impedance, probably not even close. Part of it is in how/where the thing is mounted, yes, but there are a few other considerations that have to be taken into account. I would suggest you using an antenna analyzer to...

"If you have two 75 ohm coax run parallel shouldn't the impedance of the coax be 37.5 and then when you add the two 50 ohm antennas to it shouldn't it add up to 62.5 give or take." You're missing a component of that antenna system, you aren't including the input impedance of the antennas. So...

What it amounts to is that there's no 'magic' lengths. Use the length that will reach from here to there and then tune the antenna so that it has a good match. That's not a simple thingy, there are a lot of factors in it that you have to account for. The 'myth' that there's a 'magic' length...

Yaesu has a program that will do that programming. Not the simplest thing in the world, but it'll work. Just learn to do the programming. - 'Doc

Nope, no on-line testing. It's certainly possible for the Ve's to come to you, though. Just depends on how scheduling works out. Ask your local club/Ve's if they'll do that. Some will, some can't. - 'Doc

Never heard of them. Did you find a price? - 'Doc Oops... $1500.00 for one? I think there are certainly less expensive antennas, and I see nothing all that desirable about that one.

An interface such as those made by 'G3LIV' will certainly handle most applications. I have one his 'dual' interfaces that can handle HF/VHF and their typical modes. - 'Doc

If two radios/antennas are all that you will be using, then another switch such as you have, but in the other direction, should do you. - 'Doc

How about another antenna switch? - 'Doc

There are no 'absolutes' about brands/models/styles of antennas, they can all be very nice performers. The same antenna in a different situation can also be terrible. I found a particular spot to park at work that for a number of reasons was @#$ near perfect! Move 10 feet and things went to...

FWIW I don't know of any 'ham' radio that's built to 'commercial' operations standards, constant transmission isn't normal for ham stuff at full power. Reducing power for longer duty cycle stuff is absolutely normal and smart. You could always add extra cooling, but that's not always...

I do that "boring old men stuff" a lot. Lot's of 'skin', some funny stuff, and I love 'changing' pictures. Never send me one of yourself! Oh, you'll regret that. But that's just some of that "boring old men stuff" you know... :) - 'Doc

Was bored so set up the SSTV again. Had to experiment 'cuz I forgot about how to get things connected. Finally got it going. Only have a 40 meter antenna at the moment so not exactly the best signal on 20 meters, but, it works. Forgot how @#$ addicting this stuff is and am paying for it...

The easiest way to find that sound card software is to google 'AGW packet engine'. There are two versions, one free and one not free. Both work. As for how to specifically connect your '281, I can't tell you, but it can certainly be done. Good luck. - 'Doc
