... so what happened to the dog? - 'Doc

Patent the thing and you have some grounds to stand on if anyone 'infringes'. Otherwise, while you may have designed the thing, you have no 'rights' to it. - 'Doc

I think I would suggest you find a beat up old microphone of the 'right' time period and just remove the cord. I really doubt if that same cord is even manufactured anymore. If it's 'looks/style' you're after, as long as it has the correct number of conductors it won't matter electrically. If...

When you change the power output of that transmitter you will also have to recalibrate that SWR meter. If you don't do that re-calibrating then your SWR readings will not be accurate. This doesn't concern the question you asked but it's a pretty good idea anyway. Your 10 meter antenna with the...

"Quote:Originally Posted by jazzsinger View Post A stainless steel whip has approx .97-.98 velocity factor in air." "I am curious where you got these numbers. They seem a bit low to me. The dielectric constant of air is essentially 1.0, and there isn't enough resistance in stainless steel to...

Once upon a time, in a galaxy far away, I tried 'OS2' and a couple of other OSs other than MSDos or Windows. You don't wanna know about that, wish I didn't. I am not interested in learning a new OS, Linux, or any of the others. Linux may be very good for you but with some of the software I...

Just spent the last three days fixing an old laptop that had a hard drive die. Had to start from a bare hard drive and try replacing all the stuff that was on the dead one. Installed the operating system 4 times, Win-7, Vista, Win-7 two more times before the @#$ thing worked. You remember how...

Range is not 'set' by any means, it always varies according to propagation or band conditions. Your antenna system does have an affect on range, but it's not as much of a determinant as propagation. An antenna is tuned/adjusted so that it works well on some frequency or band of frequencies...

There is no particular antenna that's best for any particular radio. If the thing will cover the frequency range and power range of the radio it should do as good as any other antenna of the approximate same size/length. Any antenna will only work as well as it's tuned, that's the biggy. As...

And just to keep things in perspective, any antenna that normally comes with an HT is far from being a 'gain' antenna except for the advertising. A typical, less than 19" 2 meter antenna is at best a 1/4 wave, which has a negative-gain, less than '1'. Until you reach something closer to a 1/2...

I think you're probably right. Having any antenna close to things isn't very good. - 'Doc

Fat? Maybe a little chubby, but not fat... :) - 'Doc

I would suggest something rated for about twice the amount of power your radio is capable of producing. After that, it's a matter of whatever you can find or that suits you. Manual tuners take a little while to learn to use, the automatic ones take a little while for your wallet to recover...

A 'train' transformer? Don't put much faith in that. probably won't even come close to the current required. There's nothing wrong with having more current capacity than required, so think big. It's a fairly easy thingy to figure current requirements' but the results are always more than you...

Oh wouldn't it be great to have ALL the nice features of the high end of things?? Oh well, gotta pay to play! Figure out how to use what you got to get the most out of it. Ain't nothing 'free', so you gotta 'make do'... Right? - 'Doc

First, congratulations! Oh and you're gonna have so much fun! Lot'a things to try out. some you'll really get addicted to. Who'da thunk it'd ever be this much fun, right?? - 'Doc

Unless you want another radio, why not just buy the antenna? - 'Doc

That "as soon as they pass the test" used to be done by some groups. They would "issue" a temporary call, usually someone's in the group or a fictitious one, and the ones who passed usually ended up in trouble. No, it's not a good idea, think about it and you can see why. - 'Doc

The only thing I see 'new' here is that the ARRL is now competing with 'QRZ', and the other one that has a fee. The computer generated tests (practice or otherwise) have been available for some time (from the ARRL). - 'Doc

Install it the same orientation as the one on the board. If you can't use a diode of the same characteristics as the one on the board, use one that has lower values. That 'extra' diode is the same as a fuse protecting another fuse. - 'Doc
