Interesting that the article said 'harness's were found near the tower.' Guess that's what happens when you leave them on the ground. 73 Tom W7WHY Is this what happens when free climbing? http://www.
Hi Roger That is a very good question. I've taken a lot of first aid classes (we used to have to renew our First Aid card every 2 years), and one of the things they taught us was that if someone is i
Hi All Sometimes people put some really interesting stuff on this reflector, but it is kinda hard to read as it is all in a very long, 1 paragraph posting. With my aging eyes, sometimes it is kinda h
And making money is bad.....how??? I guess in todays envrironment, that is an evil thing. 73 Tom W7WHY The only art Bose is involved in is the art of making money. 73 Jeff kb2m ______________________
I agree with Bob. Easier to just put it up in its final place and check it. To make tuning easier, you don't have to cut the ends, Just wrap them back on the antenna until you get the right length. 7
It actually looks more like one of the early trap vertical bases. Wonder if someone tried to make a homebrew tri-bander :-) 73 Tom W7WHY Ray, I had a TH3 and it did not look like yours. I'd say its e
HI All I'm making some stubs here and they will go on the tuner. Do I make the stub for the correct length, hooked to the tuner on the output of the amp, or do I need to subtract the length from the
Yes, you have to remember - whenever you point a finger at someone, there are 3 of them ointing back at you :-) 73 Tom W7WHY Glass houses..... Stones.... I forget exactly what the saying is.... :) 73
The 'L' should work better. At 60 feet, the horizontal antenna is pretty low. I use an inverted 'L' here and am real pleased with it. 73 Tom W7WHY I am thinking of doing arrl 160 contest for the firs
Penetrox gets hard as concrete, but Noalox stays quite 'plastic' over a long period of time. I use the latter to provide sealed, conductive connection between sections of tubing in antennas. YMMV 73
Remnds me of the other day when I was at the medical center. I went to get a cup of coffee and there was a sign 'Gone on Break.' Wonder where someone who works in a coffee shop goes for break :-) 73
Hi All I've been making some more stubs, but in doing that, my MFJ-259B died. I cut one for 80, just using measurments determined by VF, etc, and came up with a stub (length (I know it's probably not
I think a tuner only fools people to think things are working right (unless you use a Matchbox type tuner and twinlead). If I have a RG-8X feeder, and I operate a 10 meter CW antenna at 28.900, the a
I assume this is a shorted quarter wave stub? Not sure what you are using to test if your analyzer died, but if it were me I would run your rig into a decent watt meter (W4, etc) and then from the wa
Can't you also hook up a filter and listen on another radio to see if it cuts down the interference? 73 Tom W7WHY Another simple test I used years ago before I had HP instrumentation was to transmit
The devil is in the details... I'd point out there are many variable so what I plan may not work with other dimensions. I think the reason they need 50' or more of coax is to tune out the loss. The l
HI All I purchased a MFJ-898C roller inductor tuner that I got for a really good price. It had a problem that it took a while to figure out. It would tune an antenna at low power fine, but at high po
Yes, it was sometines used as a feed line. As K9YC indicated there was a product sold as 75 transmission line. 73 Don K5AQ I remember good old 'twisted pair' that we used 'back in the day.' I had a H
Hi Jim I wonder if we are talking about the same 'twisted pair?' The wire I was talking about was the old telephone wire they had back in the 50's and 60's that came from the pole to the house. I thi
Surely it's not to deal with anything related to lightning, because if that were the case, then you've already failed by allowing lightning into your shack -- the place to deal with lightning energy
