Has anyone used the db9 port on the back of the tic ring rotator controller to slave two tic ring rotators? I have one up and a second would be far less money than converting the tower to become a ro
The reason Tulip Poplars are prone to lightening is because they are generally the highest thing around. The one next to my barn/shack is now 110 feet tall and dwarfs my 80 foot towers. It does a nic
I use my first coax switch (Alpha-Delta four position) to select the radio and subsequent switches to select antennas. Think of the switch backwards; four inputs-one output. That way any of four radi
Also known as duct seal, or as some of us call it "donkey dick". Lowes/home depot sells it as does any electrical supply house. By putting mostly fiberglass insulation or steel wool in the pipe, you
K8RD said in part: When the rain starts freezing I do occasionally think of what I might possibly do to prevent it, or get rid of it. But the straight answer is, nornmally we do nothing. You did not
Jim: tells me probably your pulse leads are not delivering the pulses from the rotator to the controller box, or the MOV took a hit. check all connections between pins 5/6 and the rotator unit. There
If you are voltage feeding length is not critical. 468/f for top and 234/f for ends should be sufficient. You can tune it with the variable C. If you are current feeding it, then a bit more critical,
Dave: I have a 40 meter delta constructed for field day. Our field day site is on the bank of a salt water river, and I suspend the base of the delta over the water. Works very well indeed. I support
Dick: Yes, a 2 by 2 piece of Oak 8 to 10 feet long, heavily varnished and guyed with non conductive rope or Phyllistran. Keeps things non conductive and wires and feedpoints away from the tower. 73 b

Concrete reaches maximum strength after a cure of about 30 days. No way I would do anything for at least two weeks, and if the tower is loaded I would wait the thirty days. Not a safety issue but a l
Mike said: If your tower base needs cooling pipes, your antenna is too big NO MIke, you can never have too big an antenna (or too many of them). The wallet and volume of its contents is the primary l

I am not a modeler, and honestly have no desire to go thru the learning curve necessary to have confidence in the results. That said, is there one of you out there who would be willing to do some mod
Jim: Thanks ever so much for the lesson. Like I said, I am no modeler, and you sure told me why I probably never will be....I was never very detail oriented. I'm a big picture guy. I obviously have m
I have a two port six pack that I have relegated to the back bench because of relays not always pulling in. It is tough on amplifier tubes to be running into an open! My rotator has no brake, so cann
I will third the praises of Champion Radio. My dealings with Steve have always been first rate and first class. That said, I am disappointed that Steve has dragged this to the reflector by banishing
I well recall the first time I was at W3LPL to set up a radio for a contest. No ground buss anywhere. I was not surprised nor was I concerned. Not many have a more sophisticated M/M station than does
Tom is of corse correct. My choice of wording was poor. English is my only language, and like many of us I am not all that good at it. I will reiterate....coax interconnection should never be relied
I have a very old American Beauty iron I use only for PL259's.It has a wood handle and cloth covered ac cord. I suspect it is a minimum of 200 watts, and I let it heat up for 30 minutes or so before
