Tod, I had a problem with a TH7 and SWR variation after rains. After taking down the driven elements (while antenna still on tower), I disassembled them, including the traps. The traps were full of d
Just to warn people, another big ripoff is Kenwood Parts, aka East Coast Transistor, located on Long Island. I ordered a small part ($6.00) for a Kenwood VHF radio. They charged me an additional $6.5
<snip> <snip again> Steve, Since you refer to my 57 cents, I feel obligated to respond. The company made (or should make) their profit on the item sold. The part in question was a "screw kit" consist
Lots of antennas work better than you expect on the "new" bands. On 17 and 12m, I use my Cushcraft 40-2CD 40m yagi. I had no trouble working any of the DXpeditions. On 30m, I use my 80m slopers. I do
Oh yeah? So why do LPL and RM still beat be out 99/100 times during peak band openings? Barry W2UP -- Barry Kutner, W2UP Internet: w2up@mindspring.com Newtown, PA Frankford Radio Club _______________
For me, modeling was very helpful and was very accurate. The purpose of my modeling was to design an antenna system which would minimize interactions between antennas in a one tower SO2R setup. My go
Amazing things are possible on 80m with small antennas. Take a look at: http://w2up.home.mindspring.com/80m-indoor-ant.jpg (scroll down for back of card with description) This QSO occured during duri
Similar here. I got my reels at Agway, same place I buy my Beverage wire (17 ga galvanized steel - under $20 for 1/2 mile). Barry W2UP -- Barry Kutner, W2UP Internet: w2up@mindspring.com Newtown, PA
Bob, Jumper 4 to 8 for CW, or 4 to 6 for CCW, to bypass limit switches. BTW, I have this info written on the inside cover of the manual, so I don't have to remember it :.) 73, Barry -- Barry Kutner,
I just pulled out the manual and checked the schematic. Looks like you are right about that. Sorry abt that! For K4MQG - no need to climb the tower. When you bypass the limit switch, you can do the r
Maybe so, but people don't run their leaf blowers every 20 minutes of every day. Barry -- Barry Kutner, W2UP Internet: w2up@mindspring.com Newtown, PA Frankford Radio Club ___________________________
I have 3 TH7s on one tower - 25, 40 and 76 ft. There are plenty of times the TH7 at 25 ft is better into Europe than either of the 2 higher antennas or the upper 2 phased, on 10m. The lowest antenna
I had a problem with flexweave, too, on my 80m slopers. The strands abraded each other as it swayed it the breeze, rubbing off enough copper to expose the steel core. This rusted and eventually broke
I hate to say it, but property values can be affected: One day, my next-door neighbor (who built about 4 years after I did) and I were chatting. He told me that he used my tower as a way to negotiate
Another material that helps separate stuck and rusted parts is Kroil (means Kreeping Oil), made by Kano Corp. The stuff is supposed to have almost no surface tension, so can creep in between those mi
Hi Richard, I did the alligator clip routine for several years. It gets old quickly, especially in winter, here in the north, trudging outside in the cold and maybe snow. What I wound up doing is buy
Another interesting note on the 80/75m slopers. After switching to Jennings RF1J relays, rather than using clip leads or folding back a ~10 ft section, I noticed that the extra length for CW is short
Why pull hardline through a pipe? Sounds like more trouble than it's worth. Just directly bury it. That's what the cable company does. I have a 100 ft run of 4 inch PVC buried and pulled all my coax
I would put it at 40 feet now and move it to 80 ft in 2-3 years. I have TH7s at 25, 40 and 76 ft. The one at 25 feet frequently outperforms either of the 2 higher ones, even when phased, into EU. My
