Tennadyne had some 40-20/10m logs on their website, but they are not there currently (at least I didn't see them). I contacted them a couple years ago and was told that there didn't seem to be any in
For years, an osprey has maintained a nest on the top of our radio club's 180' tower. It appears that a red-tailed hawk has claimed the nest now. We need to do some antenna work on the tower, just do
I've encountered the same thing- I drill out the center pin on the connector and they work fine. Doug K4AC -SNIP- _______________________________________________ _____________________________________
My Tri-Ex LM354-HDSP has a delay circuit for the up side and one for the downside. As the time is set by a fixed resistor, I'm not sure what the intended delay is, but I'd estimate it to be around tw
Ed: The other thing to check is the cut-off switches. The typical wiring calls for the cut-off switch to be normally closed; when it is contacted by the tower, it opens and shuts off the power to the
I've been using LMR-400 with my crankup tower for about 5 years, including the rotor loop. I've got about 10 runs bundled into a large umbilical cord with the rotor cable, a heavy cable for the 24V t
Mickey: All of my 10 or so runs of LMR-400 are grounded at the top of my crankup. Although the sections are indeed suspended by the wire rope and sheaves, the reality is that at least one, and usuall
Does anyone have a manual for the Yaesu GS-23 RS-232 board for the SDX series rotator controllers? I found a text only version of it online, but that doesn't help with figuring out the baud rate sett
I've got a 2800 rotator and a controller with a GS-23 installed. The controller is set up so that when the rotator is fully ccw, it is at 180 degrees (south). When fully cw, it is at 270 degrees. Usi
The common coaxial surge protectors use gas cartridges for protection. It takes hundreds of volts to cause the gas cartridge to fire and conduct to ground (off the top of my head, I think it is aroun
The Yaesu rotators use worm gear reduction to turn. By design, worm gears can't ordinarily be driven in reverse by the load. So the bottom line is that no additional brake is needed. As to gentle sto
I've got a crossboom made out of two 4' pieces of angle iron bolted onto my crankup (about 7' long total) with U-bolts about 18" down from the top. Each end has a short section of angle welded on to
I don't know about Dino's, but if you need a climber K1TO (A1 Tower Service www.a1towerservice.com) does great work. Doug K4AC _______________________________________________ ________________________
I have one of the later Tri-Ex LM-354HDSP towers. The worm gear reducer is a Hub City 0220-05019-300, Style W300, Type A, 40:1. This is a long obsolete reducer. Can anyone tell me the reducer current
