The Cushcraft 40CD2 (now the XM-240) seems to play well. I've had one for almost 30, starting out on a city lot, and it helps a lot. Kim N5OP "People that make music together cannot be enemies, at le
I'm a research meteorologist at the National Severe Storms Lab in Norman, OK. I don't do Lightning research but know others that do. Here's what I know from them: 1) static porcupines don't work, 2)
We have a small club that runs 2A with a GOTA station. We run one phone and one CW station on dipoles strung end-to-end in trees. Ends are separated by 30-40 ft. GOTA runs a 43 ft vertical with an SG
I should add that we run phone and CW on the same band without problems. Kim N5OP "People that make music together cannot be enemies, at least as long as the music lasts." -- Paul Hindemith _________
Unless the ferrite material is porous such that water can penetrate the surface, I don't understand their disintegration. I thought they were essentially like glass. If they aren't, and if water can
At our club we make certain that our dipoles are strung end-to-end at nearly the same height. We also make liberal use of common mode chokes on both ends the the transmission lines for each station.
'Zactly. The value of 10-15 dB of attenuation can work wonders. Kim N5OP On 7/4/2017 5:48 AM, Ed Sawyer wrote: I have done quite a bit of "in band" low power 2 radio work. At 100 W, 2 A4 tribanders,
I'll bear witness to the "good connectors, properly installed" aspect of Jim's post. At this year's field day, the GOTA station was running a 43 ft vertical with an SGC 237 remote tuner about 200 ft
This is what I do most of the time. I have a modest BX tower (HDBX48) and it is very uncomfortable to climb because of the X-bracing. In some instances, even if I climb it, I can't get to what I need
Rod's idea is by far the best. Slopers are weird creatures. While you can broadband antennas by making the elements with a large diameter (as in a cage) the mechanical complexity isn't worth it. If t
I misunderstood and assumed half-slopers. Autotuners wouldn't help much! Kim N5OP "People that make music together cannot be enemies, at least as long as the music lasts." -- Paul Hindemith _________
The T2X clamp is made (inexplicably) for 2 1/16 mast. So, you need a 1/32 shim. I went to a hobby shop and purchased some 1/32 aluminum sheet, used it as a shim, and have been delighted ever since. T
You might try tying strips of white cloth at intervals along the radials. That way, the deer can at least see them. 73, Kim N5OP "People that make music together cannot be enemies, at least as long a
FWIW, we have a small General 14 kW NG air-cooled generator with a manual transfer switch. Its RF quiet at any frequency I can hear, from the BC band through 450 MHz. As an aside, we had trouble star

Hi Tim, Im a bit surprised they arent offered as a standard add-on. I was pretty skeptical until I installed them and when I saw the difference they made. I was pretty much blown away! Id never consi

I use a Davis Vantage Vue. Its mounted on the side of my tower and uses spread spectrum RF comms between the instrument pod and the display station. I shunt feed the tower on 160 m at 1500 W. Ive nev
