Wire nuts, special connectors in place of the terminal strip - wouldn't have any of that here, that's just a lot of extra work and cost, and limits the flexibility of the system. A simple 3 foot pigt
Doesn't cut it here, especially in winter. You haven't the -40C to contend with so it might work. At the very least, I install a 6 vac filament xfmr in the controller cabinet to boost the ac for the
I believe the extra downward forces exerted from the guying are less likely to crumple the tower than the equivalent side forces exerted by wind pressure. Within the boundaries of common sense - 7/8"
Yes, I have noticed the exact same problem with the M2 40m yagi. I helped another local amateur install one (at the top of a small stack, so a big job to change it!). After FINALLY getting a decent m
The KLM log is rated at 12 sq ft and weighs 100 lbs (7.2-10-30version). A friend here locally had a similar problem with his G1000 rotor on a Sommer beam( quite large, has coverage from 7 to 30 mhz)

Up here, far from salt water and sail boat supply houses, good pulleys are hard to find. I use the National brand found in most hardware stores around here for general tower work and some antenna app

Well, it's not any secret - I am one of the owners of Alfa Radio and we market the AlfaSpid in North America. As Steve K7LXC mentioned here quite some time ago, Alfa Radio is owned jointly by a group

Yes it uses the reed and magnet. Most of my runs are very long, but the longest run of over 1700 feet just uses thin 22 gauge telephone wire (unshielded) to return the pulses and it counts fine. It's

The latest controller will emulate Orion, Yaesu or HyGain thru the serial port. I have seen a USB cable as well. Earlier versions of the controller can be upgrading by plugging in a newer version chi

The DCI filter is the one to get. I know various hams who have tried the notch route and other simple filters with no luck, but the DCI filter cured the intermod problem. I have several in use myself

You may be missing a few teeth in the ring gear when it is in that direction. Very common problem. If lightly loaded on the test bench, it may turn fine. 73 Don VE6JY -- AlfaSpid Rotators at: www.alf

SPID not SPUD... If your feedlines don't allow 720 degrees of revolution, you can always set the programmable limits to a lesser value. In most cases one should be able to (re) design the rotor loop

To get sufficient space between the tag lines, yet allow them to be untied from the center is simply a matter of tying the knot in the center and running it out along the boom and then dropping it ov

If you have the proper soil for the original called for base, I'd say your alternate suggestion is quite adequate. I wouldn't loose any sleep over it. 73 Don VE6JY ___________________________________

a couple of points: - it is nice to have the guy wires 5 feet or so down from the top (much easier to maneuver around the top), provided the tower and wind load are compatible. They should be in your

I'd venture to say that any "Bush Hog" or similar mower in the junk yard is there because the gear box is broke! Everything else is fairly minor to repair/replace except that! But one never knows why

It will depend on the yagi, but from experience the OWA design, with the close spaced first director, can be tuned near the ground - pointing up in the air as much as possible is always advised - wit

Cameras are a great way to see what's going on up the tower. I have been using the small wired, inexpensive (30-50US$ range) pinhole type cameras - called B&W "spy cameras" in some ads. The b&w camer
