Thank you for reading this. I'm trying to devise an equation to correct the rotation of my non linear rotator. It's correct in the middle of its range but out at both ends of its travel. I asked this same question ten years ago and someone kindly told me about a simple Window application that did exactly want I wanted. I have searched through my e-mails back to 2000 and cannot find the reply. Can anyone, once again, suggest a suitable Windows or a Linux application? -- Regards, Phil

F/S KLM CP 145/435 yagi's
by w6zkh＠comcast.net 14 Mar '10

14 Mar '10

To my AMSAT friends........as some already know, I am having to move from this QTH, where I had unrestricted antenna locations, but, having to move into a fairly new subdivision , I dont have the room for these antennas. Looks like I am going to be restricted on an Arrow on a RS Tripod at 6 ft. Anyway, I have these older KLM Cross Polarized yagi's with Polarity Switchers, the 2M-14CP and 435-18CP at the unbelievable price of $100 !! I paid $200 for them last year. One stipulation though.....ah ha, here it comes........you have to pick them up, no shipping, ASAP . The 2M can be broken down into 3 sections and the 435 into 2, so a pickup can haul them. I live South of Fresno, in the middle of California (sorry)... These yagi's have been working well for me at an height of 15 ft above ground and the Polarity Switching works great, especially on FO-29. If you or you know of anyone looking for a great setup for the birds, contact me ASAP , so we can set time/date. Attached is a picture of them in the air........sorry, the AZ/EL system doesnt go with it... Contact me at 559-737-3411 John W6ZKH

APS-1 for sale
by Alan P. Biddle 14 Mar '10

14 Mar '10

Hi, Some time in the dim past, I bought a Mirage/KLM APS-1 Antenna Polarity Switcher from a local ham who bought a nice 1990 vintage satellite station but never got on the air. They were designed to switch the antenna circularity of KLM satellite antennas, plus provides a regulated DC output, 5-13 volts. Should work fine the an M2. The front has two push buttons labeled 144 and 432 and a power switch/voltage knob. The back has two phono jacks for the circularity, and two terminal jacks for the adjustable power. It uses a wall wart with a standard 2.1 mm jack. The input power is 11-15 volts DC @ 500 ma. It is over 20 years old, but truly looks new, with no scratches or dents. The original parts list and instruction sheet are also included. The original wall wart is NOT included, but there is a compatible one included if desired. Pictures and a copy of the instruction sheet available on request. This works perfectly, but is more of a vintage gear item. $25 firm, including shipping, North America. Please contact me off list.

Fractal Antennas?
by Dave Marthouse 14 Mar '10

14 Mar '10

This seems almost too good to be true. Keep in mind that I'm not an engineer. Maybe this technology could be used for future amateur satellites, wider bandwidth, more gain, less space, etc. http://www.fractalantennas.com/ Dave Marthouse N2AAM dmarthouse(a)gmail.com

Re: Playing With Lightning
by Wayne Estes 14 Mar '10

14 Mar '10

If you live in an area prone to lightning (especially Florida) you should invest in a good ground system and single-point ground panel with surge suppressors for all antennas, rotor/control cables, AC lines, and internet/phone connections. It's very costly and a lot of work to install. But the alternatives (destroyed equipment or even a burning house) are even worse. The information and required equipment is out there.
