I recently obtained a pair of KLM yagi's for satellite work. They both have the
KLM polarity switching box mounted and wired up. Since I havent put them up
yet, and not well versed in the subject, I got out my ohm meter just to see
what was what on this item. I noticed that both driven elements
Hi Myles
Just wondering if anyone out there using the LVB, could drop me a
line and let me know their opinions and experience with it
I can only say good things about the LVB Tracker ;-)

The relay switches the coax between either end of the phasing line.

Our mini WAS-pedition to Wilmington Delaware FM29
ended with the 7/12/2009 1305-1316z AO51
pass which was only 11 degrees in Delaware.
In just two days approximately 85 different
callsigns were logged (including 4 with
KD4ZGW who operated from his 18 wheeler in
DN90, EM38, EM29 and EM65). If you
There have been a couple of recent posts about a G5500 voltage drift issue
and some solutions. I'd like to thank those gentlemen for the posts and the
solutions. I am in a unique position to be able to work with nine G5500
rotors side-by-side in preparation for the Teachers Institute II that I
Hi LeRoy,
Which version of gpredict are you using? The one that is included with
Ubuntu? That version is very much out of date and did have several bugs
that could affect pass predictions. In particular the time controller
function was very immature back then.
Did you try the predict pass

is mentioned in the latest issue of SatMagazine
The July/August issue of SatMagazine covers the Australian space program and

Hi Mark, WA8SME
Sometime the voltage regulators tends to self-oscillate in a very low but
very wide frequency band.
In this condition the regulated voltage is unstable not clean and dirty as
can be seen using an oscilloscope.
This problem is well know by the microwave people when they try to
Hi John, W6ZKH
The 2 meters KLM antenna uses two crossed folded dipoles wich are spaced 1/4
wavelength in air over the boom so that to get circular polarization no coax
delay lines are necessary.
Each folded dipole has a wounded coax balun with ratio 4/1 wich is made with
1/2 electrical
