Re: AMSAT-BB Digest, Vol 2, Issue 453



Mounting The G-5500 elevation rotor in any way other than vertical will
cause problems as the condensate will not have a way to get out and will
ruin the unit.

The coordination with actual direction is easy as it just involves pointing
the antenna correctly after mounting the unit any way you do. I am not sure
if another drain hole drilled would solve the problem of drainage.

Incidentally if it is a new unit, please do replace all the bolts holding
the two halves together with SS Allen Key type bolts as after sitting in the
open the regular screws are very difficult to remove with a regular
screwdriver- I have had practical experience on this!

Hi,

Beware mounting it at 90 degrees to the vertical. It has a drain hole  
at the bottom to allow for the drainage of condensation when mounted  
on the 'U' bracket.

As David already mentioned, you may create drainage problems by mounting 
your elevation rotor horizontally...  if you want to block the existing 
hole, and drill a new one in the new "bottom" of the rotor, you may be okay,

but "you pays your nickel, you takes your chances".

As far as "setting" the antenna position, the controller doesn't care how 
the rotor itself is mounted:  when the rotor is at the zero degree limit of 
its travel, you mount your antennas pointing at the horizon, and you have 
established the zero degree position.  Everything is relative from there.

   Either my S-Band D/L is not working or the sat never shifted into the new

mode. Comments from the bb.

Hi Bruce,

Well something's working.  I just finished the 03:30z pass here.  I heard a 
couple of partial calls on the 2401.200+/- ghz downlink - VE7C?? and another

partial suffix.  The pass started with someone with a nice clear signal and 
a Spanish/Mexican accent.  There was a call sign, but I didn't catch it.

However, I was not able to get into the bird myself on 1268.700 +/-.  Not 
even a change in static, even right after I heard an apparent full-quieting 
"kerchunk".  This is with my new and unproven helix antenna, so I have one 
too many unknowns here to know what the problem is.  I did follow the same 
doppler process on the L-band uplink, and also swept the general vicinity, 
so that shouldn;t have been the problem, and the pass peaked at about 50 
degrees.  Nothing back from my uplink.

Anybody else have a go at it?

Greg  KO6TH.

Nothing heard on the 05:10z pass.  Only a 10 degree pass, but off in a 
favorable direction (no trees).  Downlink carrier was very weak and barely 
there, if at all.  Keying up on 1268 had no effect, as before, though I 
doubt I would have heard anything even if it had..

Anybody having success?

Greg and
I will try to make every pass available on 7/10.  I have been praying to the
L band gods.  We'll see what happens.  10 watts-40feet hardline-40 turn

Hi All
I am getting my new 30 ft tower and wish to changeover from RG213 to LMR600 
I have, for the Vhf and Uhf cross yagis. Will be installing my masthead 
preamp too and its going to be convinient to use a short length of thinner 
coax patch upto the Beams near the AZEL.
So any tips , suggestions on the type of thin cable RG-58 or RG-213.
Thank you
Best 73

:o)  Vhf & Uhf cross yagis, Masthead preamp for Vhf, AZEL with digital 
readouts all  home brew  ;o)
