Hi,
not sure if the -bb supports attachments but will give it a try.
I have images of the control station complete with 1970's computers, and the
receiving station.
Nice picture of the antenna array which appears to be four crossed yagi's in a
square, each one has 8 pairs of elements.

Hi Group,
I have finally order the fibre glass pole from Moonraker of all places and
am awaiting its replacement after being damaged in post!
Anyway, I have also received and played with my new shiny LVB tracker to
interface to the G5500 and have a couple of questions that may you guys
could help me with!
a) I have calibrated the rotator with the G5500 and it would appear at 0
degrees on the LVB tracker, the control box is at 0? If I use the controls
on the control box it moves about 2 degree to the stop point. Is this normal
or have I missed something as I have recalibrated several times!
b) The tracker has a USB interface and uses a virtual serial port to
communicate with, but it seems to disconnect quite a lot when using NOVA
during the testing?
c) What are the recommended settings for NOVA as I am not sure I understand
them 100%! I know it uses the G232A command set and does control the
rotator, but I am not sure I have set the interface section correctly.. Do I
set the maximum azimuth to 450 and leave the azimuth setting to 0-360?
Sorry for the questions, but I know how to use it once its been working,
just never had to create all this from stratch.
I have checked the archive on AMSAT-BB and not found much to help, although
some hints to actually get the rotator talking did come from the group!
Many Thanks,
Chris Bloy - M0DQO

Sorry that sentence is suppose to read "the control box isn't at 0 degree
but at approx 2-3 degrees!"

Hi Chris,
Good for you! I'll give some quick replies below (not all points, just
some...)

Have you done the needle calibration as described in the G-5500 manual?
That is important, too. If I can get things within a deg or 2, that's
usually about the best I can get...so you might be "there."

A few months back I removed the USB interface and installed a MAX232 chip so
I can use a "real" serial port. It is MUCH, MUCH more stable. It's
bullet-proof like this, basically. I too had port issues using the USB
interface; I urge you to move to serial if at all possible.

Suggestion--move to SatPC32 so you can have full frequency control AND
tracking ;) I loved NOVA in its day, but without frequency control it
falls off my list pretty quickly...
