Subject: Re: [amsat-bb] Rotor Adjustment
Hi, Les
The 500 ohm potentiometer inside the rotor unit has one end
connected to the positive DC voltage in to the control box and
the wiper is connected to the meter via a adjustable trimmer.
The other end of 500 ohm potentiometer is connected to the
negative DC voltage in to the control box.
If the negative end of potentiometer get disconnected from the
negative in to the control box because of an open circuit than the
potentiometer functions as a reostat in series to the meter and the
dial goes all the way over the max right position no matter the
motor is rotate in any position.
The open circuit can be in the wire connecting the pot to the
control box or the pot itself.

Hi Andy
I have the article " A LINEAR TRANSPONDER FOR AMATEUR RADIO
SATELLITES " written by Dr. Karl Meinzer DJ4ZC and published in
VHF Communications 1/1975 describing in great details the mode-B linear
transponder actually working on board of OSCAR-7
This artiche with all schematic diagrams is 16 pages long and if you or any
other is interested on it I can scan and send it via email to everybody in
two or three different messages.
Please let me know
