DBS small satellite dish systems often have LNB feedhorns capable of
multiple polarizations and/or multiple bands. This is often controlled
by changing the voltage which powers the device. However, some have a
more complex control system involving tones in the 20kHz range if my
memory serves correctly. Is there anyone who has a reference on this
control system, or who knows how it works? I want to use these for
radio astronomy with the USRP and need to know how to control them.
Thanks,
Matt
