[Discuss-gnuradio] DBS Dish Feeds

[Matt Ettus]

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
