[Discuss-gnuradio] Sharp BS2S7HZ1204 tuner

[Marcus Leech]

I spent last winter playing with the Sharp BS2S series DBS 
direct-conversion quadrature tuner module.

I have full data on the module, and was able to use it in the following 
project:

http://www.propulsionpolymers.com/radioastronomy/seti_receiver.pdf

The unit that I use is shown here:

The unit is programmed via I2C, with the AGC voltage set via an analog 
input between 0.8 and 2.7V.

It's a direct conversion quadrature receiver producing I and Q outputs 
stretching from
 DC-<programmable bandwidth>.  The bandwidth is programmable from 2.5 
to 20Mhz, and
 the frequency is programmable in increments of 62.5Khz between 950Mhz 
and 2150Mhz.

Since this is an I2C unit, and Gnu Radio already has I2C routines, it 
should be fairly straightforward
 for someone to take the routines that I wrote for the above project 
and integrate them into
 Gnu Radio.

I also have a .PDF of the datasheet for this device somewhere.

I was able to get the tuner as a free sample, but even in 1s and 2s from 
the local distributor, they're
 only about CDN$12.00/apiece.
