Satellite Analyser
« on: June 25, 2012, 01:48:43 PM »
Hi,

I would like to start a project building a satellite analyser controlled by an arduino.

So for the start i need (generally):
1.  Arduino mega board + an 3,2" TFT Screen.
2.  A satellite tuner. I can remove one from a spare sat receiver. As i read  their PLL is controlled by I2C interface so you can select the frequency and they provide demodulated I and Q baseband signals.
How can i use these signals?
Do i need a decoder chip?  After some search i found the TDA 8044 but i cant understand how to use its outputs.

My thought is to control the tuners frequency with arduino, scanning the one of the 4 bands and show the lvl of the frequencies as a signal on the screen.
