After successfully adopting your ideas about a self-made dish in the
ground, we try now to build some kind of signal-detector. Do you have
any idea for our students. It should really low cost.

Dr.Dish:
If your receivers are without AGC-terminals, here follows a passive,
handheld solution. Its not a proper schematic diagram, but should be
understandable:


O signal-input----------I Condens.I----->I diode
---------[variabl.resistor]--
 I                        I
I                 I          I                            I
 I                        I
I                 I          I                            I  +
 I                        Coil                          ^
resistor  condens.              meter
 I                        I                              diode
I          I                            I
 I ---------------I--------------------- I ----------I
------I-------------------I

Since the detector is passive, you should conntect it to the lnb through
a splitter.
Hopefully this funny drawing comes over!
