hi all ,


the PGA103 is prone to go dead when powered under 5v , it is better to use it at 3V

Conrad,

Mistake on my part. Yes, the PGA103 is the second stage. This was definately dead (dead short) .
Will take the pre amp back to the shack later for more checks.
Chances are if the PGA is dead, then the SKY will be as well.
There is no way I would even attempt a repair. Did try with a single stage pre amp but well beyond
my capabilities and eyesight.
