Are you using this as a voltage divider?

Thanks

Hi Frank,

Ooops.. you're right... the simple version is not posted.... I will
include
it in the next release help file.
You just need the receiver, a capacitor and two resistors... this is all..
no other stabilizer....
I can send you the schematic if you want.

Best regards,
Dan
