  Does anyone know if when you have the preamp button set, and it sends 
+12 vdc up the antenna jacks, is the voltage dropped when you key up on 
one of the antenna ports (ie, preamp on, + 12vdc is sent to both 144/430 
and you key up on 430, is the voltage dropped on the 430 side?)

     Getting back on the birds, and getting used to the 821,
