Steve,
I understand your frustration with the latest replies.???
I am not sure if you want to use Ant 1 or Ant 2 in the situation you described.
Assuming you want Ant 2, If the amp is turned on, (which it would have to be in order to select an antenna)? and even though it is in bypass/standby, perhaps? it automatically ? detects a frequency,? and if so, maybe it is defaulting to Ant 1??
