Because with 110W, who cares if the repeater is down? Just drive for somewhere "high enough" and you'll be heard for miles around.

Short answer on the output issue: 100 uF capacitors on both audio leads in series with the audio path.

From the Saber +5V bus to the Option sel connector, there is a 20 kohm resistor in between.

Bad PA modules were a common drain in that line. The other thing is that any secure-capable radio equipped with a crypto module will draw power to keep the key alive, even if no key is loaded.
