One other oddity. Before I power up the radio, the amp is drawing zero
current. As soon as I power up the radio (on RX), the amp starts drawing
180 ma, whether it is switched on or off.

(=A0=A0Impossible. The amp has no input for the powered condition of the
radio (receive). )

Wrong -- it's very possible. That is a MOSFET

amp with no power switch. A bad combination

to be sure, because as long as there is

source-drain voltage, any kind of signal can

drive it to some extent. It's possible that C1

could be shorted (after all, it's only rated for 50
volts) and the output of the radio have a DC

component. Or if D2 is blown (a 1N4148

passing 3 watts -- yikes!) D1 will hold a nice,

steady DC bias on the MOSFET. There are a

lot of possible scenarios for what he is

describing. What -is- impossible is for you to

think before you demonstrate your ignorance.



Heal thyself. In the first manner, there is no need for projected
disdain and insult towards one who you disagre with. Keeping wiht the
subject of the group and discussing the electronic possibilities that
may or may not be wrong without insult is a good way to try and lose the
deficit in communication you portray that has you becoming an insultive
jack ass to a poster in a group for merely offering a differing point of
=3Dview than yourself. Your level of intolerance for differing views
llustrates your true level of intellect and communication skills.
The chance of probablility you offer concerning your weak input
concerning all three amps having the same short is ridiculous, like most
of your ignorant and abusive posts that were responsible for you having
no choice but to subscribe to a pay access in order to access the group
in the most obsessive manner.


The likelihood of one individual being correct increases in a direct
proportion to the intensity with which others try to prove him wrong
