YB400 Mute Mod 2 Mistake!

YB Mute 2 (Re-worked)
This replaces YB Mute Mod 2. This adds un-muting to the auto scan.
(You need the first mute mod for this to work.) This  is all you need to do:
The bottom right  post on the SSB switch wired to the botton of the 153 post.
(below and left of the SSB switch posts) That's it.
 For those of you that did the original mute mod 2, please note and UN-DO this
part: There is a big silver rectangle cover in the middle when you pop the back
off. To the left top hand corner there is a pad numbered 105. Directly below
it, there are two pads. Between the two pads  connect a 22K resistor. I put a
piece of electrical tape over the top right hand corner and bent the resistor
flat on top of it. You can experiment with different values. If you just jump
the two with a wire or solder, you can here the stations go by but it never
stops. I found the 22K stops at medium to weak stations . This is un-necessary
and may interfere with reception. Sorry for the mistake.
