[Yaesu] FT1000MP AF out affected by AF Gain control settings

[Mike Ruttenberg G7TWC]

Yes there are 2 ports on the rear, EXT Speaker and AF Out.

Ext Speaker is connected to the AF Gain control, and is supposed to be, so no problem there.
The AF Out is not meant to be connected to the AF Gain control. On mine it is. In which case it is acting exactly with the EXT Speaker control, 
which is no good to me.

Due to this issue, the problem is that I have to have the headphones on at 75% volume in order to get enough of a signal to drive the AF Out 
line feeding my soundcard for data mode work. The AF Out level is supposed to be constant and independent of the heaphone/AF Gain 
volume. It isn't, as indeicated above and several times below, so when trying to do data mode the rig speaker is blaring, or the headphones are 
blaring (whicher i choose to use). It is unpleasant to be in the presence of the rig when the volume is at 75%.

If you say "well don't turn it to 75% then" then I don't get enough volume to drive the soundcard for data modes, which is what I would like to 
do.

So back to the original issue: Has anyone come across a situation whereby the AF Out levels are driven by the AF Gain control and thereby 
able to assist me in finding out whether a mod exists to make it like this, in which case I can reverse engineer the mod so that it doesn't happen 
and does what it is supposed to do according to the instructions.

Thanks
