[Premium-Rx] WJ-8711 / HF-1000 DB-15 Connector Pinout?

[CalvinF15]

Folks,

I have a pair of WJ-8712T radios that use the DB-15 audio connector that is apparently common to the 8711 (non-A version).  Can anyone help me with a pinout of the audio out?  I understand that the following terminals are available on the 8712A:

Line A: High/Low/center-tap
Line B: High/Low/center-tap
Speaker: High/Low
DC audio
Mute (in)
Squelch
RSSI
Ground

I assume the same terminals are available on the 8712 (similar to 8712T).

Thanks for any help.
