[ICOM] Icom 706 MKIIG external speaker connection question

[Charles Zumbro]

Hello - I have a 706 MKIIG used as a backup rig for my 756Pro III.  In
general the 706 is easy to use, but I have been unable to make an external
speaker work from either the front or the rear speaker connectors.  I have
tried the "Phono - Speaker" switch on the rear of the front panel in both
positions without success.  The front panel connector works fine with
headphones.  When I plug in an external speaker into either connector, the
internal speaker shuts off as expected.  The external speaker is an Icom
SP-20 which works OK in all modes from all ports;  it is used regularly with
the Pro III and a 2 meter rig.   Does anyone have any idea as to why I
cannot get external speaker output with the 706?  

I recently purchased the Pro III.  I have a low mileage mint 756Pro II for
sale and will accept a reasonable offer if anyone is interested.  

Thanks in advance,
