[ICOM] Internal tuners

[Dwayne]

Hi Name is Dwayne  (ve6qx).. I'am trying to understand why its not a good idea to have the internal tuner in my Ic-775 Dsp on when driving a pair of 3-500's  grounded grid..  The reson I want to do this is because on 10 Mhz.  the input circuit to the amp has a s w r of about 1.9,, because the amp was built before 10 mhz. became popular to use..  They used the same inpuit circuit for 10 mhz. as 14 mhz.    Anyone who can offer a good answer please..
