Re: LF: Re: IC718 problem

Hi Dave, Jim,

It's the spongey rubber-VCXO used in the IF shift/ passband 
tuning that's by far and away the worst drifty thing in the 
'735.  More trouble than it's worth to try and fix, and which 
then leaves the radio with fixed bandwidth. Sigh.
Other than that, great little radio.

        Cheers,

                Steve
