[AK-VHF] IC 260A service manual?

[Edward R Cole]

Ron,

I am no help for you, but why are you concerned about LSB on 2m?  As 
far as I know all 2m-SSB is done on USB which you indicate tunes 
properly.  Finer tuning than 100-Hz is desirable but may not have 
been designed back when the IC260A was built.  You can probably get 
along OK with that.  Does the radio have RIT or XIT?  With RIT you 
can fine tune the receiver which probably is needed.

I have a used FT-736R which is supposed to switch from from 100-Hz 
steps to 10-Hz but is non-functional on this radio.  It has a 
clarifier for the Rx, though.
