Great radio, a good cleaning with Deoxit brand
contact cleaner is a good idea, just the smallest
drop is needed. also lube the bearings for the
cooling fan in the final cage.
if you need manuals, d/l here no costhttp://www.n6wk.com/kenwood/http://groups.yahoo.com/group/TS-520_820_530_830/
don't want to be a wise guy, please use caution
when working inisde these hybrid radios,
there is 400 to 800 volts inside !
