DR-M50 Mods
 

This modification is very confusing and I think is only for the Japanese version.

I present a modification here to you has to make on the DR-M50 to unsling it. This modification makes it possible to open the bands 130-174+300-340+400-470+800-1000MHz.

On, I guaranteed well nothing, but at me her place goes very well….

CAUTION: TO BETTER UNSOLDER COMPONENTS CMS IS WORTH BEING WELL TEAM AND TO BE ACCUSTOMED TO HANDLING SOLDERING IRON!!!

I deliver the explanation in Japanese to you because I suppose that the dessinse is enough has him same. BUT, on my apparatus, version DR-M50H, resistance not here R420 are R55 and are located in the part not VHF and not UHF….Moreover I do not see a CPU at all…

Note to finish that the explanation Japanese some indicates that the point locates under the apparatus has the place notes “D”, right
 A the vertical, end of the turntable must be SODA with the point which is right with the top of him when one is face has the apparatus.

Good realization and good courage… REMAIN CAREFUL!!!
