[Yaesu] FT101E MJ voltage readings!

[W5HTW@att.net]

Hi Gang,

I have a chart for operating voltages on various pin numbers of the FT-101E boards and modules . Down the side is pin #, that, I can figure out. Across the top is "MJ" number. How do you correspond "MJ" # to the correct board identification. I must be missing something very basic. Or, is this some knowledge passed along via DNA to Yaesu owners? What does "MJ" refer to? Yaesu identifies it's boards by PB1056, PB1547, etc. I'm missing the Rosetta Stone linking the two.

Thanks in advance...

You noticed that, huh?  Well, it only took me about a year to figure it out, so don't feel like The Lone Stranger. 

Check the schematic.  As you read the dotted lines ...  For example, where it says (PB-1315  AF UNIT) right next to it, it says MJ(4)    So PB1315 is MJ4.   All of them are identified on the schematic, but that is the only place I have ever found.  

PB1184A MOD AND OSC is MJ5.   Etc.

Why dey do dat?  Not even the Shadow knows, not even, in fact, the Japanese Shadow.  Probably PB was harder to say than MJ??   Maybe MJ is a Japanese acronym for ... well, we won't get into that.  Could be short for Made In Japan?  

But it's there.  And ONLY on the schematic, as far as I have ever been able to tell.
