[Hallicrafters] R-274 Band VI Update

Hi Jacques, 

The coil only has about 6 turns on it wide spaced so no possibility of a
short there. I did look at the slug in the coil and it appears intact and
does "tune" the resonant freq with adjustment.

I re-read the theory of operation and it appears that band 6 functions just
like the other higher bands VFO signal plus 6mc.

I'm about to go work on it now - we'll see what happens tonight....

Tom

Hi Tom,
You could have a short between coil turns or the ferrite slug within the
coil (if there is one, say) is the bad one.
Are you sure that this top band do not works "in reverse" , meaning having
the LO working BELOW the received frequency by the value of the first IF ??
Just ideas.... remembering that your set was beaten up before !
