I have a FTdx560 (very similar to FTdx400) whose 15M operation is dead.
I have tracked the problem down to the band crystal. I tried injecting
the necessary frequency (26.72 MHz) into the rig's oscillator and the
rig came to life; I tested the bandswitch contacts and there was
continuity to the crystal. Therefore, I really think the xtal is the
problem.
Anyway, I would like to find out what the technical parameters are for
the crystal before I order a replacement. If someone has a parting-out
FT400/FT560 and could take out the xtal, that would solve my need too.
Yaesu I'm afraid has long since forgotten about the rig, and could not
help here.
