[Yaesu] FT-1000 MP problem

[John Lockhart]

Hello Markus,

You might want to remove the top cover off the MP and "wiggle" the jumpers
that run from the antenna switching circuit board to the two SO-239
connectors on the back.  See if you can cause the problem to occur. Also
check for a cold solder joints on the SO-239s and on the switching board.
Lightly tapping on the relays on the switching circuit board may also narrow
down your search.

GL and HNY!

73,

John  W0DC
