Intermitant problems ARE hard to fix. Hard to fix it if it isn't
broken. I have a KX155 and it has been pretty solid. Also, avionics
techs KNOW them and like to fix them. They know how to fix them. They
are built to be repairable. They have individual components that can
be changed. You don't have to "swap out a board".

70% of failures in electrical equipment are CONNECTIONS. I'd look
there.

We're having some problems with our KX-155 where it intermittently stops
navigating. Several attempts at repair have failed. A friend has a KX-155 that
won't transmit. Another friend had a series of repairs on his KX-155.

The conventional wisdom seems to be that the KX-155 is the gold standard in
NAV/COMMs, but I have these anecdotal gripes. Are they the best there is?

Thanks,

Dave
