Well finally caught it while it was acting up again!

Had to add an audible alarm to help me catch it.

The 1st L.O. (1440Mhz)  dies completely and also the 20Mhz TTL front
panel output dies.

Both the 1440Mhz and 20Mhz are derived from the 180Mhz signal.

So now need to see if the 5Mhz input to 180Mhz multiplier  is OK during a
failure.

That should point me to the correct subassy.

Cheers,

Corby
