Default Lightning damage

My micropower ISM/HiFer "beacon" got fried Sudnay morning by lightning.
We had late 4rth of July fireworks show at 6:30AM and I found out
Monday
about the damage. The friend's house where I had my unit operating
expereinced
several direct hits. There was damage to his both of his ~100' Oak
trees,
every electronic item in the house was toast. Most incandescent light
bulbs
were blown. The trees will have to come down.

He said the first bolt hit one tree and about 5 minutes alter a second
bolt
hit the other tree. A third bolt hit the power pole/line feeding his
home and
the power transformer exploded. It sounds like he had a fun morning.

My unit did not get a driect hit, no burnt parts, but every fuse was
silver
plated and ever semiconductor was shorted. The PIC that controlled the
unit was the only part visibly damaged and it had a hairline crack. The
Rio
MPP-300 display shows some segments but it won't play anything.

The 13.560000MHz crystal survived so I might build a simple CW unit.

I am lucky that it survived a year and have no complaints, the only
part
I regret lossing is the electronic 63dB step attenuator. Those are a
little pricy.
