I am too. I don't know much about the durability of ferrites, but I
am envisioning yours as rather thin and possibly delicate, and a year
or two in a northern USA winter might do a number on them. Then
again, I haven't seen stories about problems with ferrite core damage
due to weather. I wouldn't be surprised if some ferrite formulas are
more sensitive to this than others; and that the larger cores used for
transmitting might be more durable.
Besides, if it was lightning damage, I would expect more outwardly
visible signs, like the whole thing being blasted apart.
But we do get some interesting winter thunder-snow storms up here from
time to time.
A connection to your transmitting tower isn't necessary. If that
tower was hit, anything and everything within at least a few hundred
foot radius could have been affected.
