Topband: Receive ant - binocular cores

[tony.kaz at verizon.net]

I use BN-73-202 cores for my receive antennas - Pennants, BOGs.

Finally getting time to check out my receive antennas. One BOG was very low.
The BOG transformer was broken. I mean it was totally destroyed. The largest
piece was 1/8" long. The primary and secondary wires, #30 were intact and
neither open or shorted. The wire looked pristine. Any ideas what could do
that to a ferrite core? Any reason I should change anything other than just
wire another transformer?
