I have a friend in Thailand who recently zorched out L5 in his 77DX.
Believe it or not, a small lizard got into the tank circuit and when
he was tuning on 80 meters, L5 got extremely hot - to the point of
cracking both of the torroidal cores! Does anyone know what specific
cores were used or if not, what the approximate value of inductance
that L5 should be? I assume these are iron powder cores. I'm trying to
help him remotely or perhaps send him a replacement
If they are broken in two (or more pieces) I have a friend that
swears that after gluing broken
powered iron cores back together they work just as good as new, after
being epoxied back together,
Clamp them together while the epoxy sets. (a radiator hose band might do)
