After serving me for many years, my good old keyer, microham mkII stopped keying last night.
Of course this happens at the least convenient time, during a contest.
I got an idea of where the fault lies, but if any of you guys has a schematic if the MKII lying around, I would VY much like a copy.

Failed Microham MKII

Couple of months ago high wind gusts bent a support tube in my tower.
Well, yesterday was repair day. Here are some photos.

improvements: Support tube is now made of steel, before it was of aluminum. Also, notice the second support bearing in the middle. Hopefully this improvements will make it hold.
