I need to replace a rotary switch on my TKM Com 11/A radio. I inadvertently
broke the shaft while exiting the airplane. It is soldered to a pc board in
13 locations (12 around the perimeter and 1 in the center. I have no
experience with desoldering things from a board. My questions are as
follows: Is this a particularly difficult thing for a novice? Is there a
tool I should purchase for desoldering? If I really need to farm this out,
are there any suggestions where to find someone capable of doing this?
Thanks for any and all suggestions.

I have used a product called solder wick. It's a copper wire mesh that absorbs
heated solder. I have also seen vacuum devices to extract the headted solder.

If it=99s a well made circuit board, you have a good powerful solderin
g iron with the right size bit (not too big, not too small) and know how to u
se desolder braid and solder sucker, and are ready for eventualities (like a
re equipped to snip the last couple of pins that won=99t come away wit
h the rest of the switch) - then it=99s straightforward.
If not then you=99ll start to lift tracks and damage the board.
An expensive piece of working equipment is a bold starting place to learn re
work techniques.

Probably not a big deal for an experienced electronics tech, but I'm not
sure I'd advise that as a novice exercise. Might be worth asking at your
next EAA chapter meeting if anyone there is a HAM operator (a lot of
pilots are HAMs), or if anyone has experience with board-level electronics
repair.
If you're determined to do it yourself, and you have the new switch in
hand, you might be able to cut the individual terminals on the old switch.
If you can do that without damaging the board, removing individual pins
from the holes becomes a lot easier.
Again, not a beginner level task.
