A new encoder is only $160.

Well, I finally got my plane to another place to get my .411 and 413 pitot
static / transponder check, and it went from bad to worse.....

First person inspecting said everything was fine except for the VSI not
being hooked into the static system.

I take it to the new place (where I had it done 2 years ago) and they said
my transponder altitude encoder was off, and could not be adjusted, either
needs an overhaul or replacement, altimeter needs adjustment and overhaul.

I am just amazed at the wide differences of opinions.

My choices were, overhaul what I have, replace with an overhauled unit or
a
brand new transponder. This is in order of expense with the first being
the lowest expense.

After talking with a couple of people, I decided to go with overhaul what
I
got, as replacing it with another overhauled unit may be buying somebody
else's problem. For the Altimeter, I kinda expected it, since it was
about
40 feet off when I compared field elevation to the altimeter setting, so
no
surprises with that.

Transponder and Altimeter sent to Wichita for the overhaul, hope to be
back
in the air early next week. Total cost, probably $1000.00 after all is
said and done.
