Curious to know... did you make this a field approval? So a fed
stamped box
3 on the 337? If not, what approved data did u use?

Around here, A&Ps are limited to installing ELTs. A real pain. I
have to get a shop to run all this thru... then they have little
problem.
A&Ps have no standing, even IAs.

I'm curious whether it's really different where you are.

I did a 320A slide-in replacement for an old Narco AT-50.
I replaced both the antenna and the coax, primarily because they were
of unknown age. The installation was painless and I filed a 337 and had a
transponder cert done to complete the process.

Did you file the 337 yourself or did you have a shop do it?

I'm an A&P/IA. I did it myself.
