For the Garmin folks, will there be the capability to update the GTX 327 firmware at Oshkosh, I have an older unit for my Champ that I need updated to the latest firmware (2.12 if I recall correctly)
Thanks

Hi Figs,
We'll be able to run transponder software updates for EAB aircraft at the show this year.

There is indeed a cap in the output oscillator to adj frequency (C525), it has to be disassembled and run on the bench with appropriate test equipment.What is used to bring them back into spec? Is there some tuning pot on the board you turn while looking at the output on some measuring device? Looking at the maint manual https://www.experimentalaircraft.info/doc/garmin/GTX327-M-Guide.pdf it doesn't look like there are any tunables, just tests that lead to board replacement. I hope mine lasts a long time, I'm not at all interested in a 1090ES transponder. I like the GTX-327/GDL-82 combo which shows up as VFR on the fish finder.

They really do drift out of spec quite often. I charge an hour bench time to do it so generally not a big deal.
Walt,
When would you suggest to have it checked? My unit is getting old, but the IFR check comes back fine.
