Subject: AeroElectric-List: UPSAT Transponder


My UPSAT transponder Apollo Model SL70 gives Air Traffic Control the  
accurate altitude compared to my steam gauge altimeter and Chelton/Grand Rapids

Technology units.  However, the INDICATION on the face of the transponder  
is 300 feet off.  Therefore not a problem with IFR, i.e., ATC gets the  right 
altitude from interrogating the transponder  (I've asked ATC  numerous 
times), but I'd like the readout on the front of the SL70 to agree  with my 
other altimeters.

Any easy do-it-myself fix?

Don

To do that, you'd have to set the altimeter setting on the
transponder somehow so that it was reading whatever the
altitude of the day for that pressure is.  This is just
how they work, if I'm understanding your dilemma correctly.
The transponder isn't an altimeter...it just gives PAlt
to the other systems.  So don't think of it as such.

Thank you Joe & Bob,
I currently have Z 19 installed. I kind of like your Dwg.
Maybe next year I may change it around. Right now, all I want to do is get it running
and fly off 5 hrs.  
It's been a very long summer for engine change.
One damn thing after the other. Oh well, it will all work out in the end.
Thank you again for the help.
