I understand what you're saying! I am not IFR rated and won't even
get into the IFR rules for TSO etc. since I don't know. I guess if you
have the desire to know for sure, you might call your local FSDO and ask
them. That should eliminate a lot of the guesswork. If they won't
approve it, it won't be flying...

I was really talking more about the installation rules for an IFR GPS. And
while there may be FCC rules about me building my transmitter I don't think
they would apply to me building a NAV receiver. I could be wrong but that
isn't the point. The FAA have created a set of rules for use of a GPS
receiver that are much more strict than those for a NAV radio that the
installation and use of is at least just as complex.

The only radio you can install that you built yourself (as far as I
know) is the RST series of Nav/Coms from Jim. Not sure he still sells
them. Not aware of anyone else offering kit radios. To use a radio
in an aircraft, it must be type certificated in the USA (I'm speaking
about USA rules...and does not necessarily apply to any other
countries)...

Your right in the US Jim and that is probably where the OP was
asking from but look at the address of "user." He is in the land
down under. Maybe they do have to be TSO'd there.


It would have to be, as there is no such thing as "IFR Category"
here (but there is on Oz).


Very true and sort of confusing when it comes to homebuilts. I can't
quite understand the reasoning behinde the fact that "I" can install
any NAV/COM in my plane including one I built myself if I so desired
and shoot IFR approches in IMC but can't use a brand new 430W that
"I" install to shoot GPS IFR approches but can use the same 430W to
shoot ILS approches.
