Not a 430, but a 530/kx155 combo. No differences noted in transmission or
reception one to the other

Hi folks,

As a followup msg, I wrote awhile ago about the poor reception performance
we were getting after out GNS 430 was installed. As a reminder, TX for COM
was fine, GPS was fine and NAV was fine. It was just the RX of the COM.
The RX was working about 25% as well as the KX-155 as measured by range of
reception at altitude, 4000' or so. The GNS was really limited to TERM
operations only, meaning within 10 miles or so.

Well after the avionics shop replaced just about everything else, it
turned out that most of the issue was resolved after replacing the
antenna. Now the COM function of the GNS works reasonably well, but still
not quite as well as the KX-155 we also have in the plane.

So two parts to this msg, 1, thanks for all your help and suggestions. To
those of you who voted antenna, you win. The second part is for folks that
have the GNS 430/KX-155 gear, what are your experiences in terms of what
COM radio works better?

thanks again for all your help.
