Hi Remi and list members,
I am also thinking about the best way to organize the transition from the 25
to the 8.33 kHz mode. I have a Garmin SL30 in my panel. The GRT225/GNC255
doesn't fit in the SL30 slot, thus a panel rebuild would be necessary, what
I really don't like. Have you considered adding an ICOM IC A6FR II to the
existing equipment? It is approved by the DGAC and has a JAA-FORM-ONE. I
think I will install it in my Europa in addition to the SL30 to get both,
the 8.33 mode and radio redundancy. A feasible solution?

--> <air.guerner@orange.fr>
Hi David,
I am late on that one but I would like to add some comments. I am using a
separate intercom (Flightcom 403) as my radio does not have a built in one .
Now I am thinking at the possible architecture of my future 8.33
installation. It is very tempting to withdraw the intercom, therefore saving
panel space and making the wiring simpler, but I see one big drawback:
controlling the intercom function would be a lot more complicated. I have
reviewed the Pilot Guide and the Install Manual of the Garmin GTR 225 and
GNC 255 radios. There is no dedicated controls for the intercom function on
those units.
With a separate intercom, when you need to adjust the volume or the squelch
of the intercom, you just rotate a dedicated knob, which is intuitive and
very quick. With the GTR225/GNC255 you have to scroll through several pages
of menu , using several multifunction buttons and knobs with a risk of
making a mistake. In fact this is a configuration task, better not do be
done in flight.
BTW switching from the 25 to the 8.33 kHz modes with those new Garmin radios
is also a configuration task, so I am afraid it will not be easy to handle
the transition period, which may last for several years, where both modes
will be used by ATC. May be keeping our old radio for use in the 25kHz mode
and use the new one for the 8.33 mode only?
