Hi Remy
Am I missing something here? Why do you need to switch modes to work in the
25 spacing? Does not the 8.33 spacing simply provide 2 extra frequencies in
the gap between the exiting 25 spaced ones?

Pete

Subject: Europa-List: Re: Intercom Do you need one
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?
