Remi, Yes it is a complex issue and a pretty expensive one
too. I have been persuaded though that the intercom
facility on the Garmin GNC 255 or GTR 225 is good and I do
plan to scrap my Flightcom intercom. With a 255 costing
the wrong side of 3000 I have on the other hand been
seriously tempted to buy the simplest small 8.33Khz radio
at around 1000 and fit that in addition to my SL30. There
is also the question for us oldies of pilot 'Sell by
Dates'. I ask myself whether I shall still be flying in
2017! My heart says Yes, Of course, but the head might
come up with a different answer!
Regards, David Joyce, G-XSDJ (just received my first free
TV licence)
