Good idea but don't forget that all the new Icom handhelds are illegal to use in Europe.
I think some misunderstanding/misinformation. Some years ago many microlights were fitted with ICOM A3/A22 as installed COM radios, and they were CAA approved. Once EASA took over Europe-wide avionics approval, there was no EASA specification for hand-held transceivers, hence no new handhelds could be approved. ICOM changed to the A6/A24 range, and there was no approval for use either hand-held or installed, for a variety of reasons; not least because they were not manufactured in Europe. For the same reason, their A210 replacement for the A200 panel mount fell by the wayside.
Eventually the upgraded 8.33KHz capable versions of the A6E & A24E
have been approved for use as hand-held radios in EASAland, although not installed (as EASA certification regulation doesn't permit that). Yet another example of EASA working for our safety - you know it makes sense. So now if you want to carry a handheld for emergency use, they are perfectly legal (so long as you hold an FRTOL) .
Meanwhile, the Yaesu TA310 8.33KHz handheld does all the same things, is more rugged and significantly cheaper. It also seems to work well with all headsets, and the battery life is better. It's what I use, but please yourself.
