Heading to Hawaii this Christmas and thinking
of taking a Sony 2010 --
Any hassles or obvious tips I could use?

Thanks!

Other than don't turn it on during the flight.. should be no
problems. Best
to pack it in your checked luggage.

Some airlines DO (or, at least, did) allow the use of radio
receivers during flight. Virgin is one of them. It may be worth
asking. It's interesting to note that, when you travel from the UK
to Florida, the first language you are likely to hear on the FM B/C,
the USA, is French.
I don't know any airline that allows AM/FM radio use at any time.
The LO on many FM radios causes radiation in the Navigation band.
Trust me, a few years ago, Virgin definitely did allow the use of
radio receivers. It was on the list, along with PCs, calculators,
electronic games etc. Without a doubt, the top end of the FM B/C band
+ 10.7MHz does put the LO in the air traffic control band. However,
in practice, it's difficult enough to get even FM signals inside the
(you have to have a window seat). Even at ~100MHz, the windows are
still a bit on the small size. So, I doubt if a relatively weak LO at
120MHz is unlikely to have much impact on the ATC communications.
Those guys don't really go in for weak-signal communications.


It's not likely to prevent comms, but it can put a heterodyne on top
of comms. Which, in a cockpit, on approach in high traffic areas, can
be a major distraction.

Oh, I agree, it could put a heterodyne on top of comms (especially as
they are AM) - and possibly a very unstable one at that. But, as I said,
those guys don't really go in for weak-signal communications. Presumably
Virgin did an assessment of the risk, and decided it was negligible.
