roups.com... Which HF radio xcvr was used in theSBDca. 1940-42? My feeling is
that it would have been the ARB, but need to have this confirmed. This
is for a scene in a movie set in Guadalcanal in 1942, where a link to
home is maintained by (quote) 'a radio scavenged from a wreckedSBD'.
A serious authenticity effort is being made.

Thanks,

Lamont,

Thanks for that really interesting and informative response - much
appreciated. A 12VSBD! The idea of trying to start an R1820 on 12V
doesn't really appeal, esp. on a frosty morning.

The choice has been narrowed down to ARB or GU, both of which are
available. My feeling is that the aircraft used in combat would be the
later models, which could well have used the ARB.

Thanks againm

Major brain fade! The 12V R1820 would have used an *inertia* starter,
not a direct-cranking starter.
