Thanks, Eric. Very helpful.
It appears from the information on that site that the FCC certification for the M802 was issued in July 2002, and that it was for maritime use only.
I seem to recall
that this radio
was at some earlier point marketed with the flexibility to do both ham and marine
actually touted. I've seen many references
to this, including in the reviews
section of QRZ.com. And, there can be little doubt that the design of this transceiver lends itself to much wider use than maritime only.
Maybe the designers and marketing
folks got out ahead of the regulators? Or, for whatever reason Icom
decided not to seek approval for multi-service use?
