From the ICOM website -- the IC-M710
a.. Covers all allowed bands between 1.6 and 27.5 MHz
a.. But propagation varies on each band depending on night or day, time of
year, time in the sunspot cycle, solar storms, ground wave propagation, etc.

Suggest you read about propagation.

I visited this website
http://www.icom.co.jp/world/products/marine/index.htm trying to find
out what is the distance that IC-M710 can communicate. I guess the
answer is it depends, can anyone tell me what is the typical distance I
can expect this unit capable of. The website tells me "A full 150 W
(PEP) of output power is available for reliable long distance
communication" but how long is long, really.

Thank you,
