um... Wasilla...
Good info, but the link in the release doesn't work. I guess I'll have to do a little investigating to see if my radio has auto switching.

Press release in April 2010 copied from the PDF Posted above. Just like Gov to not say what Mfg they found the problem on, but I think this would be the very high end commercial units. But i'm guessing

It has come to the Coast Guard’s attention that an​
automatic channel switching feature found on
certain models of Digital Selective Calling (DSC) equipped VHF marine radios may create an
unintended hazard by automatically switching from a working channel that might be in use at the time
to Channel 16 when the VHF marine radio receives a DSC distress alert, distress alert
acknowledgment or other DSC call where a VHF channel number has been designated. This could
happen without a vessel/radio operator’s immediate knowledge and could initiate an unsafe condition
by which the vessel/radio operators would believe they were communicating on a working channel
such as Channel 13 when, in fact, they were actually on Channel 16. Imagine a towboat operator on
the lower Mississippi River making passing agreements on VHF channel 67 and then suddenly,
without warning, not being able to quickly reestablish communications with those vessels because

his/her radio automatically switched to Channel 16 instead.
