Yesterday my ICOM vhf (which has DSC capability) would suddenly change to
channel 16 and emit a very loud ambulance siren type sound from the speaker.
The volume of the sound was not controllable and be canceled by changeing
channels or pushing the DSC button.This happened quite a few times. Today I
tested the unit by leaving it on for a good while , checks OK. So could this
be caused by solar flares?

Interesting, I noticed my digital cable (t.v.) loosing signal some
yesterday. Doesn't usually do that, so who knows?!!
