Which would be better for emergency situations: VHF and NOAA or shortwave? i ask because Eton makes the FR350 and FR400 which are both the same except the FR350 has short wave along with FM/AM, but doesnt have the NOAA channels or VHF (TV), however the FR400 (seen above) has NOAA and VHF along with AM/FM but no shortwave frequencies. i am curious because i want to get one or the other and i am not sure which would be more useful.
