On a different message board someone was looking for a handheld VHF that was USB rechargeable and had the channel 70 (2187.5 kHz) DSC (digital selective-calling) distress feature. A few new handheld radios have DSC, which can send your coordinates to nearby receiving radios. Icom claims their M93D and M94D radios can acquire a GPS position in an impressive 8-12 seconds after being turned on. The M94D even adds AIS (receive only) which is pretty wild. I was not familiar with that system and he was not getting much feedback, so I thought I could cross-post the question here. Anybody have a radio like this and have thoughts on their utility? I assume there simply is no DSC unit on the market currently that does USB charging, and others have suggested he just convert a 5v USB to the 12v that the current radios require.
