Thanks Doug. I ordered the 90BAv3. I have an old PRC-90 and while it came with a functional battery on receive, I have no way of knowing how long it would last if I needed to transmit.

PRC90 is a pretty good basic emergency radio.

It transmits both voice and morse on 243.0 MHz (Int'l air distress & guard on every military UHF radio I've used) and also voice on 282.8 MHz (Joint/combined on-the-scene voice) aka SAR common. That combined with a PLB should provide pretty good comms; bring the outside world into range and then talk to it.

Just another hope-I-never-need-to-use-this piece of gear.
Better is the Enemy of Good Enough.
Okay, what’s your point??
