For some reason, I'm having a problem in the "reliable" department right now, and it's a good lesson/reminder for all you folks interested in Emergency Comms.
I acquired 3 brand-new and name-brand FM transceivers in the last year to use specifically for emergency SHTF communications. They have been used very little, and the batteries have been judiciously and sensibly kept charged. 99% of the time, they sit handily on a table in my den turned off and ready to be grabbed at a moment's notice.
First one of them, and then another of a different manufacture, failed to receive at all. They transmit fine, but won't receive anything. Within a few days of their inexplicably crapping out, they had both been checked and found to be functioning perfectly.
So, a reminder of a couple lessons:
1. Two is one, and one is none.
2. And just because it's working perfectly today, doesn't mean it will work worth poo tomorrow.
