Good points, John.  The comment about limited battery life applies for sure if you use NiCad
batteries.  My VHF's are equipped with alkalines, and I typically get many days of 4-6 hours of
monitoring, with some transmitting, before the batteries indicate they need to be retired.  (I use
the Duracell units which have a "PowerCheck" strip which allows you to check them.)  I've gone on
several extended trips (1 - 2 weeks on the water) with the alkaline backs, and find I can expect at
least 4-5 days of use before I begin to get concerned about reserve power if I have to transmit.

I no longer trust NiCads in VHF radios.
