A "Gas Gauge" for the Yaesu FT-60


Back to what I was looking for in the first place...

When you first switch on an FT-60, it displays its battery voltage briefly.  A quick conversion from this value to (for the stock battery) some percentage of remaining juice would be helpful!  And here it is, lifted from the document http://www.hamoperator.com/Fusion/FusionFiles/K9EQ-Fusion-PDF-0002.0.0_FT1DR_Power_and%20Battery_Performance.pdf


And there we are.  It's a pretty flat discharge curve, and no doubt things will vary with age and temperature, but it is good to know that setting off for the woods with the battery reading 7.0 V probably isn't the best move.

Why can't Yaesu put this in their manual?  No, it's not perfect, but it's better than "good, good, good, oh crap down to 3.6% remaining, now 1.2%,  dead" indication that the battery bar gives.
