Dear Brett,

I made a modification to KBT1 option just to have more power and better
audio response.
I use 6 Lipo cells 2 x (3 x 3,7V/900mA). Voltage range is between 4,2V
(fully charged) and 3,2V (discharged).
My inspiration was an interesting article of WA3WSJ (KX1 battery
modification).
There are some notes on my qrz.com page but, however, it'll be difficult to
have 4 hours at full power using normal contest operations. Instead you'll
find it perfect for casual operations.
