Just another thought the stated tx draw is 1.8amps this is i presume
for 5 watts out if in this case ur using batt pack (stated 2watts
out) the draw will be about 8-900ma giving an even longer time
between portable charges !! if so its better than i thought
Incidentally I suggested to Mr Sam Ruddy @ Yaesu uk about 6 months
ago for them to manufactur a 10w version of FT100 with the
probability of an add on linear as the FT290r mkII so as to do away
with the bulk, the fan and 100w stages which would make a very small
qrp ideal rig he said there is no market for this ....... low and
behold the FT817 is imminent. Strange that isnt it.
