[Elecraft] OT. what power for K3 in portable use?

[Don Wilhelm]

Manolo,

Choose the largest 12 to 14 volt battery that you are willing to carry 
along - if the sun is shining, you may want to extend the operating time 
by adding a solar panel to the battery to keep the charge level up.

The K3 draws about 900 ma. on receive, and the current will be more when 
transmitting - the transmit current depends on the power level you have 
set.  You can calculate your operating time on any battery by referring 
to the Amp/Hour rating of the battery - you will likely be able to use 
it for about 1/3 of the AH rating - when the battery drops to about 11 
volts, you should stop using it until re-charged.  Keep the power 
setting low to extend your operating time.  Have fun!

73,
