[Elecraft] Power Supply for K3 for Contest DXpeditions

[WILLIS COOKE]

Jose, I have a Jetstream JTPS28M Switching Power
Supply that I have been using for over 18 months with
two transceivers, including several 48 hour contests. 
It weighs 4 pounds, is compact, has two meters.  I
bought it from R&L Electronics for $99.95.  I am not a
DX station and probably do not contest as hard as some
DX stations, but it has held up nicely for me.  My
TS-850 and FT-900 draw about 3.5 amps on receive which
I am sure is more than your two K3s.  Key down on one
transceiver is about 21 amps which it handles nicely. 
It will not handle transmit on both transceivers at
one time.
