Lee, that is very useful and interesting data. How about the ARGO V? I
was disappointed to see that it requires such a large power supply - I
assume for the 20 Watt output, but it seems to want "juice."

John and group,
A few years ago I tested about a dozen rigs for use on battery, both CW
and SSB where both
modes were available. CW and SSB were close to the same power consumption
with CW
being slightly better. Note: all rigs were full QSK on CW. The tests
were run at 40 meters
and 50% transmit duty cycle. (That's very heavy transmit use! Maybe net
control type use.)
The following results were calculated for 5 Watts CW using a 7.5 A/H batt
discharged 90%.
OHR 100A 0.75A 31 hrs
Argosy 1.30A 12 hrs.
Argosy II 2.70A 7.8 hrs
(disp off)
Argosy II 2.90A 6.4 hrs
(disp on)
Omni IV 5.9A 2.9 hrs
Just tossed the O VI in for fun. :-)
In each case the test sample was one unit.
73,

I have an Argosy and think it would fun to use it as a portable rig.
Has anybody built up a portable supply for it? The listed specs say
it draws .5 A on RX and 9 A. Max. Is it really 2 A. total at low
power ( 5 W)? as an extrapolation ? The FT-817 runs about 2A on
transmit aso I would think I would be in that range. At least one
person is using a 5000 mah battery as a supply for the 817. Just
thinking out load.
