That's interesting. Do you know if the 5000A has the same
characteristics? I was thinking of running mobile in my 24' I/O boat
this summer for a couple of nights. I'd like to be able to use the 5000
without having to run the engine all the time.
As long as I'm asking the questions, I was going to pick up one of those
Hi-Q antennas for the boat. Does anyone have any good suggestions for a
ground plane on a small (24') fiberglass boat?
Thanks.

All Flex-3000 users:
The dropout voltage of the 5V regulator is 2.5V, all the lower voltage
regulators are LDO types.
I have completed a few simple low voltage tests, the production
calibration
tests all pass at ~11.4V.
The preamp is the only non-regulated voltage active component in the
receive
path and has .3 dB less gain at this reduced voltage.
Tested the transmitter on 20mtr USB with a recorded wavefile: Info panel
reads ~10.7 V, Powermaster wattmeter: 83W (Tune @100 drive level) and
listened on a F5K audio sounded same as full voltage of 13.8V.
The Flex-3000 was used mobile traveling from Austin, Tx to the Dayton,
Oh
Convention, and return trip operating as K5FRS, with no technical
problems,
although band conditions were not the best.
