Hi Clark,
I'm a member of ARES and have been intrigued by the idea of going with a
deep cycle marine battery.
I tested "our" Corsair with a fully charged 7 amp hr gel cell and got a
report of a little "flutter" that went away when I switched to the Astron.
I hope to be on the air mobile from CT in the upcoming NEQP and I think I
will get a deep cycle battery and the booster just to be safe.
I'm wondering - did you do much ssb with the battery or mostly cw?
When I key the mic on battery I can see some frequency searching on the
readout. With a power supply, the readout will stay stable about half the
time and will be a little unstable the rest of the time on transmit. The
readout is stable on receive, and then fluctuates a bit when keyed. Is that
okay?
tnx,
Bob KB1CIW
P.S. is anyone wants to sell a used booster, contact me off list.

Just a thought (though you may already have had the same thoughts, it
is worth a moment!)
1. Check your power cables for voltage drop (improve them as a matter
of course)
2. Check your power connectors for voltage drop (use a bit of DeOxit
or something on them)
3. Measure the voltage somewhere inside the radio and also at the
power source to see exactly what the drop looks like, it could help you
find a simpler solution.
If I recall correctly, my Corsair (isn't this the one you have Bob?
:-) worked fine from a Marine Deep Cycle battery, even with the Herc II
attached (at full charge). There may be hope that the Corsair should
hang in to reasonable voltages. However, I've had a few Scouts around
and they are not so forgiving.
I believe the battery booster is a great idea regardless, but the
voltage drop is an easy problem to look for and cure in most cases!
