[TenTec] boost mobile voltage?

[Bob Stephens]

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.
