[VHFcontesting] inverters

Mon Apr 14 19:35:54 EDT 2008

Hi Bill, OK I was a little confused.. You said the only issue with the inverter was that you had to keep the engine running, but it really has nothing to do with the inverter, only the amount of current drawn from the battery..

It does look like a nice unit though...
