[VHFcontesting] Roving: Battery vs Generator

We have been running a 2800w Onan Camper/RV generator.  With the 
installation kit it can be run off of the vehicle gas tank (down to 1/4 
tank for safety) and electric remote started from either the vehicle 
battery or any auxiliary battery.  It is small and compact and could be 
mounted externally on your van.  It is RF quiet and very reasonable for 
audible noise (not quite as quiet as the Honda EU1000).  We run the 
transceivers and accessories on the West Mountain PWRGATE with quiet 
switching supplies on one side and smaller batteries on the other side 
for backup and under way.  The big amps are all running on an astron 70A 
supply.  I have an idea for battery substitution on the Astron by 
placing 18V of battery on the input to the regulator. This is a work in 
progress and not yet built and tested.

Life really got simpler when we went over to the Generator with one 
exception ---  When the Air Conditioner on the RV is running , and you 
try to run one of the 400w anps plus a second transceiver all at the 
same time, the generator moans, groans, and protests! 

Good luck and 73,
