[VHFcontesting] Roving120 VAC

[russell beech]

 I use a pair of 120 VAC rotors and a 120 VAC Laptop charger.  I have used purpose built inverters rated up to 300W but not found them very effective.  I now use a UPS that has 'black start' capability IE I am able to tell it to provide 120V 60 Hz without first connecting to the mains.
It makes some noise but it not the largest contributor to the mobile noise floor.  I estimate that too be the cell chargers, a laptop second screen and the laptop itself.
The noise is also most noticeable while rotating the array.  Some thing that is done often but is not continuous.
