[TenTec] Pegasus experiences 11-12V DC power in ?

[w4chl at amsat.org]

Anyone had experience with Pegasus operating 11-12V at low output power ? 
I'm testing, and it seems to work at these QRP levels, but I haven't been 
able to get a signal report from anyone, have to setup for PSK31 and try 
again. Reason for asking, hoping to run this Pegasus as part of class A 
battery station, and can't count on over 12V for very long in between 
solar charges from these 100A-hr marine batts.
