As I've written on my rover web page, my IC-706 MKII (Hell, everybody's
IC-706) transmits like a squished rat when the supply voltage drops
below something like 12.5999 VDC. All my previous rovering involved
driving to a grid site - parking - and contesting for 10-15 minutes with
the engine off before someone would remark that my signal was distorted.
Then, I had to start the engine at high idle and suffer the increased
noise floor.  I added the original N8XJK Boost Regulator in 2007 and
have been quite pleased ever since.
