[Boatanchors] BMW Mini Automobile Radio Installation query

[Bill Cromwell]

Hi,

I know some hams who carry an independent battery like a marine deep 
cycle battery to power the mobile radio. They recharge the battery 
separate from the car. If you are going to be on a transcontinental 
motor trip and you talk a lot it will be better to connect right AT the 
car battery. You may have to install an in-line noise filter with the 
car battery. Don't bother with that if it works okay without one. If you 
hear your instruments, ignition, fuel pump, windshield wipers, etc 
install a filter that can handle your 7 Amps on transmit.

73,
