Where do you get 30 amps from to run a radio on a bike?

Not that I've seen a lot of two wheel cell phone users (blue tooth is
hard to spot), but how many people have seen two wheelers on a CB or
Ham Radio while driving?

I know lots of people with intercom headsets, but no hard wired CB
users. Does the headset keep wind noise out? I just saw an ad for a
ham radio that uses blue tooth...again, how do they keep the noise
from broadcasting over the radio when they talk?

With some of those rigs drawing 30 amps, where do they get the power
on a motorcycle?

 

It's a very power-hungry ham rig that draws 30A- an average number is a bit
below 20A peak on transmit (maybe 10% of the time), and 2A/3A
on receive (about half your headlight draw).

And a legal CB or a low-powered ham rig only takes 2 or 3 amps peak on
transmit.

It's not actually too hard to run a second battery for the radio, too.
I have all the bits, just need the time and energy.

A good windshield and/or helmet helps with the noise, also
noise-cancelling directional microphones.
