CB? Really? I put one right next to my cassette deck...between my Kraco head unit and Radio Shack Equalizer. :giggle:
Seriously. Hand-held two-way...the only way to go. 08H3 turned me on to using these, and I love em.
No static.
No squelch.
No Trucker chatter.
No wiring.
No antennae.
No expense. Read some reviews...range can vary quite a bit but, I've never had an issue with range for wheeling purposes. Cheapo Walmart 2-ways totally blow away my Cobra Roadtrip HH CB (an absolute total POS of a radio) but, I'll admit...my wife misses flirting with truckers to/from the off-road parks!
I specifically like small AA-battery powered units, and some of these work with mini-headsets (ear-buds) so you and your spotter can discuss a route without yelling at each other. The FCC frequency range is the same on all of these, regardless of brand...so multiple users can all tune-in to the same channel regardless of manufacturer. Prices range from $27 for the Hello Kitty model...
...to pro-quality for $346...
Also look into motorcycle 2-ways. These are small, voice-activated, two-way, head-sets...perfect for spotter-driver communication.
