CB's DO NOT operate on AMATURE freqs. PERIOD NO DISCUSSION. They are in a separate segment of the spectrum. CB is a "legal" 4 watts. AM for the most part. short range and generally low quality. If shtf repeaters will not be an option. Mobile 2/70 range from 5 - 75 watts depending on model. HF rigs are generally 5 - 100 watts. even with that kind of power, your antenna can make or break your station. Ask any QRP Operator. If you want to bet your ass on a hand held, Get to be friends a with a guy who can service Motorolas, pick up some old HT-1000s and go at it. The RADIUS mobiles are also very reliable and Idiot proof.
Seems I got your jimmies rustled, I apologize for that.
It wasn't very clear and a little mixed up. CBs and Ham radios can communicate if the ham is simply tuned to a CB frequency. Is that better.
No, I didn't say it was legal.
