The Run Announcement will indicate which type of Radio (Ham or CB, not both) will be Required. Each vehicle MUST have the type of radio specified. Few leaders now specify CB, the majority require participants to have a 2 meter Ham radio.
We strongly recommend the Baofeng UV-5 available on eBay or Amazon for less than $30. including FREE Delivery. A license is not Required to buy the Radio. We do not require participants to have a license but do recommend getting one. One good way to get your license is to take the Free, One Day License Class . Many find that this is the fastest and easiest way to get the license.
