All of the radios PCI offers do have scan functionality. However, we do not add in the scan feature in the standard programming. If you turned scan on all channels, your radio would likely be stuck on the PCI Weatherman channel the entire time because of all the chatter during the race. If using for recreation, it's not impossible some of these frequencies could be tied up by other businesses or users (or even data) and with 128+ frequencies programmed into some radio you likely wouldn't stay on the frequency you wanted for long. Some users are advanced enough to understand this and be able to select scan, but we found this caused more problems than solutions and have opted not to add it to our programming. If you have a different use case and think this feature would be a good addition for your team/adventure - we are happy to add in that functionality. This programming does need to be done at HQ, click here to send in your radio for service.
