Para aumentar o granel, aqui vai uma coisa interesante que encontreo nas FAQs do geocaching.com:
"Do you have an FRS/PMR channel to find out if other Geocachers are in the area?
Yes. The community has decided on channel 2 as the primary for both FRS and PMR, and 12 as the alternate FRS (Family Radio Service) channel and 8 for the alternate PMR (Europe). FRS and PMR radios are longer distance walkie talkies, like the Motorola Talkabout."
Portanto, o canal principal é o 2 e o 8 é o secundário (para a Europa).
E agora, o que se decide?!
