I would like to buy my first set of walkie talkie and I am confused about the use of channels. I know I am asking a lot of questions but I will be happy with any help. Thanks in advance.
From what I read, these devices operate in the UHF spectrum. Each different channel corresponds to a different frequency band (centered about a specific frequency). For two or more users to communicate, their walkie talkie must be on the same channel.
a) Other people with walkie talkies set on the same channel and in the proximity can be part of the conversation can eavesdrop or participate even if uninvited, correct?
b) There are usually 22 channels to choose from. Which channel should we pick? The one over which the communication is most clear? I am also not clear on the overlapping of channels and FRS/GMRS. Are FRS and GMRS different modalities (standards) to communicate? Should we choose FRS or GMRS channels? What about those channels that are both FRS and GMRS?
c) Should the channel be agreed ahead of time with the other users?
d) The privacy codes perform filtering letting the users hear only those users with the same privacy codes. But anybody else can still here the conversation if tune on the same channel (just not as crisp)…
e) Can a single frequency carry multiple channels? Or does it channel has one specific frequency?
