Hello All,
Anyone has any idea why we only have 4 channels for a simple walkie talkie? The engineering and physics reason for this 4 channels?
Kindly enlighten.
Thank you,
Jason
[TELECOM Digest Editor's Note: Jason, please begin by defining for me your use of the term 'walkie talkie'. Do you refer to a Citizen's Band walkie talkie? In the USA, those have 40 channels, _not_ 4 channels. But maybe you were speaking of some different kind of instrument. PAT]
