The average person who gets a Baofeng radio will have no idea how to tune in when they turn it on and see an input like 445.000 staring back at them. Pushing the buttons to blindly tune the frequencies up or down doesn’t work like a CB radio, car stereo, or marine radio. You can’t just pick a frequency at random and start using it. First, there will probably be no one to talk to. Second, you could be transmitting on a frequency or in a mode that is prohibited.
My pre-ham radio experience was with VHF law enforcement radios; my agency had 16 channels programmed in on the main ‘A’ bank. For public safety/business use, the FCC assigns frequencies. Not in the ham world. Ham radio does not have defined voice channels like Marine radio, CB, or GMRS/FRS. The concept of saying “Go to channel __” doesn’t exist.
What exists on the ham bands are portions of the frequency spectrum that is generally understood to be used for simplex (radio-to-radio) voice communication. Imagine it as a freeway without any marked lanes. To better navigate that lane-less freeway, radio users have decided to separate portions of each band and dedicate them to specific uses.
Simplex, or radio-to-radio voice, is just a small part of that. In order for the various uses of the ham bands to all get along, local radio coordinators outline what ranges and frequencies should be used for what. These coordinators are unofficial bodies and the plans aren’t legally mandatory, but they are mostly obeyed to avoid chaos, the same way people obey traffic signals when a cop isn’t around.
You can create “lanes” for your own channel plan as long as you play by the rules that everyone else does. This is really no more than agreeing on specific frequencies to use and giving them a name or alpha-numeric designation. Having a channel name or number is for brevity and communication security. “Go to five,” is shorter and more secure than saying “Go to 158.730.” So, within your own group/family, you can know that “VHF channel 1” means 146.415 MHz. Again, this is an in-group thing because there are no public ham channel allocations.Continue reading“Making a Simplex Voice Channel Plan, by Don Shift”
