frequency question

[itzdan]

Two questions which I'm sure are easy to answer -

1. What does it mean when a frequency has an R next to it? And when programming it into my scanner with win96, does the R have to be programmed in somehow?

2. What is the difference between frequency and input? Which one should I program into my scanner? And what is meant when it says simplex?

Thanks!

The "R" means repeater. That would be the one you'd want to program in your scanner since it's the output side of the repeater and you can usually hear both sides of the transmission. You don't have to add the "R" when putting the frequency in your scanner, just the numbers.

A repeater has two frequencies, an input frequency that is used to transmit to the repeater, and an output frequency that's used to...well, repeat the input traffic along with the dispatcher's traffic. In the vast majority of cases, you only need the output channel in your scanner.

Simplex means the system doesn't use a repeater and the range is dependent on line of sight. With a repeater system, you may be be able to hear mobile units from many miles away. With a simplex system, you will only hear the mobile units if they are in you antenna's line of sight. This is usually two or so miles for the standard rubber duck up to maybe 10 miles with a good roof antenna. These numbers vary a lot depending on the terrain between you and the transmission you're trying to receive and the frequency band being used.

Thank you so much Jim, very helpful!

If you just want to keep it simple with a repeater system, just listen to the output.
