Every channel of a two way radio operates on a specific frequency. In order to prevent one channel from spilling over and interfering with another channel, radios have traditionally been made with a 25 kHz frequency spread between channels. More recently modern manufacturing techniques have allowed radios to be built with a 12.5 kHz spread. The old 25 kHz spread is called wide band. The newer 12.5 spread is called narrow band.
Narrow banding allows for twice as many channels without interference. Starting in about a year the FCC has mandated that radios will not be allowed to operate on wide band.
Most radios that have been built in the past 15 years have the ability to be programmed in either wide or narrow banding.
A customer sent us a radio this week. The customer is a school out in California. They are buying new radios from us but want their existing radios to work with their new radios. So they sent us one of their existing radios so we could copy the frequencies.
Once we scanned their frequencies we discovered they are using wide band. Their old radio has the capability for narrow banding but the change must be programmed into the radio.
As part of our service we asked the customer to send all their radios to us for reprogramming to narrow banding. It’s a school so they immediately asked, “How much is this going to cost?”
“It is free!” we told them. “We do not charge our customers for programming or re-programming.”
Yippee! Free radio programming. Another reason to do business with 2 Way Radio Express. Doing business with us is easy.
