IndyCarFreq

The Sql Tone listed in the table below can help reduce extra transmissions on the scanner. But, if the tone is wrong, can also prevent you from ever hearing your driver. If you don’t know how to turn this feature off on your scanner, and don’t want to learn- get the no-tone version. This will ensure you hear everything on the frequency. Or- follow this quick tutorial on the right about how to change/remove tones while at the track in case the config file is wrong.

If you are using the Bearcat BC125AT and you find that you can't hear a driver, it could be one of two things.

First, check the secondary frequency for the driver. They might have had to switch to their secondary frequency for some reason. 

If you don't hear them on that frequency either, you might have a tone-squelch problem.

Tone-squelch is designed to help keep out all transmissions that don't include a particular additional "unbearable" tone or digital signal. This prevents little kids on walkie talkies, drive-thru speakers, and other random things from causing static or other noise from being a distraction to you or the race car drivers. It's a great feature. But if it has been programmed incorrectly, miscopied by me, or if the team had to change it after you programed your scanner, you will only have silence on that frequency. Here are two ways to fix it.

1- remove the squelch, and hear everything again:

• Go to the channel that isn’t working
• Press Func and then Pgm/E
• Scroll down to Set CTCSS/DCS, and press Pgm/E
• Scroll up to Off and press Pgm/E
• Scroll down to Exit and press Pgm/E
• and now it’s turned off, and you’ll hear everything on that frequency!

2- put the scanner in search mode, note the found tone, and reprogram it. note- this will temporarily open it up, as above, but lead you to locking it back down again. 

• Go to the channel that isn’t working
• Press Func and then Pgm/E
• Scroll down to Set CTCSS/DCS and press Pgm/E
• Scroll down to CTCSS/DCS Search and press Pgm/E
• Scroll down to Exit and press Pgm/E
• Listen and watch your display. When there is a transmission between the driver and pit, you will see the Tone information flash below the frequency number on the display of the scanner. Remember this information or write it down. Also, note if the number has a decimal in it or not.
• Now press Func and then Pgm/E
• Scroll down to Set CTCSS/DCS and press Pgm/E
• If the number that was flashing had a decimal in it, select CTCSS, if it did not have a decimal in it, select DCS, and press Pgm/E
• Scroll through the list of all those numbers until you find the one that was flashing and press Pgm/E
• Scroll down to Exit, and press Pgm/E
• You have now reprogrammed the Tone for that channel to the correct one for your driver.
