I am using a Uniden Bearcat BC75XLT Scanner. I use it at local Stock Car Racing tracks. It easily locates most racing teams frequencies. It locates the Drivers One Way Radio frequencies. These are located in the 450 to 470 MHz range.
Out of the 4 local tracks that I attend, I am able to locate the frequencies for Race Control also in the 450 to 470 MHz range. However, at 2 other track my Scanner cannot locate Race Control. My question is why can’t the Scanner locate that frequency?
Is it that the Track has different radios that a Scanner cannot locate?
I found a web posting (from 10 years ago) that indicated that one of the tracks had a Race Control frequency at 154.4900-Dpl-031 and 149.4900 DPL tone 031.
I tuned in to both154.4900and 149.4900 and heard nothing. However, I do not know what is meant by -Dpl-031 DPL tone 031, because my User Manual does not explain those terms.
I would appreciate any info you can give me. I am a novice with Scanners and I have no knowledge of Two Way Radios.
Other than that, we have had great fun listening in at the track. It makes it so much more fun to know what going on.
