Trying to get some basics right bc72xlt NASCAR scanner

[biffspagnuts]

Knowing very little about scanning basics I turn to you all for help. I bought the aforementioned scanner in the title from eBay. I was hoping to use it to pick up two channels. 152.39000 and 157.65000 from here
Businesses Scanner Frequencies and Radio Frequency Reference

https://www.uniden.com/scanner/id-BC75XLT/BC75XLT_300-Channel_Handheld_Scanner
I've skimmed over the manual above and get error when trying to save the above channels.

So first question is this scanner able to even pick up those frequencies?

I tried broadcasting (holding the mic down on a radio) on one of the unused channels while scanning and caught the broadcast on a totally different frequency # 45.000 something.

While scanning open channels the scanner seems to just skip the entire #range I want.

So can anyone help me understand what I am missing here? Do I just need to buy different scanner altogether to get the frequencies I want?

What steps are you following? It should work fine for those frequencies.

Ok thanks Paul, I went back over what I was doing and realized I was mixing up the term "channels" with "frequency" . I was entering a frequency number as a channel number... It was complete user error
