Do you have a photo of your headset kb2ztx. Your headset has two plugs for each twoway and one scanner jack?
4 dif nascar scanners I recommend and use
Top two "Re1000"
Rectangular box "ReSwitch"
Cellphone looking one "ReLEGEND" scanner. All only pickup 450-470mhz
Since this thread is basically entry level questions about nascar scanners, Then I guess I'm not to far off thread topic. So, I will mention few basic items.This one being scanner audio amp. This is needed to hear at alot of race tracks. Along with some headset with noise reduction.
