[[/I] I have searched for freqs of headsets at KRYSTAL company owned fast food restaurants......found sevsral fast food list for Krystal....anyone have any ideas?

I have made a list of fastfood frequency pairs in southern florida and upstate ny. I don't have my list readily available but I can get you the exact frequency pairs at a later time. I do know that on lowband the following frequencies are popular:30.840, 33.160, 33.400, 35.020. On VHF Hi-band you can search 151.000 to 152.000 and 154.500 to 154.625. On UHF search 457.000 to 458.000 and also 464.000 to 465.000 and 469.000 to 470.000. And finally search 902.000 to 904.000 and 920.000 to 922.000.
As far as pairings go the low band frequencies are the customer freqeuncies & are paired to the VHF Hi-Band frequencies which are the clerk frequencies. For UHF the 457 mhz frequencies are the customer frequencies and are paired with the 464 mhz frequencies which are the clerk frequencies. The 469 mhz frequencies are the customer frequencies and are paired exactly 5 mhz below on 464 mhz which are the clerk frequencies. And finally the 920-922 mhz frequencies are the customer frequencies and the 902-904 mhz frequencies are the clerk frequencies.
Most fast-food restaurants have a continuous carrier on there customer frequency which makes them easy to find. Other's only transmit when someone pulls up to the drive-thru. They just about all use PL Tones as well. I will get you the pairings by later on this evening. Any further questions please don't hesitate to ask!!!!!
