Hello All, I have a 1974 Bearcat 3 scanner that uses crystals. It has an I.F. of 10.8, unlike almost everyone else who used 10.7 I need the NWS frequency of 162.475 MHZ. If you have such a crystal that uses the I.F. of 10.8, please contact me direct. Thank you very much. Duane Fischer, W8DBF dfischer at usol.com
