Much will depend on the Brand and Model of the repeater you are converting. International Crystal Manufacturing in Oklahoma City, Oklahoma, USA http://www.icmfg.com/ may be able to help. Important first step - be sure the repeater is working properly BEFORE you make any changes. Best 73, Steve

Dear Friends, My club, ANTRAK (Radio Amateur's Club of Ankara), is converting the frequencies of the out of band VHF repeaters (5 Ea)to Ham Band (144-146 MHz) to be able to use them for amateur service. 1- We are looking for the sources of the crystals needed and kindly ask the group where to order from stock ; or, for cutting to exact frequencies. 2- What are the parameters needed to order the crystals. The freq. of the repeaters are in between ; Rx 145.000 to 145.175 ,IF is 21.4 MHz (25 KHz step 8 of them needed) Tx 145.600 to 145.775 , (25 KHz step 8 of them needed) For the original crystalls ; Rx crystalls Fc= (f-21.4)/2 Fx crystalls Fc= f/9
