Refer to sub section "Crystals, Oscillators & Piezo" under "Radio Systems, Accessories, Alterations and FAQ" on my web page for details of several manufacturers. More importantly, reasons why you must use the crystal sold or recommended by the manufacturer, of each Transmitter or Receiver, in that particular unit. Other brand crystals may appear to work in some other equipment but will not provide optimum performance and frequently cause problems to user or others.
