Please note that single conversion receiver crystals will not match in the frequency number to dual conversion transmitter crystal. For example when you order from HeliHobby a channel 18 crystal for your single conversion GWS receiver, the frequency printed on the crystal will not match the one printed on your transmitter’s dual conversion crystal. The following chart is meant to simply things by creating a channel mapping table; this way you can only worry about crystal channel number and NOT frequency.
The table below lists the frequency and corresponding channel numbers for single and dual conversion using both the positive and negative shifts.
