<br><font size=2 face="sans-serif">Tony S can give you the tech detail, but receivers are tuned circuits. The crystal is key to creating the reference frequency used to filter the signal picked up on the antenna. The crystal sets up the basic reference frequency and the circuitry around it can only be used for a narrow range, or band, of frequencies. The futaba receivers come in two types that have components that tune each to a different band. You can put a low freq crystal in a high band receiver, but you'll have a detuned system, reduced range, and possible signal lock loss. I wouldn't do it.</font>

<br><font size=2><tt>What's the deal with high band and low band for futaba crystals? I'm<br>
having interference problems on channel 44 at our field, and a friend<br>
offered me an extra channel 35 transmitter module and one rx crystal.<br>
Can I switch over without harm? According to Tower's website 44 is<br>
considered high band and 35 low band.<br>
