no, its a normal 23 channel radio.
the reason the crystals are in the 37.### range is because the crystal's freq. is mixed with another crystal's freq. (most likely around 10mhz) to make the required 27.### freq.
different manufacturers used all kinds of different mixing combinations. 23mhz, 11mhz, 17mhz, all kinds.
look in the radio and see if you can find one or two crystals that are in the 10mhz range.
