    They used the so-called crystal-saver design. The crystal frequency is multiplied by 4 to provide the local oscillator for a receiver with a 4.3 MHz I.F. In transmit the DC output of the receiver s FM discriminator is used to frequency lock the TX oscillator to the crystal controlled RX frequency. e.g.(8000 x 4) 4300 = 36 300 KHz.
