Then,set the BAND switches and main tuningdialonthe receiver for the riominal transmitting frequencyofa desiredpartner stationwiththeRIT switch placed in positi

4、on O.Tunethe receivertothe actual transmitting frequencyofthepartnerstation and proceed totheQSO operation. Ifthe receiving frequency shifts during the QSOoperation, re-tune the receiver to the currentreceiving frequency by turning theRIT controltoandfro, insteadofmanipulating the main tuning dial.O

This control should be adjusted until thereceiver provides the maximum sensitivity. (6) SQUELCH (Squelc
