Turn manual control to allow the planetary arm to run against the feeler gauge. *Before making this adjustment, check the setting of oscillator core “H.” The rear of the core should be 13S from the mounting end of the coil form. This measurement is readi

With the radio installed and the antenna plugged in, adjust the antenna trimmer “C” for maximum volume with the radio tuned to a weak station between 600 and 1000 KC (see sticker on case). 157 收音机爱 好者资料库 RadioFans.CN
