9、 Antenna Connector 1000 KC Signal Gen. Signal L* Before making this adjustment check the mechanical setting of the oscillator core H.” The slotted end of core should be IIS from the mounting end of the coil form. (This measurement is readily made by inserting a suitable plug in the mounting end of t

10、he coil form.) If adjustment is necessary, first dissolve the glyptal seal on the studs. Core ad justment should be made with an insulated screwdriver and core studs should be re-sealed in place with glyptal or household cement after alignment. *“L” is the pointer adjustment screw which is on the po

11、inter connecting link (see tuner drawing) and should be adjust ed so the pointer reads 1000 KC. (On first “0” of “100.”) With the radio installed and the car antenna plugged in adjust the antenna trimmer “G” for maximum volume with the radio tuned to a weak station between 600 ana 1000 KC. (See sticker on case.) it To tune to high frequency, put a 0.070” feeler gauge (or bare #13 wire) in slot against the high frequency stop. (See tuner pictures). Depress station selector bar and allow the planetary arm to run against the feeler gauge. Turn * the radio off and men on. 收音机爱 好者资料库 RadioFans.CN
