4、Hazeltine Test Loop Model 1150 or 3 turns of wire about 6 in dia meter placed about one foot from thq set loop. The alignment procedure should be repeated in the original order for greatest accuracy. Always keep the output from the signal generator at its lowest pos sible value to make the AVC action of the receiver ineffective. 22 i 收音机爱 好者资料库 RadioFans.CN
