Title: Question About Hammarlund Piston-type Trimmers Post by: KN4SMF on April 04, 2024, 04:34:17 PM The radio in this subject is a Hammarlund HQ-110A. The attached photo is of the piston-type trimmer for the 2mc end of the 160 meter band. It is a 1-8pf trimmer. Note that the piston is all the way in as far as it can go. Does that mean it is a full capacitance (ie 8pf), or is it at the least capacity? There is one wire leading to its transformer. I assume since there is no other wire, that the chassis is the second contact. Hopefull ysomeone can clear up these 2 questions. Thank you.
