TELEPHONEE SET DING-A-LING Dear Half-Mast, Too many TA-43/PT and TA-312/PT telephone sets are sent off for repair 'cause a guy can't get a ring back when the G-42()/PT hand ringing generator handle is turned. It winds up one or the other callers has squeezed the S press-to-talk switch on the H-60/PT handset. This'll keep the phone from ringing. Would you tell operators hands off the switch when signalling a ring? JOINT EFFORT In case you haven't heard, it sure pays to take apart the sections of your whip antenna-such as the AT-912 and AS-1729 now and again to keep them from acting like they're welded at the joints. But there's more to it than just taking the sections apart and putting them back together. What you want to do is put some silicone compound on the threads before you join the sections. You'll find an 8-oz tube of the stuff on page 4.79 of Fed Cat C6800- IL (Jul 67). It comes under FSN 6850-063-1858. If you're in a wet place, it doesn't hurt any to pull this kind of maintenance every day. Otherwise, once a week is a good deal. SIUCONE THE THREADS
