for the other guys who like to 'roll their own' what do people use to switch the elements around the horn? i have a wiring diagram i like, but the relay choice is my inquiry. 3 DPDT open frame relays with 12-24 v dc coils? contacts good for ??? amps for 1.5 kw service? insulation good enough for 1.5 kw of RF from an amp tuned for the wrong frequency band? (like when you're 30 hrs into a 48 hr dx contest, short-handed, listening on a separate rx antenna) or do these all need to be vacuum relay$? 73, Dan, W5XZ _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
