Of course the tuner was feeding a 22-foot WHIP as well as a "ship" <G>. Sorry 'bout that. (Dang spel chekkers don't warn me when I type the wrong word...)
Ron AC7AC -----Original Message----- ...As a practical example of what RF voltages can do, on large ships I often encountered SGC unbalanced tuners mounted on the ship's forward stack (funnel) feeding a 22-foot ship for the 2182 kHz emergency SSB rig on the navigating bridge. A 22 foot antenna is very short for 2,182 kHz (just above the Ham 160 meter band) and, in spite of the tuner being a sturdy, commercial unit fully sealed against the elements, it wasn't a surprise to see them 'go up in smoke' at regular intervals. Opening the case one would find charred relays and lots of carbon. That was at less than 100 watts PEP sideband. They tuned at low power but they were pushed to their limits at 2182 into a short whip. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
