Ha! ... many do seem to thunk, don't they? The Brownings had a capacitor that caused the receiver to mute slowly so each transmission was preceded by brief audio feedback. A popular mod was to install a DPST center off toggle so you could switch between two different caps for a long ping and a short ping, or turn it off altogether.
Really skillful ops would wave the mic in front of the speaker causing the feedback to warble as it died. Hence the name "Screaming Eagle". ;-) 73 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Larry Keith Sent: Tuesday, April 04, 2006 12:05 PM To: Discussion of AM Radio Subject: [AMRadio] ping vs thunk! "CQ CQ CQ from K4MO .... <ping!!>". Hmm. I always thought that AM transmitters should have a "Thunk" sound when when you let off the XMIT switch.. "CQ from KQ4BY ... THUNK!" 73, Larry KQ4BY Larry Keith 231 Shenandoah Trail Warner Robins, GA 31088-6289 [EMAIL PROTECTED] 478-329-0030 __________________________________________________ Do You Yahoo!? Tired of spam?
