I'm almost surprised that people use these things for voice calls any more, I thought that they were basically sold on all the other things apart from such old-fashioned use? -- Regards, David.

Knowledge is a measure of how many answers you have, intelligence is a measure of how many questions you have. ***** Moderator's Note ***** "Old fashioned"? "OLD FASHIONED"?? David, you just made my day. Cell calls are now "old fashioned". I can tell you how an SD 96251 works! Given a spark coil and a doorbell buzzer, I can make a transmitter that will blank out AM radios for hundreds of feet! I listened to "Pancho and Lefty" when Eric von Schmidt was singing it! I know the MORSE CODE, Dave! Bill "Moldy Oldy" Horne Moderator
