There was a caveat that >you had to be careful to get a live broadcast. I commented on this in another post. The use of frame syncronizers at TV stations and the use of live satellite broadcasts by the networks have made this technique obsolete. The signal you receive from your local station, even during a network program, has passed through one or more frame syncronizers before being aired. This changes whatever accuracy the original signal may have had to the accuracy of the local station's sync generator. Usually these are simple crystal controlled generators with no more accuracy than your home counter. >Can anyone give me a reference to this?

Check 73 Magazine, there was a construction article on this subject within the last few months. Please be aware however, as the author of that article was not, that this technique is now worthless due to changes in the operating procedures and equipment of the networks and the local stations. >Has anyone tried this in the past?

Many newer systems have that built in. ------------------------------ Date: 3 Apr 91 02:03:49 GMT From: swrinde!zaphod.mps.ohio-state.edu!sdd.hp.com!hp-col!col!bobw@ucsd.edu Subject: Licensing Philosophy?

There's a good article in the March 1991 CQ that covers this. All VECs should have received a letter dated Dec. 14, 1990 covering the subject. In general, the No-Code Technician licence is tested just like the (Code) Technician, but without element 1(A), 5 WPM Morse. So No-Code Technician takes elements 2 and 3(A), given as usual. The FCC is soliciting informal comments on names for the new license. "Tech Lite" has been suggested.

Hey, now that DDS is such a popular buzzword and reasonable systems are practical, building a direct digitial synthesizer for this (and other) radios ain't such a bad idea. I'd guess one could build a remote, <1Hz step VFO with the stability and phase noise characteristics of a crystal without special magic. Plessey makes a chip (dunno how much costs) that would this task pretty easy.... 'course it requires the use of a CPU, too. -- * Dana H.
