[time-nuts] crystal oscillators & TPLL

[Gerard PG5G]

Warren,

I couldn't care less whether your or any method works or not. I have no 
vested interest or opinion whatsoever.

I can say however that in the short time I have been on this list I have 
grown very tired of the way you hijack any thread that comes along.

Most people who think they have something that is better than ANYTHING 
done before have one of two motives: fame or fortune.

If you are after fame, build one of your TPPL thingies, test it (or 
better yet, have it tested) and submit results to a peer reviewed 
magazine. Glory will be yours.

If you are after fortune, build one of your TPPL thingies, test it (or 
better yet, have it tested), manufacture it, sell it. Money will be yours.

So I guess what I am trying to say is: build one of your TPPL thingies 
and have it tested.

I wish you either or both, fame and/or money. I honestly do. However, 
until you have decided what you want out of this and how to go about it, 
please leave us alone.

Thank you.

SK PG5G
