Jon,

I thought others may be interested in this little gismo.   I posted it to the 
personal space at my ISP.  Perhaps you can post it on  NLRS if you think 
there might be interest.  If anybody has any questions,  they can contact me  
directly.

Thanks

dipole, 80M vertical, whatever) I get a nice  10MHz output at about -20dBm, which 
is more than adequate to trigger my  frequency counter.  Then, using the 
trimmer on the back of the counter, I  can adjust it to exactly 10 MHz.  As long as 
the announcer isn't gabbing,  the process works pretty slick.

isn't that  accurate due to skywave propagation.  Apparently, phase inversions can 
 occur and jumble up the signal.  So we talked about it a while and came to  
the conclusion that the maximum inversion was on the order of maybe 1 cycle 
out  of 10 million cycles.  Lemmeseeherenow....  My instruments are only  
accurate to a reasonable number anyway.  And he's talking about 1  Hertz!  I think I 
can live with that!
