[time-freq] Revised TADD-1 Manual uploaded

[John Ackermann N8UR]

I had a couple emails in the last week pointing out some errors in the
TADD-1 manual.  How they survived so long is a mystery to me, but I've
uploaded a corrected version of the manual to
http://www.tapr.org/~n8ur/TADD-1_Manual.pdf.
