http://www.qsl.net/ke5fx/ Thanks for the heads-up. That's v1.05,
the Jan 14, 2006 edition? Which program was updated to fix the
phase-noise problem? The pn program's source code says 13-Jul-05,
although the pn.cpp file date is 12-Feb-06.

The broken version was 1.05, but I "slipstreamed" the fix into the same
release without updating the version stamp.

I really should've bumped the version number when I posted the fix, but
it'll be pretty obvious if your copy has the bug. It will appear to
work, but it will always start the PN sweep at 0 Hz rather than the
minimum offset you specify. That makes the sweep take much longer than
necessary, and the trace information at offsets below 10x the
analyzer's minimum RBW is meaningless.

Basically, if you downloaded it around the time I posted all those
auctions, you probably got the bad version.

I like the part where you get the "number of 1000-ns intervals
since 1-Jan-1601 UTC" :-)

Heh... I've wondered where Microsoft came up with that; it might have
come from the Unix world. There's a lot of weirdness in the calendar
business, and it's usually less arbitrary, but more obscure, than it
seems at first.
