"Three days ago.  Attached.  Not easy to read."

>From top to bottom, looks like EH in FSK QRSS, SIW auxiliary ("slash" mode), 
SIW in regular QRSS with the "S" preceded by the plain ol' CW ID (CW looks 
as if it might have been audible), and maybe USC in FSK QRSS (broken up 
somewhat by fading).

::: The limit is in the 20 - 30k range ...

"Yipes!  Dropped quite a bit over the years..."

Actually, raised from zero...for a long time, this reflector had no 
attachments at all.  When qth.net experienced the big collapse way back 
when, and we filled in at LWCA with a reflector for a couple of years, 
that's when we implemented file attachments which could be up to 100 KB at 
one point.

I closed down that reflector because we couldn't afford a private server 
with its own unshared IP address, which are two of the first necessities for 
an e-mail group trying to cope with spam filtering these days.  When we all 
came back to this reflector, the good folks who run it eventually instituted 
the file attachment capability we now have, for which I am most grateful.

You can actually pack a lot into ~30KB.  It may require cropping out areas 
of the image that don't provide important detail.  It may involve shrinking 
the image some, if that doesn't make it too hard to read.  But probably the 
most powerful tool is the compression quality setting available in many JPEG 
image editors.  Using that control carefully was how I managed to get the 
image attached here to pass the reflector when I first posted it back in 
June.  And, there were a couple kilobytes to spare.  I could even have made 
the image a bit larger if I'd left out all the added text, which really 
piles on the overhead in JPEG compression.
