Thanks, Ed - that post is yet another 'keeper' from you.

They may be getting their timing right for P49X because you are stacking 
almost constantly, so callers can always hear what they need to do. But 
I fear they are treating P49X as a special case.

As a smaller station that can run steadily but doesn't always have 
multiple callers, I was actually struck by how *few* calling stations 
have got the message to spread their calls over TIME. Far too many were 
calling exactly in sync, and then going silent in sync.

Over the weekend I tried to follow Ed's advice to tough it out, and wait 
in silence for one station to break ranks and call again. But very often 
that didn't work because nobody even tried; or if one station did call 
again, the other(s) immediately fired up as well.

Another point that doesn't apply to the big guns is that smaller running 
stations have to be extremely careful about leaving the frequency silent 
for too long, become someone else will try to steal it!

So "Spread your calls out over TIME" seems to be our next big education 
campaign for the casual callers... and it won't be complete until they 
are doing it for everybody, not just the big guns.


Moving on to W7WHY's point about not calling 'stations who stack', I'd 
have no hard feelings about that... but please try at least once!

Stacking worked much better for me when configured for 'first in, first 
out' - in other words the strongest, slickest, smartest caller always 
needs to be worked first because those stations are also the least 
likely to wait.


As for working dupes, my policy is:

1. The first time they call as a dupe, call CQ again. Given a second 
chance to print my callsign correctly, many duplicate callers disappear.

2. If they still call again, work them. They probably have a good 
reason, so don't ask questions - just do it.

3. If a station calls yet again, with already two good QSOs in my log, 
then call CQ right in their face.

4. If they still persist and are jamming out other callers, then engage 
Ctrl-K and send them a Personalized Greeting Message. (Usually we only 
reach this stage on day 2, when beaming towards countries that are famed 
for enjoying a looong and well lubricated Sunday lunch.)
