WriteLog has an option for IDing call signs based on 'DE' or not. I use a
Super Check Partial database and turn off this feature, but without SCP it
would be useful. I think the WriteLog default is for it to be enabled, so
many ops may use it unwittingly.

Turns out that was W0YK, guest-oping at Dave's QTH last night!

I just LOVE Chen's posts! About time I think I'm understanding something
pretty well, another mini-tutorial arrives on the reflector that enriches
the topic further.
