Here's what I do:
If I find a frequency I think is not in use, I send a single DIT.
If that doesn't generate a response, I send DI-DIT DIT or "?", depending
on my assessment of conditions.
If that doesn't generate a response, I send my call -- ONCE.
If that doesn't generate a response, I send my "Short CQ" message.
If that doesn't generate a response, I send my regular F1 "Long CQ".
If that doesn't generate a response, I turn off the rig and go to bed
because I must not be getting out....
The problem I see with blindly following the dictum of starting with a
"QRL?" is it can wipe out most of the exchange that actually may be in
progress when you think the frequency is empty. Even worse is the poor
operator who sends two or three "QRL?"s in a row.
Many times I've found that a single DIT will get me a DIT in return --
which is all I need to convince me I should move on.
"QRL?" was a wonderful Q-signal when I was a rag chewer or on the Novice
bands. It is totally inconsistent with the pace of today's contest
