guys and gals.....Im new here

It means do it "Quietly, No Hu-hu".


Well, you *asked* grin


Seriously, it is just a "code". an *arbitrary* symbol to which a particular
meaning has been assigned.

"Q" codes date from the days of Morse-code communications, where there was
a definite performance advantage to be gained by having "short-cut' symbols
for many "common" messages/phrases. example: it is *much* faster to
send the 3 Morse-symbols for "QRU" than it is to transmit "I have no traffic
for your station".
