Radio hams.

ZL6QH is someone's official NZ call sign. CQ is signalling morse code. The other abbreviations are also ham/morse related but I lost interest in that stuff 20 years ago. I presume someone's won a morse code speed challenge.

Well, there is certainly nothing l33t or new about this, the joys of ham radio.

CW - being continuous wave ( as apposed to CQ, which is ) is morse code. CQ is a all stations call, however in this case it is referring to a ham radio magazine heh.

The score card is here:

QSO = A conversation between two radio operators, i.e. contacts.

And you have a number of prefixes per country/region. As you can see in the winner, he has a ZL6 prefix, I know a couple of ZL4's as well. ( ZL being NZ, the number being a region within NZ )

So a score of ~12,000,000 means he contacted a CRAPLOAD of various prefixes, on different bands. And all by morse code.

that site is a gold-mine of geeky tech talk. I love it...

"The 15M band was not much better with DX QSOs being limited to the South Pacific area, a few VE stations, VU2UR, and ZC4VJ (1st QSO in the log at the start of the contest). I could not find any trace of G signals."

Pesky G signals.

From that link above I got this example:
Exchange: RS(T) report plus a progressive contact three-digit serial number starting with 001 for the first contact. (Continue to four digits if past 999 and five if past 9999.) Multi-operator, multi-transmitter stations use separate serial numbers for each band. Your log MUST show the correct serial number sent and received for each contact
It's all English words I know but I don't know what that sentence means.
