On 7180 kHz this morning about 0300 EST on SSB I heard an ongoing
transmission. It consisted of a male voice saying things like
"Kilowatt 7 radio lima, I gotcha". Then he would go on to the next
callin and say basically the same thing. Sometimes he would say
"Kilowatt 7 radio lima", sometimes he would say "7 radio lima 7084"
(although I wad recieving on 7180. There were lots of bravos and
charlies and zulus and all that. It sounded somewhat aviation but there
were no ATC instructions only what I mentioned above. I can't remember
the callins he was responding to because I was half asleep . The
callins were always short. No more than a few words.

Any idea what this was?

Amateur radio. There is a contest on this weekend.
