znalazłem tam kilka fajnych informacji nie tylko o "72"

73
Ramsey Moreau, W3WRE: "The traditional expression "73" goes right back to the beginning of the landline telegraph days. It is found in some of the earliest editions of the numerical codes, each with a different definition, but each with the same idea in mind - it indicated that the end, or signature, was coming up. But there are no data to prove that any of these
The first authentic use of 73 is in the publication The National Telegraphic Review and Operators' Guide, first published in April 1857. At that time, 73 meant "My love to you"!


72
QRPers sometimes sign off with 72 indicating they may be a mite short on power for a full 73!
But Kevin Cozens writes "In one of the magazines I was getting for a while from one of the QRP clubs (can't remember if it was from the Michigan QRP club or the G-QRP club) I learned of the use of 72 for the first time. Their use of 72 was based on the idea that "QRP operators do more with less". If you add that to the page you will have both a QRP as well as the QRO operators view of 72."
