New ! - KMPW Century Club

KMPW Century Club

The 1000 Miles Per Watt award is now taken to a new level with the introduction of the KMPW Century Club.
Available from November 2015, it is awarded to those who have contacted 100 countries where each QSO would qualify for at least 1000 miles per Watt !

The first person to be awarded this new certificate is JH1GNU who worked all 100 stations on 10MHz with CW.

As with all QRP ARCI awards there is no requirement for QSL cards or any electronic confirmation.
The award is issued free to active members of QRP ARCI (i.e. anyone with a current subscription to QRP Quarterly).
The cost for non-members is $10 (or join QRP ARCI to get the award for free)

QRP Frequencies

Center of Activity

These are not Calling Frequencies, they are Centers Of Activity - places where QRPers are likely to be found.

Of course, you may operate QRP anywhere that your license allows. If you have a VFO, then use it - but check around the QRP Frequencies on a regular basis.
