21. But…I won’t be heard! Oh yes you will! Oh yes you will! Math class is now in session Consider… Consider… –One S unit on your receiver is 6 dB. –Halving your power is only a 3 db loss. –Quartering your power is 6 dB loss and therefore a one S unit difference. –Let me repeat that: using ¼ of your power reduces your signal only 1 S unit.

22. More Math (sorry…) –If a 100 watt signal is received as an S9, then –A 25 watt signal (¼ of 100 watts) will be S8 (-6 dB) –A 6.25 watt signal (¼ of 25 watts) will be S7 (-12 dB) –A 1.5 watt signal (¼ of 6.25 watts) will be S6 –A 5 watt signal will be just under S7

23. There are QRP Calling Frequencies (where to hang out to improve your odds) BandCWSSB 1601.8101.910 1.843 Europe 803.5603.985 3.710 US Novice 407.0307.285 7.030 Europe 7.060 7.110 US Novice 3010.106 2014.06014.285 1521.06021.385 1028.06028.385 28.110 US Novice

24. One more QRP difference Some QRPers sign with 72 instead of, or in addition to 73 when signing Some QRPers sign with 72 instead of, or in addition to 73 when signing –To acknowledge the QSO using QRP power –Kinda like a not-so-secret hand shake.

32. In Summary Try it from home by simply turning down your power Try it from home by simply turning down your power Try it from a park bench with your portable rig.
