We've experimented with this new power multiplier since March of 2005, to generate more interest in the contest, and to encourage the QRPp contingent. Contest results seem to bear out our original hopes for this multiplier. What we've observed is that - up to a point - it somewhat mitigates the inherent disadvantages of running very low pwer, while not providing an overwheming or unfair advantage that takes the majority group out of the running. Once in that period, a QRPp'er took first place in the contest, attesting to their own skills and that of other QRP'ers. Even for those running "full gallon" QRP (5W), the comments frequently acknowledge the reward of digging out those QRPp signals. So the power multiplier will become standard fare for the Barbershop Contest.

Here's how it works:

The new power multiplier formula is designed to level the playing field for QRP and QRPp stations who run less than 5 watts. In the past, the power multiplier was computer based on pre-defined classes of power; i.e., 1-5 watts, 250mW-1 watt, etc. Turns out, the multiplier for QRPp powers and almost QRPp powers actually penalized those stations. With the new formula, the power multiplier is determined strictly from your power output. Halving your power doubles your multiplier. Half again, double again. The formula is designed to normalize power to the multiplier at 5 watts (which is "times 7").

The formula for calculating the new Power multiplier is simply:

Multiplier = 35 / Pout

As you see, if you run 5 watts, your multiplier is still 7. If you're running 2 watts, it would have formerly still been 7. Now it will be 17.5. If you use your "noggin" (as my dad used to say), there may very well be a power level low enough to maximize your points, but still high enough to attain QSO's with no problem. The trick is to predict that power level on any given night, and stick to it. Or else start low, and work your way up, reporting your highest power used.

Now, in case you're thinking impure thoughts (i.e., QRO), forget it. Multiplier for all output powers over 5 watts is "times 1". Period. This IS a QRP contest!

Barbers still use 3-5 watts, by rule. They aren't scored anyway. The exception is the designated "crew cut" barber. That's another story...

Again, as with all reporting in this contest, you're on the "Honor System". Always report your highest output power used during the contest. Either measure your power into a dummy load (if you can), or -if you can't - use the manufacturer's nominal rated power. Feedline losses don't count. Balun and tuner losses don't count. This is power out of the jack on the back of the rig, into the nominal load. You don't have to have NIST-traceable test equipment. Don't get crazy about it, but use your best informed and reasonable judgment in reporting your power. We will NOT be checking output powers, so if the lack of "policing" is going to make you uncomfortable when you come in second in scoring, don't even play to begin with. Keep it light... have another 807.

Because we have an "AutoLog" - accessed from the Barbershop Homepage - you need only be concerned about reporting your highest power, not calculating your multiplier. The Autolog will do that, and report it when the contest summary is generated a few weeks after the contest.

SPECIAL INSTRUCTIONS FOR THE AUTOLOG:

There are none. Report your highest power used, using your best and reasonable judgment.
