Measuring RF power for QRP radios The Q-Code "QRP" stands for "reduce power". It represents a growing part of the hobby where amateur radio operators try to use as little power as possible to communicate as far as possible. From $15 HF kits on eBay, HamShields, programmable crystal oscillators to unlicensed Part 15 HF operation, there is something at any price range for anybody. But how can you accurately measure these small power levels? Sure, there is expensive test equipment available for this. And you might be able to look at a power meter intended for higher wattages and guess...

His responsibility will be to improve examples, write new ones, expand...

Update: we now sell our Wideband Power Meter here! We have been asked a few times for information on measuring HamShield's power output in a cost effective way. While there are a variety of instruments available, most are well out of the budget range of a hobbyist. Sure, a simple analog power meter is cost effective, but a lot of them are not optimized for displaying power output under 1 watt (+30 dBm). This can make it a bit challenging for validating the power output out of any QRP radio, not just HamShield. So, naturally, we built our own! Using the board...
