I found a Cavalier King Charles figure stamp, a "This Envelope Sealed with Dog Slobber" stamp and a "I'd Rather be Flying" stamp, several Ink Pads and a re-inking roller in Black. That is only in one drawer. Willis 'Cookie' Cooke,

The LP-100A is not a dummy load. My 20-year old inexpensive MFJ dummy load does a good job for that. (But note it has never been abused, such as running power into it until it gets hot or smells.) A well designed dummy load will have very little reactance from stray capacitance or inductance. That leaves only the value of the resistive element, which you can check with your DMM. It's the resistive element that is most susceptible to damage from overheating it, just like any other resistor. For calibrating the wattmeter in your K3S beyond the factory setting, whatever makes you happy is perfect. There is no operational or performance advantage to "improving" the factory settings. The LP-100A claims 3% power display accuracy which is much better than most (if the claims are true). For example, the ARRL lab is quoted in their manual saying "They specify their measurement error for power as +/- 5%, and for PEP power, +/- 8%." Note the +/- meaning the power error may vary by 10% for constant carrier and 16% PEP. Those are much more typical values for good, even lab quality power measurement equipment. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Clay Autery Sent: Tuesday, April 26, 2016 6:50 PM To: Elecraft Reflector Subject: [Elecraft] Wattmeter for K3s Calibration Would the LP-100A meet the accuracy/precision requirements to do the power cals outlined in the K3s Manual? If not, please supply recommendation for one that will do the job adequately.
