Re: QSO Ham Expo Buildathon
Rex, Does the kit still use the large-size Dole can? I see in your video it is about 2" tall, but our local Walmart either had the skinnier cans or the 5-6" tall variety. I am learning about cans more

Re: TTT EZ-build
Chuck, It may have tweeked back. A previous power reading was .56 watts which matches. That calls into question the accuracy of the watt meter at low values. Have to set up some standard tests maybe

Re: TTT EZ-build
John, Your scope indicates an Vrms value of 5.14V. If you trust the accuracy of the scope, the power would be 528mW. When dialed up it showed .74w into a 50 ohm dummy. Enjoy, ---John AC9UV

TTT EZ-build
Group, I played around with my TT EZ-build and replaced the final with a 2n2222a in a T0-18 case with a heat sink. I think I had the original transistor in wrong so got a much smaller output.
