The Yaesu FL-2100Z is a classic HF amplifier. It sits near the end of a long life line of multiple variations and models of the basic 811A or 572B triode valve, all using exactly the same grounded-grid core design, and all of them making nice big waves in the ether when fired up. I was…

The QCX – a Nifty Little Gadget

March 5, 2018 - 10:40 am

So yesterday (it was a Sunday) I had a lot to do, but nothing more important than to cut open the wrappings of the 20m QCX kit that I purchased from QRP-Labs a few months ago. Yes, it was still lying in its protective wrappings after all this time. Work is seriously interfering with my…

The Missing Q Codes

April 14, 2013 - 5:21 am

We use so few Q-codes nowadays! QTH, QRM, QSL, and thats about it. While there is an official list, some very useful Q signals have never made it to the ARRL’s and Amateur’s official list.
