WHAT NOT TO DO AROUND HV!
You have reached the original WB0NNI scratch built RF amplifier site. With a few exceptions, the site remains as it has for the last several years - First, Rob, WB0RWH, is no longer 12 years old, but 18 and in the ARMY National Guard (not on the air much at this time); second, our newest op is 10 year old Laura, KC0YCB; and third, we are no longer in the QSL business.As always, you'll find a number of resources available for the homebrew design and construction of HF power amplifiers that employ glass triodes, tetrodes and pentodes (not that we're opposed to solid state amplifiers that have the look and and feel of a "George Forman Grill" - it's just that we're partial to equipment that looks like it might actually do something other than cook weiners at a backyard barbeque). Moreover, within the context of this site, we continue our original mission of resurrecting the practical and cultural aspects of ham radio, including a glimmer of the "tongue-in-cheek" humor, fun and excitement that has, for so many years, attracted innovators of all ages to the hobby.
With the exception of our endorsement of N3FJP's neat, easy to use Windows logging software, - where dedicated hams help keep value minded amateurs on the air, it's a "no digital zone", with absolutely no attention given the concept of political correctness. For that reason, the theory, practical experience and simple humor is entirely analog.
For those new to ham radio, a special welcome is extended to you! Here, you will find years of practical experience offered simply for the taking; the
kind of experience gained by hams that fearlessly applied theory and the use of available (often scrapped) parts and supplies (with mixed success and occasionally shocking results) to the design and
construction of a variety of station accessories. If you are just getting started and are looking around for equipment, we've added a new section to help you get off on the right foot. Your First Rig provides info on a number of older rigs on the market that will get you up and running with a great signal, and without breaking the bank. Once you know what you're
looking for, you might check out Associated Radio. And, if its a VHF rig, check out USEDRADIOSALES. In Parts is Parts, you'll find information on
salvaging parts and supplies, as well as articles on a variety of ideas such as how to wind your own chokes, and creating custom meter faces. In Reference Material you'll find an assortment of resource material that will be of use if you're seriously interested in home brewing
equipment and accessories. And, if you're looking for the highest quality, full color, custom QSL Cards, then check out our QSLWorks! We established the business as a way to help support this site and are currently the only QSL printer offering premium, full custom, full color QSL cards in the US. According to the feedback we've been receiving, we are also very likely one of the Best.
So, grab a fresh cup of coffee (or stick with the one you've got), sit back and enjoy. Check out the tutorials, projects, and ideas that are featured.
And, if, in the process, you think of something you'd like to see added, or perhaps make a comment on the site, or even better yet want to meet any of us on the air, just drop us an e-mail at your
