Hi - I'm John K9JEB, Amateur Radio Operator from Redmond, WA USA
     About K9JEB.com (It's just ME - the one guy...)

  I design and build circuit boards primarily for power distribution, using the standard Anderson PowerPole connectors that HAM radio operators (and a lot of other fields) use. I have designed these circuit boards because I needed them - and now sharing the finished product with others who do also. We need our equipment to communicate, and I want HAMs to get what we need at the lowest possible cost.
  These boards are sold as kits, to encourage the spirit of invention and self-reliance that the tradition of HAM Radio has had from its earlyiest beginnings. We used to build our own equipment - not buy it! I encourage people to try building these kits, but I know they can be difficult if folks don't have the experience. I still want to help make sure it works, so some folks who just couldn't get it working send it to me, and I am happy to "fix" it if something just didn't work out.
  I use low-cost, commodity-type components, to keep costs low, yet still be reliable. I personally test almost every component that goes in your kit - I want your kit to work just like you expect. I pull, pack, and ship every single kit myself personally. When you get something in the mail - I personally packed it just for you!
  The philosophy here is to provide a much lower cost product than "retail" for HAMs who want to "build their own" rather than buy something mass-produced. I do actively support other HAMs that are in business to make money, but that is not the purpose of my site or products. When I must raise prices (like I did December 2020) it is a specific impact of inflation, and market prices for the commodity-level components I use.
  These kits are sold at the very lowest possible margin, and savings are passed on directly to customers. This is my hobby, not a "business" - most of my time and expense in design, assembly, website, etc. is unpaid and actual "profit" from sales is very small. The few dollars that do end up as extra are put back directly into development, buying and testing new components and designs.
  I don't advertise anywhere, so if you get here I hope it's by a recommendation from someone you know who has used one of these products! If you have any kind of an issue with a product, I will always make it right for you. I hope you enjoy your product - and tell a friend!

In my spare time, I build UHF/VHF antennas and design electronic circuits like the Power Pole Distribution Center - for the advancement of HAM Radio.

This board fits on top of a 9/10Ah gel cell battery, and charges the battery from the external supply while the supply powers attached radios etc. When the supply is removed, the battery continues to power the equipment. When external power is restored, it again charges the battery.
