Early June 2022 I got a e-mail from OM Cor PA4Q that he has visited my website again and he wrote me that he started to make the Anderson PowerPoles his standard connector for all the hamradio devices running on a 12-15V DC. He upgraded his FT817 like I did but he also wanted to upgrade other equipment and for that he needed good chassis parts. In his option (and I agree) these are hard to find or way to expensive.

Fellow ham and hamradio homebrewer Gilles F1BFU  bought 2 adapter kits of my for his experiments. After a few months he ordered 2 additional kits for a friend and told me that he was working on a uSDX version designed by Barb WB2CBA design. He asked me if I could design a adapter that could fit the WB2CBA LPF for measurements and when I told hem I could take a look at it if I had a LPF PCB he send me a bare PCB.

After a few weeks I decided to setup the dish temporary in my backyard and made some cables to wire every thing up.. The original setup had a off focus placed 4.5 turn helix which was ok, but didn't give the expected  punch and  the signals where a little bit weak in SSB on the QO-100. Other operators told me that the signal was readable but not that strong.  So that was one thing to improve and the idea a of a new Helix feed was born.

A few months ago I ordered a  ATU100 kit from China (without a case), and on a rainy weekend I decided to build it together.  This ATU is equipped with a 1.3" OLEDd display and one thing I hate about these displays is that you almost can't install them without damaging the glass. Thinking about it, I decided that I need a 3D printable frame which puts all the mechanic stress on the PCB instead on the glass  . . .  Continue reading . . .
