Due to the general disarray of the supply chain I am unable to order a lot of the parts need to build the original CTR2 system as published in the Sept/Oct 2021 and Jan/Feb 2022 issues of QEX magazine. I’ve decided that instead of redesigning the system to use available parts it is better to just remove the CTR2 system from the market. I regret having to make this decision but feel it is for the best.

I am maintaining a stock of boards and parts to support the systems out there.

I intentionally designed CTR2-Mini and it’s support systems to use readily available parts. If you’re interested in what it can do, visit the CTR2-Mini pages for more information.

Please feel free to contact me if you have any questions,
