Eltek inquiries – all the information I have is here on the website or in the User Guides.
If it’s not there, then the answer is: I don’t know.
Due to untrustworthy people, I do NOT provide MCU or touchscreen firmware alone for my Eltek controllers.
Do not ask, as refusal may offend.
Keep it well shielded from RF, and if you damage your controller you will need to replace it.
K3NG project inquiries – should be answered in the Kit Notes, or directed to K3NG’s Radio Artisan group on Groups.io
Sorry, insufficient time to be responding one on one.
