I remember 78xx needs almost 2v above the output voltaje to works fine, If you want 12v and use a 7812, the component needs almost 14vcc.

I always used 10.5V as the minimum for lead-acid, SLA and AGM batteries, but I have no idea if that's 50%...

Yes! That's what I'm looking for. Where did you find the 3x 18650 battery tray?

That's what its all about when getting a radio for preparedness. It's good for establishing contacts with low power drain, key factor. It's small, lightweight and ultraportable, but you still have HF VHF and UHF and all the modes you can wish for.

Please tell us more. I am considering selling my two years old and unused FT817ND.
Why do you consider it not a good platform for Morse code (CW)?

Never thought of that haha. The noise is really irritating. But it could be it was so noisy because of the global contest ongoing? (king of spain contest)
