    Hi and thank you so much for the quick response.
    That clears it up nicely. I'd never heard of 'NINA' previously so that clears it up.

    Ok. Good. 600m is not far for line of sight. A reasonable antenna and 10mW would probably be fine, and 100mW plenty. ISM band in US is a good choice. I would however look closely at which is easiest,...
