[Elecraft] K3 Firmware upload

[J F]

I have to say it sounds like the daily, more or less,
firmware uploads execute flawlessly. Haven't seen a
negative word on the subject...

I'm wondering what the process involves. Is it similar
to say the Ten Tec Pegasus or AmQRP micro908 uploads?

Would it require a direct connection to the web or
could you download the upgrade (like N1MM) and install
it via any computer connected to the rig?
