About 3-5 miles, with yagis. I would figure 1W or less, absolutely,
though I am expecting some attempts at tampering so I might want to
make the receiver "deaf as a post" and yell at it.
>What is your expected TX time on the link?
For thermal concerns, I would assume continuous.
The control link wouldn't be up unless I needed to change something,
and then only for a minute or so, but I would want to use the same
radios throughout, in case I need to swap something.

Control link will be one-way, intermittent.
IRLP will be half-duplex AFAIK. Might go full dup later.

My priorities are 1: Control link, 2: IRLP, 3: removing the
controller from the repeater site, and operating just with links.

Ok, I wasn't aware that there was a local plan. I'll check with them.

Might as well let others learn/kibitz :)

Well, I do need to get to both.
I could do IRLP on 440 as well, I'm less concerned for security there.
