HamWAN

Some interesting stuff in this. Mostly the antenna modeling, and upcoming work that he mentions.

I have been saying, if I had to start all over, the Mitrotik Groove is what I'd go with over the Bullet. This kind of confirms that.

I'm also curious ...

DSD

For anyone who hasn't played with Digital voice, there is a very handy software tool called Digital Speech Decoder that can decode a variety of digital formats.

Several years ago I stumbled into it. And the only thing that was digital at the time in the area was St. Vincent's hosipital, then later ...

OLSR technical stuff

I was talking to KB8ZXE and we really have no experience with dynamic routing. We both came to the conclusion that a video where someone explains what nodes they are going though and shows a traceroute and bandwidth test would be helpful.

Scrays link stats

Internet has been restored to the hill which brings the IRLP on 444.775 back on-line. Our existing link to St. Norbert's had to be removed for their remodeling project. The new link is using the same equipment as before but is now at a club members home.

Re: Antennas
