One nice thing about Raspbian and Raspi is that the "hard drive" resides
on a cheap SD card. And there's an easy way to clone the SD card. So one
could give you a fully-functional OS with JNOS installed and operating,
on a cloned SD card, and you'd have to buy the Raspi, but then just plug
in the SD card, turn it on, and go through some minor discovery and
configuration to "make it your own."
I just did this here in San Francisco with a friend (KJ6PTX Richard) and
we're still struggling with a few aspects of the configuration, but
largely it worked.
We have not told JNOS about the Internet. Instead the Raspi hooks in to
our wi-fi (in the house). I have interfaced JNOS to outbound email,
inbound email, and have automated the pickup of email and packet
messages using Python scripts that run every few minutes. (So there was
no need for us to configure a mail gateway or 44-net within JNOS.) We
use regular ol' email apps to send and receive our packet messages as
well as our Internet-based email (gmail, etc.) All from the little
Raspi. (Ah, and we also don't have any keyboards, mice or displays on
the Raspi. We view a virtual (VNC) Raspi screen from any other computer
The things I personally find more channelging are the radio and the TNC.
I use an MFJ TNC-X which is the same as the TNC-X ... plugs into USB on
the Pi. It requires wiring a cable to the radio, which I found almost
more challenging than the software, as the pre-configured cables didn't
work for me and I had to wire up one of my own. And you gotta put up the
radio and antenna. But that's what hams do, I guess.
Here's another suggestion. You might want to get a cheap SDR to do some
on-air listening. These SDR's can hear 2m radio pretty easily. I have
one here in San Francisco that can hear N0ARY (BBS) on Mt. Umunum about
60 miles away. Using the SDR you can perhaps gauge whether you already
can hear some stations somewhere. 2m is propagation-challenged, of
course, but maybe there's somebody in range.
