Pretty interesting and coincidentally I was looking at another page from Michigan Ares about Jnos on the pi


This was something I was considering  for my station. It old and needs an update to be useful again. 

I have two totally separate packet stations set up. One for 2M @35w and one for 70cm @15W both feeding copper pipe j/poles on the roof

I have a bunch of computers I keep alive for work so I already have a 3kw UPS and a 11kw backup generator. This station is in Orange County NY FN21uh

Big problem is there is no connection between them or to the internet. It’s time to rebuild them and make it useful. 

Each has a tnc-pi sitting on a pi-b and I’ve been wondering if I should stack the two tnc’s on a single new Faster pi....

I would prefer jnos on a pi

I don’t have a static IP for my internet but it only changes about twice a year. I do have a dynamic dns setup that seems to have worked fine on a web sdr setup for the past few years 

I’d be interested in any guidance for a setup that would make this station useful to the community.

> Well, quite simply, JNOS is the "Swiss Army Knife" of Packet Radio!!! Because it can do just about anything. It's a TCP/IP router, firewall, BBS, SMTP/FTP/WEB server, and talks AX.25, NetROM, and TCP/IP protocols. And it does APRS and WINLINK. Read on....
