I’ve posted all this before, but it’s still important to me. It influenced my life to this day.
I think this is 1976 or so. My basement ham radio station (Amateur Radio), plus a CB (citizens band) radio. I had more antennas than those in the pic. They ran all over the yard.
Neighbors sometimes accused me of all kinds of interference on their TV’s and radios. It’s possible I did some damage to reception of local TV station channel 2, but it was best to deny it all with something like “I haven’t been on the air in a week” even if I was on the entire time.
1970’s were heavy Cold War, but I kept up with radio friends all over the old USSR areas plus the entire world. I loved them all.
What teenager would get up at 5 AM on school days? Me! I wanted a couple of hours on the air every morning before school.
I still have a valid license that I really need to put back to work.
My 6th grade teacher said one time, “it’s a lot harder to drop bombs when you have friends on the ground.” I believe in this.
73’s and 88’s

There are many Linux-based packet radio programs and suites out there. This is but one.
Wow, That formatted poorly. Apologies.
This article is ancient, but is a solid overview. The Linux support and tech have evolved substantially. https://www.linuxjournal.com/article/2218
