You're not alone! Pinball and ham radio are two of my all time favorite hobbies.
Both involve finding, researching, restoring and the joy of using great stuff.
The past few years have been more into ham radio collecting than pinball.
Can't cram any more pins in the house. Restored radios can be stuffed under pins.

I've met several pinheads that are laso hams over the years. There are many
similarities.

Was also into RTTY back in the 1970's and jumped back in the past few years.
Have managed to save quite a few TTY machines from being junked. If you still have any interest
there is a 24/7 internet site streaming baudot news stories; www.rtty.com
Not as much fun as copying TASS, UPI, AP and many others that used to broadcast
news stories on the SW bands but a great way to keep these vintage machines
running. There are still a bunch of m15's and m28's lurking in the back of peoples
garages just waiting to be rescued. On the air ham nets exist too, one is the ClatterNet.

Amateur radio is a popular hobby for the young and the retired. There are a lot of folks
that had the interest but no one to help them out. Seek out local clubs
as there are usually a few that would be very happy to welcome anyone with an interest.
Just met a guy that finally got his license at 75 yo. I've been a ham for about 50 years
and many of those years was inactive but always came back.

Not much activity here on 2, or 440 either. Upgrade your license and
join us on HF. As we approach the peak of the solar cycle HF is really
hopping now. And if you enjoy fixing up dead pins there is far more interest
in ham radio now for those of us that enjoy finding, restoring and using
vintage gear. Its more plentiful than ever.

And you are right...if we don't use the freqs others will. We lost a big
chunk of 220 MHz that way.
