What is your definition of "Packet Radio"? The technology is heavily used for APRS. Also WinLink can use packet technology for its transmissions. There are still digipeaters up in areas to help extend the signals. Some ARES/RACES groups do exercises where they transmit information using packet technology to make sure that the information is passed accurately. I understand that there are still a few packet BBS out there, but none are in my area that I'm aware of.
There are little 'pockets of packet' around the world. They are sparse. You'd have to check locally to see if anyone is running straight AX25 in your area. We have two AX25 bulletin board sites active on 145.01 mHz near me in Winnipeg, Canada.
It's not like it was back in the 80's but I can fire up a terminal program then connect to, and send and receive messages on the systems. The long haul message forwarding takes place over the internet now and not on HF as was used in the past.
I forgot about satellite, think I did it once, really embarrassed, as I thought some one was using 145.850 instead of 144.850 and sent a message to inform them of there mistake, but it was no mistake it was an English school teacher talking to schools from Mir space craft, ups!
Only heard one guy using 2 meter or 70 cm in this area full stop, so it seems amateur radio for me is dead, I have had a good innings really started around 1984 as a VP8, then GW7 and then VR2 and back to GW7, but my move from North Wales to Mid Wales seems to mean unless I start using HF amateur radio for me is finished, the handy is used to listen to local heritage railway, but that is about it.
