Recently, someone donated an entire TS-820 station to our Ham Radio at the Hands-On Museum project. The equipment included a fully decked-out TS-820, plus a lot of other stuff from that era (the late 1970s), including a Heathkit code practice oscillator, a Handbook, and other assorted books and materials.
I’d looked through this stuff before, but somehow I’d overlooked the Heathkit Amateur Radio Log. Here are a couple of scans I made:
Kinda cool, isn’t it? I’d never seen one of these before.
