I had one of these when I was a kid, it was super heavy and built probably heavy enough to be driven over by a tank, I think it was FROM at tank.
It ran on 12vdc and had this cool removeable 12v electric generator that put out I think around 240VDC, it could be easily removed and at times I used it for driving nightcrawlers out of the ground to go fishing with them.
The unit worked pretty well, yet it was so noisy comparing against my handheld walkie-talkie I had. Walkie talkies were fun then, all the kids had them and we would play like spy games with them
I never really got into the ham radio thing very much yet the book The ARRL Handbook dated 1974 was my bible and was packed full of information.. I never did return that book to the library and finally - against my wishes - lost it probably 25 years later.
As far as the ham stuff goes, I had a bunk bed in my room for some reason, I would use the upper springs as an antenna and built crystal radios using galena crystals or even rusty razor blades, the only thing that sucked about this was that I could only get ONE station on it because it was so close to me! But hey! they played classic rock so it was all good
