archive of scanned issues of a popular ham radio magazine from my childhood, "73 Amateur Radio".
They come up in a rather strange order, like all the Decembers together, but they are high resolution scans saved as PDFs so perfect for reading on an iPad for inspiration.
It's a great way to see the march of technology from 1961 through to 2003.
Early editions are valve technology, later there are hybrid rigs with solid state drive to a valve final. Gradually digital frequency displays creep in and there's a marvellous time when having an LED is a feature worth advertising.
There's lots of ads featuring girls with big hair caressing equipment.
This collection, for me, represents what may be a golden age, before everything in electronics just turns into computer chips surrounded by surface mount components.
A few of the home brew group seemed interested in grabbing the set for later viewing so I wrote a little python script to download them from archive.org to share around. (I think I'm being throttled but it's going pretty well).

If you stop the script and re-start it, it will not re-download any that it has. Otherwise it's pretty basic stuff.
Thanks archive.org! Look out for the ladies with tech:
