Although not downloadable, these old magazines are easily readable online thanks to hi-res scans. And they’re always interesting.
The Google scans are complete and in full color – even the ads are there. Indices of most of the individual issues contain hyperlinks to feature articles making it unnecessay to scroll through numerous pages to get to one.
Also, each magazine is text searchable so you can search through the issues by keyword. Continue reading '91 years of “Popular Science” magazine now online'»
My initial entry into QRP was via two kits offered by Doug DeMaw W1FB (SK) 24 years ago – a small 40 meter transmitter and a 5-watt amp.
Along with the kits, Doug included a handwritten letter to me with words of encouragement for my new interest in QRP. I sometimes wonder how many others he started on a similar path, taking pen to paper in those pre-internet days before the convenience of cut and paste.

And a kit for polarography? Continue reading 'Three old Heathkit catalogs now online'»
Man, these old catalogs from Radio Shack sure bring back some memories!
I remember drooling over the DX-150/160 receivers in my early teens. Ditto for one or two models of those cool 8-track tape players and a lot of miscellaneous gadgets of antenna hardware. I guess my ham radio hobby was a preordained certainty.
Have a look at the early 1970′s scanners – a couple hundred bucks for a 5 channel scanner and you still had to buy the crystals. Money sure didn’t go far back then compared to what we can buy today for the same absolute $ amount.
Recently placed online are nearly all of Radio Shack’s catalogs from 1939 onward. Continue reading 'Old Radio Shack catalogs now online'»
