Hi Thomas

Back in the 1970’s, I used to enjoy hunting for “utility” radio stations outside the regular SWBC bands. When I came across a copy of the Utility DXer’s Handbook from 1971 recently on eBay, I couldn’t resist purchasing it. I have since made a page on archive.org for it to help preserve this unique piece of radio history. Anyone interested can follow this link and take a look at the world of utility radio as it was over 50 years ago.

Also, I have included links to some of the recordings and QSL’s from these stations that I have set up on the Internet Archive.

  • Cable and Wireless voice mirrors 1970’s
  • Tropical Radio Telegraph Company voice mirrors 1970’s

Wow, Dan! What a utility DXing treasure trove you’ve created on Archive.org. Thank you for sharing these resources and recordings with us!
