Retrotechtacular: 934 MHz CB Radio
https://hackaday.com/2019/11/21/retrotechtacular-934-mhz-cb-radio/
The radio spectrum is carefully regulated and divided up by Governments worldwide. Some of it is shared across jurisdictions under the terms of international treaties, while other allocations exist only in individual countries. Often these can contain some surprising oddities, and one of these is our subject today. Did you …read more (https://hackaday.com/2019/11/21/retrotechtacular-934-mhz-cb-radio/)
