Printable HF Transmitter


New advances in technology will allow HF radio transmitters operating on 13 MHz to be printed using electronic ink at a cost of about a penny apiece. That's a report from the BBC, as relayed by Newsline. The very low power transmitters are seen as possible replacements for QR (Quick Response) codes, those blocks of dots and squiggles that can take you to a company's website if you point your smartphone camera at them. Shouldn't take too long for hams to move them up from 13.560 MHz into the 20-meter amateur band! More details are available at <www.tinyurl.com/printed-transmitter>.
