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
