Yesterday a bunch of people got together to build up their kits of 5 watt
digital radio transceivers!
These are HF ham radio transmitter/recievers that connect to a computer
over USB, and allow communication on digital modes on what we call low
frequencies these days (but they're also called Shortwave even though
they're now the longest waves we use). Technically one is supposed to have
a ham radio license to transmit on these frequencies, although anyone is
allowed to listen in.
This is the kit they were building:

We used the video microscope and all six soldering stations! It was the
most soldering happening at the same time in sudoroom in a long time. The
event will happen again on Wednesday.
