This is a series of 6 quick talks at the DCC. They were an impromptu fill-in for a presenter who took ill, recruited with just a few hours notice from the audience. It worked great, and will probably become a regular feature of the DCC. HamRadioNow is presenting full-length video of all the 2017 DCC presentations, as quickly as we can edit them.
