Slides:  Emergency_Power

Here is the document that Dan talked about during the presentation that describes the bicycle powered generator:  Bike Pedal Generator

Dan (N7XDL) lets us know what we can do to protect our equipment in the event of an EMP or CME.  Doomsday averted!  Dan's presentation was based on J. T. Smith's paper EMP Faraday Cages That Work.

Dan (N7XDL) gives his presentation on Grounding at the 6 August 2020 MARC Basic Topics meeting.

This post will be edited to include a link to the slides when they are available.

Here is the slide deck in PDF format:  APRS Overview

At our recent club meeting and potluck dinner, Gary Duhaine presented a short slideshow of some old radios he has collected over the years.  He also brought several of these old radio receivers in so we could look at them up close.  Please enjoy this slideshow featuring some of Gary's radios.

(Note, there were two versions of this slideshow, one of which had an audio component, but the audio component was extremely limited and also increased the size of the video by about fourteen times.  If we are able to get the correct audio component added to the video and get it sufficiently compressed, we will update this post with the new version.)

Jan presented on Electricity and Electronics for General class licensees at our club meeting on October 10th.  See the presentation on our Radio and Other Resources page.  Also new on that page is an expanded list of schematic components for your reference.

N7XDL (Dan)'s presentation at the October 2nd club meeting has been posted to the site... find it here:
