MF / LF presentation redux from Hamcom 2016 in Irving, Texas

– Posted in: 630 Meter General Topics, 630 Meters

Hamcom 2016 was a great opportunity to expose a large number of people to the magic of the world below the AM broadcast band.  Over the weekend, several hundred people attended presentations provided by several active operators and based on the conversations I have had and emails that have since been received, there is a tremendous amount of interest in the North Texas area.  Also notable is that there are a lot of people who are building stations and preparing for a 630-meter band under Part-97 right now in anonymity.  Opportunities like this weekend really give me a chance to “take the pulse” of the amateur community and I am here to say we are in a very healthy situation.

I am eternally grateful for the willingness of these presenters, whose content is listed below, to take time out of their busy lives to share this valuable information.  THANK YOU!

A Survey of the 630-meter Band and its Practical Applications

Note that my audio has some edits to remove questions that were dead audio.  Some of the edits are better than others.  This was the Friday program, which was a lot more “seat of my pants” presented than the concise format content from Saturday where I had a hard stop at 9:50 AM CDT.  The presentation contains embedded hyperlinks that do not work in the PDF version and reference slides that are placed at the back of the presentation so the organization, as it is laid out in the PDF file, may be a little different than the content suggests.  Thanks to N6LF, WA3ETD, W0YSE/7 for allowing me to use a few of their slides in this presentation.
