Here is another video from Randy, K7AGE looking at homebrew and commercial soundcard interfaces for PSK31, RTTY, SSTV and other digital modes.

I’ve been using PSK since 2001/2002 and it is a great digital mode for hams to use. PSK31 was developed by English amateur radio operator Peter Martinez (G3PLX) and introduced to the wider amateur radio community in December 1998.

I posted a video on September 25, 2009 about “PSK-31 Introduction (Receiving)”. You can find it by searching for “PSK” in the search box above, by clicking on the video tab above or go to the Archive page under the “Site” tab.

This is a video of the K5D Desecheo DXEpedition from February 2009. This was a relatively easy DXEpedition for us to work in the US.

Thanks to the crew that provided us with this DX entity and for PY2MAJ for putting this together!

Here is part II of the “Featured Video” that shows Amateur Radio equipment used in WWII. This video is sponsored by Hallicrafters, and if you’ve been around awhile you know how important Hallicrafters was in the history of Amateur Radio.

This video demonstrates the Hallicrafters HT-4 that had been used by amateurs prior to WWII and modified to fill important communication needs.
