PSK Soundcard Interfacing

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.

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.

Radio Amateurs Supporting a Mission in Space

This video is from the launch of STS-127 on June 15, 2009.

Atmospheric Neutral Density Experiment – 2 (ANDE-2) consists of two microsatellites launched from the Shuttle payload bay, that will measure the density and composition of the Low Earth Orbit (LEO) atmosphere while being tracked from the ground.

Data will be used to better predict the movement and decay of objects in orbit.

Originally designed as passive payloads, both satellites were turned into research projects of various participating highschools and universities. Radio Amateurs participated in the program as they acquired all satellite data transmitted via radio.
