I just got PSK31 working with my radio, and made a very inexpensive “interface” if you can even call it that. I worked a couple stations tonight, and this is a video of the one I managed to get recorded on air. Made contact with VE6VIS. Disclaimer, this is probably one of the more boring, and long videos I’ve made.

The tower monkey is my brother Tim KE5CFZ..We both work for a ham radio store called Kcomm here in San Antonio, Texas..One of the enjoyable things about our job is that we get to go on field trips, installing towers, antennas as well as removing antennas & towers..We also do mobile radio installs both at the store as well as in the field..

A Guide to Being a Skywarn Spotter
The United States is the most severe weatherprone country in the world. Each year, people in this country cope with an average of 10,000 thunderstorms, 5,000 floods, 1,200 tornadoes, and two landfalling hurricanes. Approximately 90% of all presidentially declared disasters are weather-related, causing around 500 deaths each year and nearly billion in damage. SKYWARN® is a National Weather Service (NWS) program developed in the 1960s that consists of trained weather spotters who provide repo

This video shows a few ways that you can monitor your ham radio transmitter with an oscilloscope. Look at the RF carrier, the carrier envelope, the amplitude demodulated signal, as well as linearity “trapazoid” patterns (please see below). It shows a simple circuit I put together for a local ham radio club meeting and presentation. I put this circuit together to show the radio club members examples of a sampler and a amplitude demodulator. Of course, since these were built onto the same “demonstrator” board with a common RF input, the linearity can not be measured with this since any non-linearity in the output would appear in both sensors. This is indicated by the notes in the video. In order to truly measure the non-linearity of an amplifier or a modulator/exciter, the X-input would normally be driven by the baseband signal, or the demodulated input to an amplifier, etc., and the RF output would be sensed with the sampler and applied to the Y input of the scope.
