Shortwave Radiogram, 24-25 March
Shortwave Radiogram this weekend is mostly in the usual MFSK32, but one item is in the twice-as-fast MFSK64 mode. MFSK64 is also fussier about the quality of signal it requires.
We will repeat last week's experiment in which MFSK32 text and an image are transmitted simultaneously: text centered on 1500 Hz and the image on 2200 Hz
A video of last weekend's concurrent decode of text and image is here...
A very cool news-consuming app for PCs or mobile devices could be MFSK only, allowing the simultaneous decoding of text and images, one on the left, the other right, or top-bottom. This could be used on shortwave, AM, or any other radio band.
