Last weekend’s EasyPal experiments resulted in the same high failure rate that we experienced several months ago during our first round of EasyPal transmissions. That is in addition to Mac and Linux users who were not able to use EasyPal because it is currently only available in Windows.
But there were some successes with EasyPal, resulted in a brilliant image of the VOA Radiogram test card. Most of these were from North American listeners, but the image was also successfully decoded in Poland, Greece, Italy, Germany, England, and Scotland. See examples.
We also experimented with MFSK32, MFSK64, and MFSK128 images at X1, X2, and X4 images. The X2 and X4 images were somewhat (X2) and very (X4) fuzzy. The X2 speed in MFSK64 might be useful when a larger image must be transmitted. See examples
