Shortwave Radiogram

Hello friends,
I continue to be amazed by how well the MFSK64 mode (240 wpm) decodes, even with limited signal strength and interference from atmospheric or local noise. If you reports, it would be helpful if you can provide rough estimate of what percent of the text in each mode decoded correctly. Sometimes your images will be fuzzy, but the text, with its forward error correction, will often be 100%.

One interesting report last weekend was a tweet from Frederic @F4ECA, who tuned in using an old Panasonic RX-CW55L boombox (with shortwave bands), decoding (apparently via acoustic coupling) on an Android tablet with the TIVAR app. Also see the receiving setup, including loop antenna, used by Ralf @ralf_bender at his vacation hotel on the North Sea.

Scott Ontario 27 May 2330-2400 7780 Video

This weekend we will continue with a mix of MFSK32 and MFSK64. For image fans, the show will include eight MFSK images, including six in the higher resolution MFSK64.

Here is the lineup for Shoortwave Radiogram, program 50, 1-4 June 2018, in MFSK modes as noted:
