One feature of the MFSK digital text mode is that it can also be used to transmit images. Until recently, only the MFSK16 and MFSK32 modes could have been used to send images that display correctly. 

An “alpha” version of Fldigi, 3.32.76AB, can now transmit and receive images in MFSK64 and MFSK128 without the skew and discoloration previously experienced. These faster modes to not transmit the pictures more quickly, but they do allow greater resolution.

Michel in France decoded this MFSK64 image from VOA Radiogram, 21 Sept ember 2013, 17860 kHz, using Fldigi 3.21.75:

And, from his recording, the same image using 3.21.76AB:

Below, from a receiver in Greece, is the CNBC logo transmitted in MFSK128 and decoded by Fldigi 3.21.76:

And, as decoded in the Netherlands, the same logo decoded by 3.21.76AB

In another type of comparison, Roger in Germany compared the images received via shortwave on VOA Radiogram with those obtained directly from websites.

First, the Duck Commander promo via shortwave, 17860 kHz:

And from Discovery Channel Italia website:

The Golden Record attached to the Voyager spacecraft, transmitted as an MFSK32 image on 17860 kHz:

And from the NASA website:

The shortwave transmitter for all of the above is located in North Carolina.
