The local HF-FAX service, Athens, suffered from bad transmission output (probably too much audio level in an SSB transmitter). See my older post. Nowadays all seems to work fine; the image quality is superb:
Both images logged yesterday morning on 8105 kHz USB mode with a +20dB signal. Athens also transmits on 4481 kHz (had an S9 signal). Usually the lowest frequency is better received at my QTH, but if ionosphere permits (relative) local propagation on higher frequencies, the 8 MHz transmission is better, with less multipath distortion (fuzziness of the lines).
