This is also good for me in the Skip Zone of Nauen.
With MFSK32 text I have via backscatter significantly fewer problems 
than with MFSK-64.
But in the pictures there is no difference, either way: stray images

Was there last weekend a useful reception of KBC 7375 kHz in the US at 
all possible?
The MUF for the 1st  MaxHop (3000 km)  was significantly below 7 MHz, 
according Julisruh:

Last night this looked so much better.

With regard to the situation on 7395 kHz there were here no differences 
to 7375 kHz.
The signal was good and loud, but the sound was also backscatter-diffus.
Here is the change of CRI - KBC on 7395 kHz:
