Can you try to listen to 4885 kHz.?
Echo of Hope - VOH signs on there later than the other frequencies.
Normally on about 1155 UTC or so. Usually with nice clear "V O H"
IDs at 15 minutes after ToH.
Ever since they started to use 4885 kHz., back in Dec 2015, I have
always found 4885 kHz. unjammed and free of QRM, whereas their
other frequencies that sign on earlier are normally jammed (3985 //
6003 // 6250 // 6348).
Here is audio of one of my typical receptions -
