Right now (0740 UTC) the 11860 kHz transmission has no real carrier at all. 
It's a garden fence every 120 Hz, traceable between at least 11857 and 11862 
kHz and audibly appearing as buzzing sound. More dirty signals further away 
could come from this defective transmitter as well.

Times? 11860 is also R Marti and Cuban jamming, which can well expand beyond 
the times RM is really on air. Glenn

Also, Saudi's 9675 has been missing for at least a few weeks and the Saudi 
15170 quaran channel broadcast has been missing for 6 months or so.. but the 
15285 broadcast is still there

For the last few weeks I’ve heard a very loud buzzing on 11860, over yemens 
program audio. The transmitter is in Saudi Arabia.
I thought it was a transmitter fault the first few days but it’s still 
happening.
I was talking with a friend and we think it’s Iran jamming Yemen.
