AFAIK, the low modulation of RHC on 6000 has been that way for months now, at least for the English programming when I checked. I find some of RHC's cultural and music segments interesting, but I rarely even bother checking the broadcast anymore due to the issue.
Arnie passed away last year, and I suspect that had a big impact in RHC technical operations. I am not sure anyone left at RHC cares, or perhaps it could very well be more like there is not enough budget left to care.
