This may be of help to everyone?
"For me, it has always been fun trying to tie down if a station heard is really a Sound of Hope reception or just the CNR-1 program jamming.
Here are a few suggestions, based on my years of observations:
1) One positive way is to listen at the top-of-the-hour. CNR-1 programming always has time pips, while SOH never has any.
2) Find a known CNR-1 frequency, that is to say a non-jamming frequency (I use 6125 kHz.), then check to find if it is // to
the station in question.
3) SOH is a religious station, so has a more refined format. At ToH usually has news and then a lot of monologues. Rather
rare to hear music. While the CNR-1 format is fairly contemporary; many short segments; often with music; in general has
a much more upbeat format than SOH.
4) After many years of listening to SOH, I find their audio slightly muffled; not a lot, just enough to be noticeable, especially
when compared to the crisp audio of CNR-1.
5) It is not uncommon for SOH to be slightly off-frequency; while CNR-1 is on the exact frequency (xx.00).
6) Finally, if the station in question has fair to good reception, it almost certainly is CNR-1 jamming. SOH stations use rather
low power, hence fair-good reception would be extremely rare.
7) If you are fortunate enough to actually hear SOH, their top-of-the-hour ID is "Xiwang zhi sheng guoji guangbo diantai"
(Sound of Hope international broadcast station), given twice (once by OM and once by YL), then into the news."
