That claim was made by Finnish Rear Admiral Heimo Iivonen, who reported this to the JAIC. He is/was also head of the Finnish Coastguard, so I doubt very much he was being less than honest about this.
Betcha he didn't report anything of the kind.
Here's the section of the JAIC report discussing rescue operations, including radio transmissions:

Much mention is made of Channel 16 in this chapter, including transcripts of extensive distress traffic recorded by several stations on that channel. No mention is made at all of any jamming on that channel, or even any significant interference of any kind.
And I can't find a mention anywhere in the report of Admiral Iivonen, who was actually a JAIC commissioner, reporting anything at all about Russian jamming of channel 16 or any other frequency of interest.
