121.5 and 243

Guys,

can you help resolve an argument.

I believe I am right in saying distress calls on 121.5 will be picked up on 243 ( 2nd harmonic ?), what about the other way round.

Say a mil flight was crossing pond and put out a distress would a civilian flight hear -carrier only- carrier and voice - or nothing, (assuming they were only monitoring 121.5).

Do civilian flights only monitor 121.5.

The dispute was over the fact that a mil distress call was claimed to have been heard on a 121.5 only beacon
