Going back to the days of wavelength and crystal conrol, "the 135" was 2226kHz. Very well used by fishermen for intership. There were other intership channels which fishing vessels used but in Scotland they almost always monitored 2226Khz (and seldom 2182) - so much so that 2226kHz was a frequency installed at Wick Radio GKR where, prior to making any Mayday Relay broadcast, procedure was to make an announcement on 2226KHz advising vessels to tune to 2182 for the broadcast.
