Sorry to be pedantic but M2 and Ch 80 are not the same M2 is UK only and is 161.425MHz and 80 is a Duplex Channel (Port Control) with the Ship transmitting on 157.025MHz and Shore Station transmitting on 161.625MHz and a standard International Channel. 80 shouldn't be in use for race control! only M2
Of course you are right, apologies for adding confusion, third week icebound so I am now posting on subjects I obviously know nothing about. I promise to exercise more self control. I am away to look for a thick book but not one on wireless telegraphy.
