As Andy, 8CPZ says this has been discussed several times - hopefully at some point the UK will get the WRC15 allocation (and keep the existing “bandlet” allocations as well). Until then, I have this label on my rig:
60m overlap WRC-UK - SOTA - suggestions
CW 5354.5 or 5362.5 KHz
DIG 5366-5366.5 KHz
SSB 5355 or 5363 KHz.
OR … Split.
73 Ed.
P.S. for US <-> WRC15 - I “think” Channel 3 is the only US 60m channel in the WRC15 60m band frequency range.
