Short-wave radio is split into broadcasting seasons. Traditionally, there are two major seasons, Winter and Summer, with two smaller ones centred on each vernal equinox. We DX'ers love the variable conditions an equinox can bring but to a Transmission Planner, a nightmare.
All the stations try to get frequency allocations in all the bands so they can move to lower frequencies in Winter in a desperate attempt to be heard in the target country. Conditions during the compilation of the HF Guide have been so unreliable as to warrant mid-season changes. Like those for Derby County, they have had limited success.
Our receiver is an AR7030 based in the English Midlands, so forgive a European bias in these archive listings
Station names are subject to change without notice.
Here in the UK, we have traditionally used Greenwich Mean Time. Around the world, this is referred to as Universal Time Co-ordinated or UTC, sometimes quoted on-air as just "UT".
UTC is the same as GMT that is one hour behind BST. QED.
