Conditions are unlikely to improve significantly in the foreseeable future and will inevitably deteriorate further as summer approached. In these circumstances PARC cannot hear any stations from most of the UK and it is virtually impossible to operate our 'usual' exciting programme - sadly it's all beyond our control.
HF Propagation - 40m doldrums
Propagation on 40m took a big hit on 1 March with a Coronal Hole affecting radio conditions by depressing the daily average Critical Frequency (foF2 0900-1700 UTC) to barely 5.2MHz. Since then, the Maximum Usable Frequency has only occasionally reached 6.3MHz which just permits UK-wide contacts on the 40m band. More coronal holes have occurred since then and have tended to depress the daily critical frequency even further making UK contacts on the 40m band very difficult or impossible most days.
