Danny, The lower end of 40m is the only place available for psk, and you are outnumbered by the number of countries that do operate there. 7070 is a busy phone calling frequency, 7075 is just as busy. No psk operation is possible. Why don't we all move above 7100 like you Americans? Good question. VK has has access to 7300, so why aren't we there? Sunrise, 6.00am, 1900z, 45 minutes ago. Strong AM broadcasters, in Russian on 7105, 7110, 7115, 7120, 7130, 7135, 7140, 7145, 7150 (with Radio New Zealand broadcasting a HUGE DRM signal there later on in the day, 7155, 7160, 7170, 7180, 7185, 7190, 7200 in Arabic, 7210, 7220, 7240 Radio Australia to the Pacific S9+40, 7255, 7270, 7275, 7280, 7295 (fat chance of HFLink) and 7300. The noise floor is very high, the signals overlap and the Chinese are banging away with an OTHR at the bottom of the band. The only segment that is mostly workable is between 7040-7100. In the evenings it is crammed with wall to wall JA's and Indonesians. Any QSO's are fortuitous. Care to make a sked mate? Brad VK2QQ
