PA0O ham radio

I might need some other receiving techniques. Last night  WD2XSH/6  EM31js  was received strong  by G8HUH  IO81MG I was hopping all night 510.000 kHz   for WE2XGR/6     and  499.600 kHz  for WD2XSH/17  (USB dial setting)  ( +160 and 80) But  WD2XSH/6  was on  495.983 kHz  that means I had to set my dial 1500 lower  to 494.500 kHz  to receive him And possible  WD2XSH/17  did move here too?? I would like to receive  them all ... Now i have WSPR set 600= 499.600    other = 510.000 To have more hopping frequencies  some not used bands like   7 or 14 MHz  could be set to other 500Khz bands.. This is my short list of  current WSPR 500kHz bands: Dial:      502.400      used in EU   Dial:      ...
