This mornings pass @2000 UTC orbit #28925 AO-51 was back to normal to my way 
of thinking USB up and FM down, no funny going carriers and signal strength 
was normal again I.E. S7 to 9, originally we down here thought the 
interference was caused by our northern neighbours as they cause a lot of 
havoc on AO-7 mode B as it goes South east to north west, thank you for 
every thing.
Alex VK5ALX with the MP3 recording showed it as we hear it.
As aside we here in VK/ZL look forward to AO-51 in mode V/S and each month, 
more are getting there gear up and running
