Flex1500 475,2 kHz tx signal en VK9XSP

1V t/t    FLEX1500 XVTX/C signal
Below 480.601 kHz   on the edge of 1Hz the XVTX  signal  changes from sinus to a complex wave form
It would be nice if Flex would change the firmware to tx on 471- 479 kHz 
but Flex is  not so flexible


475kHz filter 


475kHz  after simple IF filter

       



VK9XSP   Polish Dxpedition  to Christmas Island   heard on 160m with workable signal but they have a receiving problem on this band.
VK9XSP   7,021kHz real 599 but they did not copy me
