Joe,
 
the 0.1 Hz spaced sidebands were probably not caused by the TX, but related to the RX noise blanker being periodically triggered by DCF39 bursts. They were probably just being smeared out when the TX started to behave strange. Looks like the antenna output could be disturbing the DDS clock line?

Hi Henny, 

 

That's interesting.  The first half shows sidebands which disappear 

and the sigs then become fuzzy.  Terry saw fuzz on them yesterday. 

Last night, there was much fuzz seen on the G4WGT and DF6NM grabbers 

until I returned  the xfmr between the 4427 driver and the Decca. 

Strange! RF getting in the DDS?
