Not that I know of.

On your initial post you mentioned having a signal ranging from -1 to +1 into the UHD sink.  You may want to back that off to at least 1/2 that amplitude as something may be overflowing.

Maybe post your GRC file.

For example, if I set my signal so that it initializes to a sine wave with peak to peak amplitude of 1V, after turning the carrier on and off it might end up having a pk-pk amplitude of 0.5V or 0.2V or 0.8V.
