Received my FLEX-6700 back after the PEN upgrade.  Started SmartSDR v1.3.8 & it stated that an update was required.  Did the upgrade. 

There is a intermittent buzzing noise that coincides with a jump of +10-20 dB in the panadapter and horizontal lines in the waterfall.

Help!  I am supposed to operate as W1AW/9 starting Tuesday.

v1.3.8.  But, problem may be external to radio.  After I posted, I thought to switch to a dummy load & it is normal on dummy load.  I just have never heard this type of noise across all bands before.
