WSPR spots while using dummy load

QRP-LABS U3 1Watt into dummy load
Having destroyed the BS170 FET in my QRP LABS U3 I decided to press a small driver amp I'd made into service instead of replacing it.  Wasn't sure what power out I would get and was pleasantly surprised with the easy 1 Watt it produced driven directly by the  Si5351A synthesiser.  The driver was running in class A so no easy way to turn the power out down but nevertheless I decided to soak test and left the U3 running into a dummy load for several hours.  Really don't know why I decided to check WSPRnet for spots and was amazed when several came back.  As you can see in the photo nothing was screened. Perhaps there is a warning there for the next time I start whistling into a dummy load
The spots I received

Pskreporter and DX

Don't you just love PSKreporter, tells you all the DX you've missed while your out and about. Here's what my radio received today on Six. Best of the bunch A6VQ TY2AC AB1NJ. Oh well, most likely wouldn't have worked them anyway.
