Is there some carrier or coherent QRM present to generate these false hits? Just got a WSPR generating routine running on a 16F628 PIC with AD9852 DDS combination. At the moment it only operates at 100% duty cycle, but I'm Looking at PN sequences for randomised transmission slots with 20/25/33% Duty cycle operation. Andy G4JNT www.g4jnt.com
