Just widely separated dashes of about 8 seconds length... QRU----- Original Message ----- From: "Andy Talbot" <[email protected]>To: <[email protected]> Sent: Friday, February 20, 2009 5:11 PM Subject: LF: WSPR SpotsAccording to the WSPR Spot database, there is some "interesting" DX being received chez GM4ISM. 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.
