Hi Group,I have recorded signals from HGA22, DCF39 and DK7FC from two antenna/receivers at different locations. The locations are 58 km apart. Recordings are 16 bits, mono, 22050 Hz, and 1.5 hours long. The "space" signal from HGA22, (135430 Hz) is usually stronger than from DCF39 (138830 Hz). Is the a method that can use the signals of HGA22 (or DCF39) as a clock (reference) to look for the weak DK7FC signal in the recording? I am wondering if the two wave files could be synchronised in some way to and then added together to cancel out the noise and highlight the DK7FC signal frequency. Regards, Edgar Moonah, Tasmania. |
