27.760 MHz MFSK Data Stream 10 kHz Bandwidth [With Audio + Waterfall Video Link]
« on: March 15, 2024, 1431 UTC »
Via G8JNJ SDR. 

Two distinct data signals - center frequency is 27760 kHz 27.76 MHz, lower side data signal is centered at approx. 27.757 MHz or 27.758 MHz and the high side data signal is centered at approx. 27.762 MHz or 27.763 MHz. 

Overall bandwidth is almost exactly 10 kHz...looks like its closer to 9.5 kHz.
