Title: MC03 on 5139 kHz LSB, January, 2019
Post by: Token on January 13, 2019, 1729 UTC

Chinese military station MC03 has been active this month on 5139 kHz, LSB mode.

The transmitter is using a keyed audio tone in LSB mode, instead of ICW (keyed unmodulated carrier).  You can tell by the audio harmonics of the 500 Hz tone used.

Thanks for posting about this signal. I just tuned in via an SDR in Japan and it is going strong at that frequency, so strong in fact, that I had to turn my volume down in order to avoid a bit of distortion.
