Re: 1377 khz China
i have also monitored 1557 and 1206 kHz yesterday
1557 kHz Radio Taiwan was received
On 1206 kHz there were different weak signals, probably from the middle east, untill i rceived some Chinese voice, see video here https://youtu.be/S8Sqy_4cnug
It was identified from expert Chris Kadlec at the Dxing .info FB group as the Jiangsu Gushi Guangbo ( Jiangsu Story Radio ), a 10 kW station.
Not bad as a first approach to intercontinental Dx on MW with a small indoor loop. Unfortunatly i will not have the time to monitor constantly the MW during week days because i have to work to live :D
