May I suggest a temporary alternate frequency for PSK31 while the Chinese jam 14070?
14092.0 kHz USB If past history of the Chinese Firedrake Jammer is any indication, we can look forward to many more days or months of jamming on 14070. They jammed 18160kHz (+/- 10kHz) for about a year before moving eventually to another frequency. 73 Bonnie VR2/KQ6XA
