11430kHz AM 2020-07-19 00:01z interval signal, ID then numbers. Gone at 00:20z recheck
18040kHz 2020-07-19 transmitter is apparently defective with carrier on and off every second or so. During interval signal the flutes can be heard each second and bits of numbers are sometimes audible (in usb, lsb and am ) also. I saw this last night too but didn't realize what it was.
