Re: LF: carrier and others

[MarkusVester@aol.com]

Hello all,

 I had a directional spectrogram running during the day. The unidentified carrier came on abt 7:35 and disappeared abt 13:40, frequency drifting slightly between 137607.3 and 137610.1Hz. It was strong here, around 29dBuV/m (!) and coming in from 170° (SSE) +-5°.

SXV also came on with a carrier on 135.8kHz (DOA 135° = SE) at around 14:50, and turned on their traditional FSK since 17:20, which is much wider than the encrypted QPSK31 they were using last week.

This weekend, the old FM spurs around DLF (153k) have returned as well, with wideband splatters around 136kHz, having a variable spectral density on the order of 11dBuV/m per 100Hz here. Extrapolated to about 4kHz total bandwidth, this would be 0.3W transmitted EMRP or -59 dBc below their 250kW nighttime power.
