Re: LF: Slow BPSK Test (score: 1): Author: John Andrews <[email protected]>; Date: Mon, 20 Feb 2006 22:03:44 +0000; Tonight's WD2XES test will be a dead carrier on 137,577.309506014 Hz, interrupted only by CW ID's on the top and bottom of the hour. There will be no (intentional) phase changes at this end. The carr; /rsgb_lf_group-archives/html/rsgb_lf_group/2006-02/msg00127.html (10,575 bytes)

LF: Slow BPSK Test (score: 1): Author: John Andrews <[email protected]>; Date: Sun, 19 Feb 2006 19:29:09 +0000; WD2XES will try a run of slow BPSK on the following very odd frequency tonight: 137,577.309506014 Hz. This frequency appears to be clear of Loran lines for 1 Hz either side over a fairly large area,; /rsgb_lf_group-archives/html/rsgb_lf_group/2006-02/msg00144.html (11,266 bytes)

Re: LF: Slow BPSK Test (score: 1): Author: [email protected]; Date: Fri, 17 Feb 2006 18:49:02 EST; Hartmut, I believe such magnitude jumps are to be expected, due to the superposition of a phase-reversed signal from John and a constant-phase carrier from the Russian Loran.
