Dear Mike, LF group,

At 08:50 16/09/2002 +0100, you wrote:
What is Vlad sending? I am seeing a series of dashes close to the expected
frequency. Do you have an accurate frequency? It needs to be at least within
40Hz as QRSS3 software at the best sensitivity shows 80-100Hz on screen

I have been watching this frequency for the past several nights (except last night); there are plenty of Loran lines within a range of +/- 70Hz, some of which look like a regular series of dashes because they are actually two very closely spaced lines beating together. I have not seen anything that looks as if it could be a signal from Vlad, which is not so surprising considering the QRN level, which unfortunately seems to reach a maximum around midnight, which is when the signals from RU6LA seemed to peak - it blots out most of the Loran lines as well. I expect it should be possible to copy Vlad when conditions are a bit quieter, but it is a bit frustrating!
I am using DL4YHF's Spec Lab set for a span of +/- 100Hz around 136.1kHz,
which covers the possible range of frequencies with a margin for error -
with the waterfall expanded to full screen, and about 0.3Hz resolution, it
does not seem to miss anything.
I will be looking out again tonight.

Cheers, Jim Moritz
