Bob,
looks like some dashes came through here around 3
UT, see 74 kHz grabber screenshots, or browse
df6nm.bplaced.net/LF/74kHz/
Warren,
meager traces appeared on your QRG around 23:30.
And then maybe for a short period after 5 UT - did you happen to
restart the TX again later?
On the TA grabs there occured two periods of
purple noise, 21:18 - 22:45 and 3:20 - 4:41. These are caused by
increased data throughput on DCF39. The FSK bursts are very
conspicuous on the DM4TR grabber
dm4tr.bplaced.net
which is located closer to DCF39. In the top panel,
you can see that there would be useful spectral gaps around 137.765 kHz
(about 10 Hz below the current TA slot), and around 137.63 kHz (70 Hz below the
QRSS-3 center). Note that the frequency scale in the second panel is
currently incorrect.
Best 73,
Markus
