Hi Laurie, It seems that 30 second dots is so superior to 3 sec dots
it comes through despite cmes . I thought I saw M0BMU at 2315. I
had "O" copy on G3AQC and M0BMU at 0212.
The German station at 128.9 was S-3 up until
i saw it at S-5 at 0230. By 0246 QRM from 60 Hz wiped me out
It is obvious that dfcw is far superior
when it comes to speed of information transfer. I will be sending picture
later
There appears to be a third station
just below G3AQC. He is lower by about 1.5 times the difference
between Laurie's dots and dashes
I'll be looking from 2100 thru 0000Z
tonight and agn for short period at 0400
I figure 30 sec dots is 10 db better than
3sec dots and from a reliability standpoint this also seems to be
true. Condx like last night would never Have produced readable sigs
with 3 sec dots. I reckon With good condx 100 to 200 milliwatt stations
could get across . The reception of G3XDV proves this

Hi
all.I was transmitting 30sec
dot DFCW from 20:00 until 07:00 last night, on 135,922 +/-. I saw G3XDV
above me on 135.923,but have no idea where the interleaving signal comes
from.Looks like propagation
still in trouble from CMEs, will try again tonight. 73s Laurie.
