Hi John and All,
Glad to hear that there is still some TA propagation. I will run DFCW tonight
using 30 sec dots. Dot freq. 135,921.5 dash freq.
135.922. I am very intrested to see wether this mode gets through, and would
appreciate any reports Start time 20:00utc
73s Laurie. G3AQC.
Hi Laurie
Hi Mike
I made a 30 dots ARGO-screenshot at 2319utc 06.03.01 (enclosed).
for better reading I
took the ARGO sensitivity down and got 12db between the antenna and the first
mixer of the receiver. the loads of the beginnings and endings of the dashes and
dots seen in the pic enclosed in my todays first e-mail - so far not from
FFT-processing - vanished. now ur line, Mike, is vy good readable.
the diff rx-input-voltage between ur signs is 10db +/-2db.
it is visible that the emission of Laurie has a "noise curtain" (as we do term
it in the german language) up to +/- 100 Hz.
