I saw very weak sigs tonight around 137700. Screenshort attached.
I will monitor freq from 137690 to 137750 next night (18-00 to 02-00 Z
24 Jan). Frequency resolution will be 0.13 Hz (best resolution permited by
my old computer). This means abt 8 sec FFT. Also averaging will be 6.
Total time of one pixel abt 24 sec. Please any beacon on QRSS60 or
QRSS120. QRSS30 also may will be seeing.
When change freq resolution from 0.5 Hz to 0.13 Hz I have impruve DCF39
reciption from 10 to abt 20 dB sig/noise at day time. Now (daytime) DCF39
is about 20 db over noise. Hope in night time it will be up to 50 db (best
S/N of DCF39 with 0.5 Hz was 40 or 45 db, usualy it was 30 db).
HPE CU VY SOON!
