Hi Roelof and group,
in my location - JO40LE - close to Mainflingen -DCF - I had to increase BW
for better rx-performence. The noise was caused by databursts from that
nearby commercial LF-TX. Narrow band and "good" shape-factor in the
IF-Filters meant tendency to ring. We are in the time-domain with it.
IF-filters with Gaussconfiguration prooved to be much more useful in this my
case.
Facit: the more steady the noise, the more narrow the BW can be choosen.
But yet, never seen any TA so far. We work on it.
Best regards,
Peter, dj9dw

Hello all,
Last night I tried ARGO.
The band started very noisy, but I got captures of WD2XKO and WD2XGJ.
VO1NA appeared later.
I have heard rumours that ARGO and SpecLab need some background noise to
compare the signals against and hence should work better with a (relative)
wider bandwidth.
At present, I am using a 12 Hz bandwidth and both programs seem to work
fine.
Can anyone shed some light on this?
Thank you in advance,
Roelof Bakker, pa0rdt
