Stefan,DK7FC and Christian,DF5QG
Last night I was looking for OH1AH on 472,5kHz but heard
only your signals on this qrg at about 23.00-24.00UTC
To be more precise I heard the keyklicks of your sigs which were
300Hz off on 472,2 .
Stefan's real signal was peaking true S9+20dB,so I guess he was not too far
away from
1W ERP [ within +/- 1Np tolerance :-) ] and Christian reached S9
while the key klicks of both of you were only 20dB down at 300Hz offset
which is S9 and ~S7.
My band noise was below S5 (100Hz BW) last night.
While both of you apparently have successfully worked on your ERP
I feel it is mandatory to work now on the signal quality by removing
the key clicks or at least reducing them to at least 50 or 60dB down.
Otherwise stations within a radius of say 400km cannot copy weak signals
when
particularly Stefan is transmitting with his tremendous signal a few 100Hz
away.
A clean signal is any ham's calling card anyway.
In the mean time it would be a good idea to stay away at least 2kHz from the
usual calling qrg 472,5 when you are rag chewing for hours which was
interesting to listen to.:-)
The band is wide and empty enough so there is plenty of room to choose.
To clear up some uncertainties about my antenna you have been discussing
last night
I have attached a picture from last year:-)
(Yellow is feeder,red is antenna).
