Hi Ken
See attached Winlab screen shot of a group of alpha
stations, shown as little white dashes on the upper window. They
start just below 12 kHz. Spectrum lab shows more clearly where they are
located, but the real time shot on Winrad gives a better idea.
I suffer from interference from the 25kv East Coast Main LIne railway just a 100
yards or so from my aerial at Biggleswade. The antenna is a PA0RDT
miniwhip, see also top right of the picture where it is mounted on a
pole.

Hello All.
Were there any Alpha Stations transmitting on
9.941 at 13.30 UTC?, I was checking to see I my Stefan 2 - 24 kHz preamp was
working using Winrad and saw a small peak 9.941 about 15dB above the
noise, disconnected the amp and definately coming down the antenna. Not sure
how large a signals I should see from Stefan's pre amp when switched on the
noise level does not change any suggestions please.
