Thank you Stefan.

I look forward to seeing your results.  Its quite amazing how just a slight increase in S/N can make a huge difference sometimes.

These are exciting times for MF and LF..

73!

Out of curiosity, are most stations in Europe  using directional RX antennas or only omnidirectional/TX antenna?  Most of us here state side that have made it across at one time or another using WSPR or other modes are using directional antennas.  Just a matter of curiosity on my part.

As far as i know, most stations arround EU are using omnidirectional antennas. Maybe 10% are using loops or cardioid antennas? I know F6CNI and F1AFJ are using cardioid antennas.
On my RX location in the city i'm using a small active omnidirectional E field antenna. On my remote RX site i'm preferring a loop beaming NW/SE. In some time i will have finished my stereo receiver for MF. The i can decide to use a T-antenna or a loop or a combination out of these two antennas resulting in a cardioid system. The advantage over e.g. a K9AY design is that i can use the configurations simultaneously, i.e. i can build (in SpecLab) a cardioid antenna beaming to NW AND a cardioid antenna beaming to SW AND an omnidirectional antenna, receiving to the same time :-)
