Hi Markus,

Thanks again for the observations. Maybe you are right. Anyway i think i want to wait until the S/N is 3 dB better, or 6 dB. IF you are right, then we will get easy copy with a cardioid receive antenna!
Probably we will start to build the loop within the next days...

This looks like another possible detection of DK7FC at YV7MAE:
 
12-05-14 2:13 - 2:34 "D" and "K".
 
Dots appeared on 136172.82, and a dash on 136172.90 Hz. Notably the frequenciy offset is the same as last time, actually 0.14 Hz low. Please note that this time I have scaled the insert horizontally but not vertically, so the FSK shift appears smaller there.

This morning I noticed a few suspicious dashes in the noise of the YV7MAE Eu-capture. Comparing to Stefan's signal as seen here, we find that the activity displayed on 136171.82 possibly matches the first two dots of an "F", the last of a "C", perhaps the middle of a "D" and also the middle of following "K". Of course at this SNR this may be just coincidence or wishful thinking, and the frequency readout would be 0.2 Hz low. A couple of dB more SNR needed...
