The best image resulted from a resolution bandwidth optimized to the short pixel duration and fast scanning with no averaging (1.4 Hz, 250 ms). In the PaintShop "postprocessing", I simply blanked the noise-only intervals before compressing horizontally, so the maximum SNR for a given transmitted energy should be recovered. A 29 kB gif file describing this procedure can be sent directly. Thank you Andy for this interesting experiment. Does the _BCN mean beacon? vy 73 de Markus DF6NM, JN59NK ________________________________________________________ Markus Vester wrote: Hi Andy, just a quick response: yes, hell clearly is there, abt -5 dBuV/m now, but hardly readable. I can easily see the vertical lines chirping downward, but the horizontal dots are difficult. I tried several spectrogram settings, 0.7 Hz / 500 ms seemed best for SNR (see gif). Averaging would probaby be better in connecting the parts of a character, but it smears out the dots so they get lost in the noise. The signal can't be everywhere at the same time. Theoretically, one would wish for a sliding bandpass synchronous to the chirps, which would block the noise in between. I will experiment with more settings on the recorded wav files later. I'll try to call you in DFCW, and maybe you could also send narrower bandwidth hell. 73 de Markus --------------070306030907000203020007 Content-Type: image/gif; name="HELL_JNT.GIF"
