Dear Stefan, LF Group,I guess from the traces on the grabbers that you must be QRT now - congratulations on opening up another new "band" at 6.5kHz! My program says the distance to DL4YHF is about 265km, so certainly out of the near field. Unfortunately, nothing was seen here that could be identified as a signal - the trouble is, with the spectrogram set for DFCW600, everything looks like a 600 second dash, like Peter was saying about modern art... The noise level this afternoon had risen several dB above the lowest levels at around 0800 - 1000utc, and being the middle of summer it is very noisy - so I am hopeful about detecting a signal in future tests. The QRN noise level at my QTH is about 2dB lower at 6.5kHz compared to 9kHz, but I would guess the increase in ERP at the higher frequency would be greater than that, so I would suggest 8.97kHz is a better frequency. Thanks for the test, looking forward to next time! Cheers, Jim Moritz 73 de M0BMU |
