Domenico,
the QRP carrier is not visible here. The attached spectrum shows a stored peak from a short 100 W carrier around 20:40 (green). The yellow trace is the latest spectrum from approx. 21:30 to 22 UT. The noise is about 20 dB below the old peak, and the QRP signal must be less than that. Are you sure that 10 W are delivered to the antenna?
Best 73,
Markus

Yes, Markus
carrier is on now till next trasmission. Von: Markus Vester <[email protected]> An: rsgb_lf_group <[email protected]> Verschickt: Fr, 23 Okt 2015 11:41 pm Betreff: Re: LF: Coherent BPSK on LF using EbNaut Domenico, nil from the 10 Watt transmission at 21:00 UT, only noise.
Could you perhaps leave the carrier on during the pause, to let me check signal level and frequency?
73, Markus

Markus, thank you for the report. The small difference in QRG is due probably to the fact that i'm not using resample now. Transmission of 6 char./3s with 10 W will start in few seconds. GL Domenico / iz7slz On 10/23/2015 10:51 PM, Markus Vester wrote:
