A strong start, then suddenly the signal got weaker until about 0827. From that point I logged 99.5% CDA.

Hi Zyg and all,

Today was not perfect, but from 0827 until the end I logged >99% CDA. The weak result at the beginning was perhaps because I forgot to switch off the LED lamp power supply this morning which generates QRM around 9 MHz. The SNR peaked at 23.0 dB around 1045 UTC.

On this side of the pond the morning's reception, apart from the normal QRM during the last half hour, was pretty much perfect - 87.80% audio decoded, 21.03 dB max SNR. My Ten-Tec RX320D receiver does not show SNR higher than about 22 dB (it's an AGC thing I think).
