Last week's 136kHz DX

Another busy week (incuding a visit to the London 2012 Paralympics) has prevented daily posts. Here is a summary of my LF activity:

4-5 September: Transmitted Opera32 overnight. Thirteen stations in nine countries (GW, G, LA, RA, SM, F, TF, PA, DL) reported my signals.
DX included: RA3YO (2315km), SM2DJK (1780km), TF3HZ (1858km) and RN3AGC (2483km).
VO1NA was received by F5WK, GW0EZY and DF2JP. Unfortunately, I missed an announcement that he was to be on a non-standard frequency for Opera32 - 137.777kHz - so I did not receive him.

5-6 September: A single transmission of Opera32 produced reports from seven stations in six countries. Best DX was TF3HZ (1858km), RV3APM (2470km) and RX3QFM (2681km).
Others getting DX reports were: RA3YO received by G4WGT (2416km); DF6NM received by TF3HZ (2552km ), RD4HU (2713km) and RX3QFM (1991km); PA0A received by RX3QFM (2219km).

7-8 September: A single early Op32 beacon transmission was reported by G4WGT, F4DTL, PA0LCE, G8HUH and F5WK. I was on receive during the night and decoded the following (best reports in brackets): G8HUH (13dB signal / noise ratio), DF2JP (-24), DF6NM (-24), RN3AGC (four decodes between 1933 and 2233 with best S/N -34dB).

9-10 September: Transmitted Opera32 overnight. Eight stations in five countries reported my signals.
DX included: RX3DHR (2584km), TF3HZ (1858km), RN3AGC (2484km), SM2DJK (1781km) and RN7T (2837km).

10-11 September: Received overnight Op32 from: G8HUH (-19dB S/N), RN3AGC (-36) and DF2JP (-32dB).

11-12 September: I transmitted Opera32 from 2015 to 0815UTC. Eight stations in six countries reported my signals. DX included: RX3DHR (2584km, best S/N -34dB), TF3HZ (1858km, -25dB), RV3APM (2470km, -28dB) and SM2DJK (1781km, -27dB). Interestingly, where several reports were received, the best one was close to dawn at the Eastern end of the path.
QRO station DK7FC, also transmitting Op32, got a -37dB report from W1VD.

Op32 3-4 September 2012

My Opera32 transmission  last night produced reports from 13 stations in 8 countries with 4 stations over 2000km. Conditions seemed better to the east than the west

Best DX was:

SM2DJK, a new station for me, one decode at 2040UTC, S/N -33dB, distance 1780km.

TF3HZ, 8 decodes between 2146 and 0500UTC, best S/N -35dB, distance 1858km.

RN3AGC, 7 decodes between 2251 and 0248UTC, best S/N -32dB, distance 2483km.

RX3DHR, 4 decodes between 0110 and 0248UTC, best S/N -30dB, distance 2582km.

RX3QFM, 9 decodes between 2007 and 0110UTC, with a best signal / noise ratio of -32dB and a distance of 2681km.

R7NT, one decode at 2251UTC, S/N -36dB, distance 2835km.

Good DX from other stations included:

VO1NA was received by DK7FC.

UA4WPF was receied by UA0SNV-1.

Good LF Conditions

I ran another Opera32 test transmission overnight (2-3 Sep). I received some good reports and others did well, too.

My test was reported on by 14 stations in 7 countries: GW0EZY, DF2JP, LA4ANA (a new station for me), G4WGT, G8HUH, F5WK, R7NT (another new one), M0PPP, G4MDH, F6CNI, RN3AGC, F4DTL, TF3HZ and G0TKN.

Reports over 1000km were: LA4ANA at 1102km, 2 decodes at up to -33dB S/N between 1951 and 2045UTC; TF3HZ at 1858km, 11 decodes at up to -33dB S/N between 2304 and 0432UTC; RN3AGC at 2483km, 9 decodes up to -33dB S/N between 2045 and 0221UTC, and R7NT at 2853km, 8 decodes at up to -36dB S/N between 2045 and 0221UTC. A later, offline report was received from RN3AUS (2441km) whose best decode was -36dB.

Other stations making distances over 1500km were: PA0A received by RN3AGC and RX3QFM; UA4WPF received by UA0SNV-1 (2889km); DF6NM received by RN3AGC, RD4HU, TF3HZ and RX3QFM; and G8HUH received by TF3HZ.

Interestingly, the usual propagation indcator, Dst, was fairly high then crashed during the night. See this graph from the Colorada space weather centre:
