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.
