Shortly before the first day of February 2008, I switched off my usual station PSU and connected in its place a homebrew battery made from four bleach-filled cells. Power output was around 3mW on the usual 7,000,850 +/- 50Hz, and the shack smelt like my toilet when it's just been cleaned. The batteries powered the beacon for about a week, peaking at over 6mW; but after 5 days the power level dropped below 1mW and no further reports were received from my very poor antenna. |

Thanks for all reports! The following reports are in reverse chronological order (most recent first):
05-Feb-08: 7,000,850 1.5mW BLEACH power!

The last known copy of my bleach powered beacon signal was from Les G3VYZ at 14:00 |
04-Feb-08: 7,000,850 3mW BLEACH power!

Weak but identifiable by Peter PA1SDB at nearly the same time, 13:40 |
02-Feb-08: 7,000,850 3mW BLEACH power!

Les G3VYZ saw Peter DL6NL and my signal together at 10:00 |

Around the same time, Pierre ON5SL also saw Peter and me together, at about 10:18 in JO10TT |

Together with Peter again, seen by Pierre ON5SL at 11:43 |

Les G3VYZ saw me with Martijn PA3GFE at 11:47. I am about 15Hz higher than Martijn. |

At 14:25 Giovanni IZ1JKO captured all three signals in Italy (JN44JS). From top to bottom: Hans G0UPL, Peter DL6NL and Martijn PA3GFE! |

Peter PA1SDB again at 15:31, but Peter faded out |
01-Feb-08: 7,000,850 3mW BLEACH power!

Les G3VYZ was the first to copy my beacon on bleach power at 10:36, in IO95FB! Possible reasons for the frequency instability include 1) bubbles in the bleach causing voltage variation and 2) temperature variation due to me sitting next to the transmitter. |

Pierre ON5SL copied my signal at 12:26 in JO10TT |

My signal pops up briefly with John GM0RZY, 13:42 |
