Dear LF Group,

Thanks for the reports overnight on the 136kHz beacon transmissions - It has 
been a while since previous T/A beacon activity from M0BMU, so it is good to 
see that the signal is getting out. The beacon was shut down at 0712utc - I 
have to lower the antenna to its normal height before daylight so the 
neighbors don't see it!

For information, transmitter power is about 900W from a modified "Decca" PA. 
The antenna is a 60m span of wire, which is normally 10m or so high on 
average; last night the centre of the span was raised to 16m, making the 
average height about 13.5m. Antenna current was 4A. Based on measurements on 
similar antennas in the past, I estimate ERP to have been about 0.7W.

Cheers, Jim Moritz
