On 3 November 1906 the Berlin International Wireless Telegraphy Convention agreement established 500kc/s as the maritime calling and distress frequency and SOS as the distress signal. To mark this centenary the Radio Officers' Association will be on air using the callsign GB500KCS on 3-4 November. QSL via operator's instructions. This special event will form the launch of the Radio Officers' Association campaign for 500 kHz to be recognised internationally as a 'heritage' frequency.

CQWW is this weekend.

The solar news is not brilliant, although there have been a number of sunspots over the past few days... (It peaked at 50, but is back down to zero now)

The predicted planetary A index for Friday through Monday, October 27-30, is 10, 20, 10 and 5. Geophysical Institute Prague calls for unsettled conditions today, October 27, unsettled to active on October 28, quiet to unsettled on October 29-30, and back to quiet conditions for October 31 through November 2. Also, on Thursday October 26, the sunspot number was back to 0. Don't be surprised if we see no sunspots through the weekend and beyond
