Finland Radio Amateurs Seek Replacement Spectrum for 1240 – 1300 MHz 12/30/2020
Finnish International Amateur Radio Union (IARU) member-society
SRAL is asking for amateur radio privileges on 220 – 225 MHz as a replacement for the 1240 – 1300 MHz band, which was deleted last April 24, except for use by special permit. SRAL’s initial request for 902 – 928 MHz was turned down.
The request is to provide spectrum for Amateur Television (ATV) operation. The special permits for the 1.2 GHz band will expire when the Galileo GNSS (GPS) constellation becomes fully operational. Concerns have arisen in Europe regarding the potential of amateur radio interference to one Galileo frequency.

The K7RA Solar Update 12/11/2020
Tad Cook, K7RA, Seattle, reports: Solar activity quieted this week, with the average daily sunspot number declining from 57.6 to 28.9, and the average daily solar flux softening from 108.1 to 91.9. On December 8 – 10, the sunspot number was 11 on each day, which is the minimum non-zero sunspot number.
Sunspot group 2786 provided some great activity, but it is about to rotate off the sun’s visible surface. But a look at
STEREO satellite images on Thursday night (December 10) shows some magnetic complexity about to became geo-effective from the sun’s southern hemisphere. This could mean more great conditions.
The average daily planetary A index went from 6.4 to 4.4, and average daily middle latitude A index went from 5.6 to 3.1.
