ARLP043 Propagation de K7RA
 
Solar activity increased this week. The average daily sunspot number went
from 197.4 to 193.4.

 
Predicted solar flux is 265 on November 8, 260 on November 9, 250 on November
10-11, 245 on November 12-13, 240 on November 14 and 165 on November 15.

 
Activity on 10-meters has been fantastic. There is no want of contacts using
CW, SSB, or FT8. Radio operators can quickly fill up their logs with QSOs
made on this band. And don't forget 6-meters.

 
Send your tips, reports, observations, questions, and comments to
k7ra@arrl.net [ mailto:k7ra@arrl.net ] . When reporting observations, don't
forget to tell us which mode you were operating.
