An overview of the radio observations during June 2018 is given.
The graphs show both the daily totals (Figure 1) and the hourly numbers (Figure 2) of “all” reflections counted automatically, and of manually counted “overdense” reflections, overdense reflections longer than 10 seconds and longer than 1 minute, as observed here at Kampenhout (BE) on the frequency of our VVS-beacon (49.99 MHz) during June 2018.
The automatic counts were sometimes very difficult due to strong (local) interference, thunderstorms (especially on 7.6.2018) and on 17 days by sometimes strong sporadic E.
Most automatic counting errors were corrected manually, sometimes by comparing with observations on 49.97 MHz (BRAMS beacon at Dourbes) or, in a few selected cases, by interpolation.
The hourly numbers, for echoes shorter than 1 minute, are weighted averages derived from:
N(h) = n(h-1)/4 + n(h)/2 + n(h+1)/4
