CLE 213 Results



As usual, the wonderful LF and MF conditions experienced during the week went into the dumper as the CLE weekend arrived.




Looking back, most of this can be blamed on our monthly (~28 days) repetitive schedule which nicely matches the rotation of the Sun. It seems that the same large coronal hole stream that whacked us during CLE 212, is the same one that showed up for CLE 213 right on schedule. Perhaps we need to shift our schedule by a week in case it wants to hang around for yet another rotation.

Conditions were not as bleak as I make them sound but they were a far cry from those enjoyed earlier in the week. The skip seemed fairly long on all three nights, but most signals were on the runty side, with only a few making strong appearances here on the left coast.

As shown below, conditions were quite 'flat' for the entire weekend and propagation did not vary much in quality other than favoring slightly different regions each night. Interestingly, 'YLH - 247' in Landsdowne House, Ontario, whose antenna was pictured on my last blog, was not heard at all on both Friday or Saturday but had a booming signal on Sunday night.

My usual procedure with the Perseus SDR is to record the CLE segments of the band for two minutes, every hour and every half-hour, from shortly after sunset to local sunrise. It then requires several hours of carefully going through the recordings to see what CLE signals were recorded ... sometimes spending up to an hour on one frequency only, sorting out what was coming through.

I have also found that the classic blue-screen waterfall does not yield the best contrast for finding weak signals ... the 'photo-negative' screen shown above is far superior, with signals in black appearing on a white background.
