[Moon] Fw: [ZSVHF] Sporadic-E Opening on 13 December

Subject: [ZSVHF] Sporadic-E Opening on 13 December


> ZS1AGX reported what was almost certainly a brief Es opening Wednesday
> morning when the ZS5SIX beacon was heard near Cape Town from 0945 to 0954
> SAST reaching a maximum strength of S8. While a slim possibility exists of
> the propagation mode being tropo or even a series of several random
meteors,
> it was most likely Es. If that is the case, this opening is an extremely
> interesting one as the short 1200 km distance would indicate that
> frequencies as high as the 70 MHz band would have been supported. However,
> the midpoint of the path would have been around Graaf Reinet and one end
of
> any possible path would have been well out at sea off the southern coast.
> ZS5LEE in Durban was notified but no one in that area was available to get
> on the air. In the event that there is an Es opening please call on 50200
> USB or 51400 FM as well as the frequencies currently being monitored by
the
> digital group.
