To those interested
CFH today 110100
This morning at 0900 S7 then it either switched off or disappeared until
I hrd it agn at 1530 about S5 and now at 1843 utc barely audible and it
is dark. The theory about daylight/night time propogation is flawed on
LF as observed at this qth.
I get the same propogation from CFH and the Greek rtty day and night but
there are some fluctiations which are attributed to absorption by the D
layer whether it be day or night. I also have heard OH1TN and IK5ZPV
stronger during daylight hours than night time.
With any propogation depending on D, E or F1 F2 there will be big
variations because of unstable ionization of the layers day or night.
Observations from others could be useful on long haul signal reception.
