Puyallup, WA Ultralight TP's for 10-10

Thursday, October 11 2018



Hi Chris,

Gary's answer is quite correct, and similar boosts occur around
sunset when the receiver is to the east of a transmitter on the other
side of the ocean. Japanese DXers have heard Argentina on 1030
around Japanese sunset for example, and I'm sure Mark Connelly and
others can relate large amounts of DX heard in the eastern USA and
Canada in that situation.

Some of the enhancement is due to lower levels of domestic
interference as the encroaching sun knocks it out (or domestics are
still in daylight in the "eastern" instance), so there is a better
signal to interference ratio, but some of it, and in some instances,
much of it, seems to be due to an actual increase in signal strength of the DX.

best wishes,

Nick

at 250kw, but I think you don't get TP at those hours anyway. >>>

You would probably laugh if you could see the very brief period that
the Korean signals build up in strength during our local sunrise
enhancement period, then crash down to nothing soon after they hit
their peak. In the case of both 603-Hwaseong and 657-Pyongyang the
first hints of an audio signal appear around 1100 UTC here on most
nights (0400 local time) in October, but they usually are very weak
and trivial (typically staying near carrier level) until local
daybreak. Depending on whether the propagation is good, bad or ugly,
the daybreak boost can either shoot them up to an S9 level within 15
minutes, or something weaker, or nothing at all. In any case, if you
have a sudden S9 signal from Korea (with the exception of maybe
972-HLCA or 1566-HLAZ) you can be sure that the signal is going to
nosedive within a half hour, so you better have your recorder ready.
During exceptional sessions (especially on ocean beaches) both 603
and 657 can stay in strong audio for over an hour
after daybreak, although here in this mediocre location you would
be lucky to get 20 minutes.

As you know, Hawaii is in a completely different propagation league,
and even the Seoul metropolitan jammers can stick around for hours
starting at 0800 UTC in December.

came out the very month I moved to Korea.
