Hey All,

8 Sep 21 0210 UTC 640 KC:

CMLA /Radio Progresso Cuba -poor to fair in QSB/ slight Co channel QRM, slight  beat note,  QRN lightning at 100 mi.


One of my favorite Dx targets.

Played Guantanamera and other vocal songs.

Straight audio ( no processing) from recently acquired Trans Oceanic / Select-A-Tenna.

First audible copy of the season.

Dust off the headphones boys, AM season seems to be on the way.

Hey Don,

This one has always been a puzzle .

Supposedly "10" Kw and "at" Las Tunas. I have gone back to this Cuban frequency  for years, it is the most "dependable" (which still doesn't mean COMMON).

 I have heard of supposed "sweet" ionospheric distances where a certain region is within a dependable coverage due to a "correct" geometry of transmitter vs receiver. "Maybe". But at only TEN Kw ?

Hmmmmm.

I am not sure if the published info about ANY of the Cuban nets (Progesso, Rebelde, Reloj ) is 1000% accurate.  640  in Cuba is certainly a Progresso network station. I have heard ID's a zillion times. The location to me is somewhat irrelevant and it "MAY" not actually be in Las Tunas. Whatev.

I have more of problem with the alleged power  level. Is 10 Kw really going to do SO "well" year after year, even with a good salt water  path and  possibly  being at a    "sweet" distance ? Again , Hmmmm.

All other Caribbean MW Dx  here seemed to "require" a LOT more horse power than 10 Kw.

Just going with it though,
