W4HM Daily HF-MF Radio Wave Propagation Forecast #2019-112

Happy Easter to all of my Christian friends around the globe.
 
If you are not a Christian you can join the faith. My favorite Christian web page is http://www.intouch.org .
 
The Christian faith is the only one that makes it clear as to how to get to Heaven:

John 3:16

For God so
loved the world, that He gave his only begotten Son, that whosoever believes in
him should not perish, but have everlasting life.
 
 
 
Greetings to
my fellow hamateur radio and SWL radio enthusiasts around the
world.
 
Welcome to my
now shortened “not for profit” W4HM Daily HF-MF Radio Wave Propagation
Forecast.
 
It’s the only
accurate daily global HF-MF radio wave propagation forecast produced on the
planet.
 
You can sign
up for the daily email delivered global HF-MF radio wave propagation forecast
at
 
 
You can view
the forecast online at
 
 
 
I’m a
heliophysicist, troposphere meteorologist/climatologist, physical oceanographer
and one of the few on the planet with advanced education and forecast experience
in all aforementioned disciplines. In troposphere weather forecasting I have 46
years of experience and in solar, space and geomagnetic weather forecasting 31
years In physical oceanography 10 years.

(((((W4HM
Solar Cycle 24 Update and Solar Cycle 25 Forecast- Short and to the
point.
 
Solar minimum
will begin later in 2019 and may last longer than any previous solar cycle in
the 20th century. When solar cycle 25 finally gets underway it could be the
weakest since the middle of the 19th century. Another “Dalton” type lesser grand
solar minimum may occur with a corresponding cooling of earth’s climate.
 
This would
negate anthropogenic climate change (harmful man induced global warming) if it
were occurring, WHICH IT ISN’T.
 
For more
“truth” on the left wing lie of anthropogenic climate change (harmful man
induced global warming) check out

On February 1,
2008 I forecasted that solar cycle 24 would be the smallest solar cycle in the
past 100 years. That forecast verified. I also forecasted that solar cycle 25
would be almost non nonexistent

This HF-MF
Radio wave propagation forecast is produced based on the SIGINT_CAP HF-MF radio
wave propagation prediction software. X and O ray tracing is
included.
I wrote it
beginning in the late 1980’s but I’m sorry to say that it still can’t be
distributed to the general public. It does outperform VOA CAP and Prop
Lab.
I do check the
actual band conditions at my location in the USA and tweak the forecast manually
where and when necessary.
 
I also check
global HF-MF radio wave propagation conditions via remoted radio
receivers on
every continent of the globe and tweak the forecast manually if
and when
necessary.
 
And last but
not least I look at ionsonde stations on every continent of the
globe.
 
The hamateur
radio JT65A mode RF signal levels received are based on 5 watts
and ½ wave
dipole up at 40 feet.
 
The hamateur
radio PSK31 mode RF signal levels received are based on 25
watts and ½
wave dipole up at 40 feet.
 
The hamateur
radio CW mode RF signal levels received are based on 50 watts
and ½ wave
dipole up at 40 feet.
 
The hamateur
radio SSB RF mode signal levels received are based on 100 watts
and ½ wave
dipole up at 40 feet.
 
The HF
shortwave broadcast band AM Mode RF signal levels are based on
100,000 watts
(100 kw) and a typical high gain VOA type curtain array
antenna.
 
The MF
broadcast band AM Mode RF signal levels are based on 50,000 watts (50 kw) and an
omnidirectional vertical antenna.
 
Please keep in
mind that this is a relatively simplified HF-MF radio wave
propagation
forecast, so as to keep it easily understandable and applicable
by the average
radio enthusiast.
