HF Radio Conditions and "Short Skip" Prospects -- Awesomely Current!

If you click on this image (not current), it will take you to a current
ionosonde for Boulder, Colorado, which likely covers much of western
North America at that latitude. You don't have to understand the graph itself.
At the bottom left is a row of data indicating what the MUF is for various
distances away from you. So for example, if the MUF for 100 miles is 6.5 MHz,
you will probably not be able to do short-skip (NVIS etc.) for 7.2 MHz. Also
look (upper left) for the foF2 frequency in MHz, that is truly the
NVIS cutoff freq. AGAIN: click on the image to get the current info.

 

 


 

 

HAMCLOCK -- Amazing Tool for HF Propagation Conditions (VOACAP etc) and Satellite Tracking

 

WB0OEY Hamclock website here

 

This app is better than all the other HF-related tools on my page here. The app runs on a Raspberry
Pi 3B or Pi4 (that I've tested) and from what the author says, it may run on a PC under Ubuntu 18.04
and even a Mac. The map can be toggled between 'globe' (like here) or a Mercator map.

foF2: F2-Layer Critical Frequency Map
The map below is a real-time image.
It shows the maximum radio frequency that can be reflected by the
F2-region of the ionosphere at vertical incidence (that is, when
the signal is transmitted straight up into the ionosphere). This
definitely shows why, many days, short-skip on e.g. 40 meters is
just not possible. (See the ionosonde diagram at the top of this
website for more F2 info.)

1. Kodiak also broadcasts weather forecasts during time slots initially allocated to Adak.

2. Routine weather forecasts are broadcast four times per day with these being the normal times when repeats of Notices to Mariners are broadcast in lieu of weather. Weather warnings may be broadcast at any time.

The U.S. Coast Guard may on occasion have to defer or shorten the broadcast of a scheduled weather forecast via NAVTEX to ensure delivery of more urgent navigational and safety warnings.

NAVTEX receivers must be programmed with proper NAVTEX station and subject identifiers in order to receive weather broadcasts.

It is intended that all NAVTEX weather be broadcast with subject indicator "B", for Meteorological Warnings, which cannot be rejected by the NAVTEX receiver, or "E" for routine forecasts. However, this cannot be fully implemented at the present time within the U.S. Therefore, all mariners in U.S. waters should program their NAVTEX receivers to include subject indicator "E" in order to receive both warnings and routine weather forecasts via NAVTEX.

Effective April 22, 2008 U.S. NAVTEX broadcasts of weather forecasts containing a warning or a Dense Fog Advisory will be broadcast with a Subject Indicator of "B" vs. "E", such that receipt cannot be suppressed on the user's equipment. Mariners are encouraged to include subject indicator "E" in programming their NAVTEX in order to receive routine weather forecasts as well as weather warnings via NAVTEX.
