“Antenna Work Weather” early this week!

Once you’ve done some mid-Winter repairs here are some local items of interest to pass the cooler and hopefully wetter weather which we’ll have late in the week.

DX Countries heard on PSK31 from EM15ff during last two weeks.

This is truly Radio Geek material – AM radio broadcast patterns!

The 2015 US and Canadian mediumwave broadcast pattern reference is now available for download. You’ll find the links on my web blog, RADIO-TIMETRAVELLER:

I’ve spent much of the last year working on mediumwave pattern mapping. The updated maps presented many challenges.

Note: you must be online to view the maps!

Download the two .zips (one is daytime, one nighttime), unzip them to a folder of your choice, and click on the frequency files. Daytime groundwave and nighttime skywave maps are included.

Maps are GoogleMap-based, HTML-driven maps showing the most current pattern plots of all licensed US and Canadian mediumwave broadcast stations from 530 – 1700 KHz. The set includes all frequencies for the indicated services: Unlimited, Daytime, Nighttime, and Critical Hours. Individual maps are grouped by channel frequency: 540, 550, 560 KHz, etc.

Data for the pattern plots in this offering is based on the current FCC and Industry Canada databases available at the time of its creation (January 22, 2015).

Hope you enjoy! Good DX!

Tornado Forecasting Workshop

OKLAHOMA CITY —The Storm Prediction Center and the University of Oklahoma’s Student Chapter of the American Meteorological Society has partnered to offer a tornado forecasting workshop series.

The severe weather workshop will be led by Storm Predictions Center lead forecaster Rich Thompson. Sessions will be held on Tuesdays starting at 7:30 p.m. at the National Weather Center, in Norman, Oklahoma.

Even though the workshop is open to the public, it will also be streamed live online for those who cannot attend in person.

Here is the current schedule:10952133_10153615041009922_2445331018014897428_n

  • Feb. 3, Sounding analysis and synoptic meteorology (lifted parcels, Q-G theory, etc.)
  • Feb. 10, Severe storm ingredients (low-level moisture and lapse rates)
  • Feb. 17, Severe storm ingredients (vertical shear and lift)
  • Mar. 3, Supercell and tornado conceptual models (plus composite parameters)
  • Mar. 10, Tornado patterns (synoptic and mesoscale)
  • Mar, 24, Convective mode forecasting (squall lines vs. discrete cells)
  • Apr. 7, Tornado parameter climatology (spatial and temporal distributions of CAPE and shear)
  • Apr. 14, Numerical models and statistical techniques (convective schemes and post processing)
  • Apr. 21, Real-time forecasting exercise

 Editor’s Note:

I would strongly suggest that if you have a good enough internet connection to be able to watch Youtube videos, that you stay at home and do so during these sessions. My personal expectation is that the curious general public will flock to the first session or two of this event thinking that it will be a succession of cool pictures and chase videos, but this will really be a layman’s deep-dive on the subject. While I do not expect he will discuss in-depth Quasi-Geostrophic theory in week one, I do believe that Rich will walk off into some deep water. That said, if you get the gist of RF propagation at HF frequencies, you’ll be able to follow his presentations. The link is here and will only be live when the event starts:
