With the solar flux rising again in the winter of 2014/15 I’ve finally got my Raspberry Pi microcontroller based WSPR beacon on the air. I’m generating RF on 160m, 80m, 40m, 30m at night and 20m, 17m, 15m, 12m and 10m during the day every 2 minutes using my club call sign KW4VA. The controller generates ~10 milliwatts of power to either a 40m horizontal full wave loop in my attic up ~25′ or ZS6BKW @ 50′ or 400+’ long wire in the back yard. I’d developed a script awhile back to pull data from WSPRnet and display who has been copying my 10mw signal. Below you will see a Google map on which I plot of the most distant stations who have received my signal over the last few months. The red 0 icon is my beacon location at the intersections of all the lines. The other blue icon #’s are placed over the 6 digit grid square or approximate latitude and longitude of the receiving station. Those blue # icons represent what band (in meters) my signal was received. Click on the icons to read more information about the receiving stations to include their call sign, grid, distance, beam heading, average signal to noise ratio, # of reports posted, frequency and first and last times I was spotted. The color of the lines represent received signal-to-noise ratios (SNR) in dB [red <-20, -20 < yellow <-10, green >-10]. Click on the View Larger Map links below this map to see a larger interactive map with more specific band data for my running total of unique DX country spots.
