HAARP WSPR 80m transmissions July 30 – Aug 1

(Source: Southgate ARC)

Chris Fallen KL3WX will be using 80 kilowatts into the massive HAARP antenna array in Alaska for WSPR experiments in the 80m band from July 30 to August 1

Chris KL3WX tweeted:

WSPR experiments are tentatively planned to occur between 2300 and 2400 hours UTC on July 30, 31, and Aug 1. Most broadcasts will be at the 80m dial frequency default in WSJT, that is 3.5926 MHz with AM (3 dB loss) because HAARP does not have an upper side band (USB) mode yet!

Like a few of us contributors here on the SWLing Post, Robert Gulley (AK3Q), writes features for The Spectrum Monitor magazine (TSM).  Robert and I are both passionate supports of TSM–for a mere $24 per year, you get a monthly digital magazine that is simply chock-full of articles covering all aspects of our radio hobby. A phenomenal value indeed!

I’ve just discovered that Robert has published a number of his past TSM articles–reviews and how-tos–on his excellent blog All Things Radio.  Each article can be downloaded as a PDF. Here are the topics:

Video: Lightbulb vs Radio Beacon by Thomas Cholakov (N1SPY)

Many thanks to SWLing Post contributor, Ivan Cholakov (NO2CW), who writes:

My 11 year old son Tommy (N1SPY) completed a project where he compared a 1W lightbulb to a .25 W radio beacon that he put together and bet that the radio beacon can be heard around the world. I asked him to document his activities as he went along. The project took a couple of months but is now complete and we stitched together a video of his activities.

Wow–Tommy, you’ve done an amazing job here!

I especially like how you’ve taken time to explain the principles behind the various steps of the process. Brilliant job!

Tommy, your future videos are always welcome here. Keep up the good work and we’d love to hear how many new countries you’ve racked up on your WSPR system!
