Solar Cycle 25 has officially begun. Amateur's rejoice!

Hopefully not to long before we start to see some sunspots and propagation again!

"September 15, 2020 - The solar minimum between Solar Cycle 24 and 25 - the period when the sun is least active - happened in December 2019, when the 13-month smoothed sunspot number fell to 1.8, according to the Solar Cycle 25 Prediction Panel, co-chaired by NOAA and NASA. We are now in Solar Cycle 25 with peak sunspot activity expected in 2025, the panel said.

Solar Cycle 24 was average in length, at 11 years, and had the 4th-smallest intensity since regular record keeping began with Solar Cycle 1 in 1755. It was also the weakest cycle in 100 years. Solar maximum occurred in April 2014 with sunspots peaking at 114 for the solar cycle, well below average, which is 179.

Solar Cycle 24’s progression was unusual. The Sun’s Northern Hemisphere led the sunspot cycle, peaking over two years ahead of the Southern Hemisphere sunspot peak. This resulted in solar maximum having fewer sunspots than if the two hemispheres were in phase"

Making Contacts and Testing the Icom IC-705 on HF (7 MHz)

15 September, 2020 - Reading time: ~1 minute

Just a short video with some contacts made with my Icom IC-705 on 40 metres (7 MHz).

I was only using the internal battery and the antenna was a half wave end fed wire only a few feet off the ground.

Soon I'll be upgrading the antenna to allow working on 80m and getting it much higher, but not bad for a first run. You'll even notice a bit of DX from some US stations.

WSJT-X Setup on the Icom IC-705

9 September, 2020 - Reading time: ~1 minute

The Icom IC-705 has not been added to the official list of radios supported by WSJT-X. In this video however, I will show you how you can set the radio up to work with WSJT-X and perhaps other digital modes.

As of the date of this video, the latest version of WSJT-X is v2.2.2.


Future releases will no doubt support the IC-705 and when that occurs you will not need to change the CI-V address as per this video however all other settings will still be relevant.
