Dave Johnson VE7VR, President of the Orca DX and Contest Club, showed a video titled VE7VR Hi Rise Remote during a recent Zoom call.
It details how he set up a HF station in his 14th floor condo and on the roof.

“In a new article published in Solar Physics, [a] research team predicts that Sunspot Cycle 25 will peak with a maximum sunspot number somewhere between approximately 210 and 260, which would put the new cycle in the company of the top few ever observed.” Laura Snider
Overlapping 22-year magnetic cycles will produce the ultra-strong 11-year magnetic cycle. 260 sunspots as a max! Amazing.
This is a very exciting article for HF radio operators. NCAR and UCAR news
HF communications are affected by sunspots. Their number is growing with the new solar cycle #25. There are eight classifications of sunspots. You will find them below.
The different classifications
- α – Alpha:
A unipolar sunspot group.
- β – Bèta:
A sunspot group that has a positive and a negative polarity (or bipolar) with a simple division between the polarities.
- γ – Gamma:
A complex region in which the positive and negative polarities are so irregularly distributed that they can’t be classified as a bipolar Sunspot group.
- β-γ – Bèta-Gamma:
A bipolar sunspot group but complex enough so that no line can be drawn between spots of opposite polarity.
- δ – Delta:
The umbrae of opposite polarity in a single penumbra.
- β-δ – Bèta-Delta:
A sunspot group with a general beta magnetic configuration but contains one (or more) delta sunspots.
- β-γ-δ – Bèta-Gamma-Delta:
A sunspot group with a beta-gamma magnetic configuration but contains one (or more) delta sunspots.
- γ-δ – Gamma-Delta
A sunspot group with a gamma magnetic configuration but contains one (or more) delta sunspots.

HF Bulletin #3
Hold onto your HF hats!
Dust off that ICOM, that Kenwood, that FLEX and those home brew CW rigs, it looks like good band conditions are about to surprise us all.
ARRL bulletin has a research paper predicting a very strong sunspot cycle 25.
Sept. 17, 2020 – Hello fellow WARA Members, As you know, our club meetings and functions have been suspended for several months now because of the COVID-19 pandemic. Recently, the Provincial health officials have further tightened the COVID protocols, closing ... Read more »
