Clear Frequencies Requested for Net Providing 24/7 Coverage of Saint Vincent Volcanic Eruption
3.185 MHz LSB and 7.188 MHz LSB
The Caribbean Emergency and Weather Net (CEWN) has been providing round-the-clock coverage during the La Soufriere volcanic eruption on the island of Saint Vincent and the Grenadines. Several neighboring islands are also being affected by the disaster. When responding to disasters and emergencies such as this, the CEWN utilizes 3.185 MHz LSB and 7.188 MHz LSB. CEWN is requesting that radio amateurs not involved in the volcano response to keep these frequencies clear.
WARA is testing holding our Saturday Morning Coffee Breaks by using the Zoom platform. This will be very informal in place of the breakfasts that we can’t hold right now. The first Zoom meetup was very well received, and there was a sense that the group wanted it to continue.
Saturday Zoom meetings provide a chance to say “Hello”, meet and put faces to people we only hear on air, swap stories, and have a “Show and Tell” if you have a new piece of kit you want to brag about.
All members should have received an email with the login information. I hope to see you next Saturday morning, March 20th at 10:00AM, PST
Brent Besse VA7BNB, WARA President
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.
