This has the great advantage that current flows through two series capacitors from stationary plate, across the rotor to stationary plate without any sliding contacts. Wilson\u2019s capacitor was manufactured by <a href=\"https:\/\/www.bwantennas.com\/coilcat.html\">Barker and Williamson<\/a> and would have cost roughly $25 in the early 1930\u2019s, or nearly $500 in today\u2019s dollars. Wilson explained how this capacitor suppresses 2<sup>nd<\/sup>\u00a0harmonics.

Gas generator\u2019s work well, as long as there is gas.\u00a0 The recent events in the Key\u2019s illustrates that gas may be difficult to find and limited in supply. A dual fuel solution, or propane or natural gas may better if power outages are sustained beyond a few day, and one has access to a large propane tank, or existing natural gas line.<\/li>\n<li>Also, be sure to have cash on hand. If power outage is widespread, banks will be closed. However, during the day, restaurants may have ability to serve food, but may not accept credit cards, if power is out\u2026in this situation, cash is king.<\/li>\n<li>The <a href=\"https:\/\/www.redcross.org\/images\/MEDIA_CustomProductCatalog\/m4340160_Hurricane.pdf\">Red Cross Hurricane Safety Checklist<\/a> provides a good starting checklist to follow on hurricane preparedness.<\/li>\n<\/ul>\n<p><strong>Equifax Breach\u00a0<\/strong><\/p>\n<p>We had a very informative discussion on the recent Equifax breach. Dan (KR4UB) provided a document with links to the various credit rating bureaus.
