From bmarx at bellsouth.net Wed Jul 7 11:51:48 2021 From: bmarx at bellsouth.net (Bill) Date: Wed, 7 Jul 2021 11:51:48 -0400 Subject: [QCWA Everglades Chapter #69] ARES info In-Reply-To: References: Message-ID: <9ddf178c-1a1c-a34c-a0bc-8ca5e090c8ee@bellsouth.net> From Marty Falk: Please share the following information with your members as you wish. I wanted to advise you that at this time the Northern Florida Section has activated the ARES Net on 3.950 Khz for Tropical Storm Elsa. NFL and WCF have members activated in various roles, so the NFL SEC requested the activation of the HF Net to provide any communications support that is needed. They are lining up stations for NCS duties, so if you want to fulfill that role, let net control know when you check in. Feel free to listen, check in when requested and assist net control if needed. Also, there is and has been an open net activated on SARNET most of the day and it continues at this time. There is a net control assigned and you should only participate if you have pertinent information to provide or are requested to provide information. Let me know if you have any questions or concerns. Thank you for all that you do for ARES and the community. Everyone please stay safe while this storm passes.
