NVIS Antenna build presentation by W7CRG

At the February LCARC club meeting, Chuck Gertulla, W7CRG presented a very informative program on the merits and ease of building a “Near Vertical Incidence Skywave” or NVIS antenna. The complete build documentation, as provided by DX Engineering, using their kit, or as a reference to build your own, can be viewed here. Chuck’s handout and synopsis of NVIS operation can be found here.

Cascadia Coastal Community HAM Net

Coastal communities in the Pacific Northwest have a lot in common. In coastal Cascadia many people live in small towns or rural areas, which are often isolated by terrain and everyday radio / cellphone dead zones. Natural disasters don’t stop at jurisdictional boundaries. During times of disaster and service interruption, the usual transportation corridors to and from the coast may be cut off — the nearest help may be located in an adjacent coastal community.

The Cascadia Coastal Community Amateur Radio Net was established in to facilitate ongoing interaction between coastal groups (or agencies) interested in emergency or disaster-related communication. The purpose of the net is to share information and to facilitate communication between coastal communities in AK, WA, OR and CA in order to build community awareness, prepare for interruption of services and disasters, and to enhance overall community resiliency.

Net participants are those interested in sharing information on upcoming emergency or disaster-related training events and opportunities (posted to a calendar on www.cascadiacoastalcoalition.org), as well as, summaries of actual events. Starting in March 2025, the net will be run on the first and third Thursday of each month at 13:30 Pacific time on Brandmeister ‘Western Oregon’ TG 31412.

This is a directed net. Check-ins will share information with other net participants. The net is open to all licensed amateurs who have an interest in emergency or disaster-related communications especially those associated with ARES/ RACES, Hospital Communication groups, Medical Reserve Corps, Community Emergency Response Teams, and neighborhood groups.

Although there are a few DMR repeaters in our area of interest, most participants can use hotspots to access the DMR network. In addition to the net, the Western Oregon talk group 31412 may be used as an evaluator back-channel during large-scale training events (e.g., Disaster Airlift Response Team drills, Cascadia Rising, IronOR). If you need help with DMR let us know. We also have a few DMR radios and hotspots to loan out for folks to become familiar with DMR amateur radio.
