Canceled events and sources of information

Updated Friday March 27, 2020

Canceled WCARES and related events

Due to concerns over the potential risk of Coronavirus Disease (COVID-19) infection spread by group gatherings, our EC, Ed Hudgens, WB4RHQ has made the decision to cancel the March 21st monthly meeting.

Self-isolation is currently considered a best-practice for reducing the risk of infection and may be key in slowing the virus so as not to overwhelm our medical infrastructure.

This may be a good time to stay in touch with each other using our local repeater system. If anyone becomes ill and needs groceries or other items dropped off at your doorstep, please reach out. We’re all in this together.

Please also note that the informal weekly Chew & Chat has been canceled until further notice and that the Hamvention Executive Committee has decided to cancel Hamvention for 2020.

How do antenna tuners work?

Dave, KI4PSR gave the Technical talk at the February Monthly Meeting with the first in a series of presentations on antenna tuners.

In this first installment Dave covered the basics of antenna tuners and dispelled some myths (a tuner does not improve the radiation efficieny of the antenna.) An overview of reactance concepts, reactive matching and an introduction to L-network tuner configurations were next followed up with a brief demonstration.

Dave says this presentation was inspired by the work of Davide, IZ2UUF
