The SLSRC Program for May is “Show and Tell” about what you have been making, some new projects, or a new mode of ham radio you are using, etc.

Also, did you go to Dayton this year...or even in previous years?  What were the highlights of the trip....did you purchase any new “toys”?  If so, tell us about it at the May meeting.

So we have an idea of how many will be “Showing and Telling”, please contact Rebecca KC9CIJ at This email address is being protected from spambots. You need JavaScript enabled to view it., so you can be put on the agenda.

Looking forward to seeing everyone on May 27th at the meeting.

The April presentation will be all about the Raspberry Pi.  The Raspberry Pi was introduced in February 2012 as a teaching tool to help teach computer science in schools and developing countries.  Since it's inception, there have been 4 major versions, the latest Pi 3 was released in February 2016.

The Pi is a fully functioning computer, complete with a processor, RAM, video, ethernet and I/O pins.  Not only did the education community grasp the Pi by storm, so did the hobbyist community with their pet projects and specialized applications.  Today, there are hundreds of uses for the Pi, everything from running as a Linux server to home automation and SDR applications.  

Kyle will give some information about the current Pi, demonstrate how to setup a Pi from scratch, and also have some guests show off what they have done with their Pi in the amateur radio community.

Last Fall (October 2015), Viktar had a chance to visit Hartford, CT, and tour two places of definite interest to radio amateurs both full of historic and educational "stuff", and equipped with ham radio stations open to visitor operation.  One site is very well known to everyone, the ARRL Headquarters and W1AW.  The other is the Vintage Radio and Communications Museum of Connecticut and its station W1VCM, run and maintained by a local group of enthusiasts.  Viktar will share some of his pictures and highlights of both attractions, as well as some travel tips not to miss when planning a similar trip.
