Icom America

Will Jourdain AA4WJ

For the love of Ham Radio.  This motto has been at the heart of Icom’s philosophy ever since our first Amateur transceiver rolled off of the assembly lines back in 1964.  To this day, Amateur Radio remains one of Icom’s largest divisions as we remain committed to the hobby that we love through continued technological innovation in our product line. Digital voice technologies like D-STAR and powerful new software-defined radios like the IC-7300 and IC-7610 have expanded new horizons for enthusiasts all over the world.

Will Jourdain, AA4WJ, is one such enthusiast, having been licensed for almost twelve years.  He has been a member of the Icom family, working as a sales representative for Amateur Radio products, for over three of those years.  Born in Dalton, Ga and now living in Atlanta, some of Will’s earliest memories involve being around radios as his father, also a ham, introduced him to the world of RF communications.  Will now spends much of his time sharing his passion with fellow Amateur Radio operators as a spokesman for Icom products.

We hope that you will join Will in the Icom booth at Hamfest Chattanooga and Tennessee State D-STAR Convention. Whether you have questions about Icom products or just want to share your own passion for our marvelous hobby, we look forward to seeing you soon!

YL Forum

Catherine Andrews AC4YL

Melanie Glemser AG4YL

Catherine Andrews AC4YL
Catherine was first licensed as KK4UBQ back in September 2013, upgraded to General Class License in April 2014, then upgraded to Amateur Extra Class license in December 2016 taking KW4PE before acquiring the vanity callsign AC4YL.  Believe it or not, a British TV mini-series called “Wish Me Luck” about underground wireless operators (including women) during WWII in France is what sparked her interest in amateur radio

She founded the YL Op Net back in October 2014 and this net is still active on the Echolink ALARA Conference every Thursday evening at 8pm Eastern year round.  The purpose of the net is to encourage YLs everywhere to become and stay active in amateur radio, enhance our operating knowledge and skills, share ham radio experiences, and have fun!

She enjoys contesting, activating parks for WWFF/KFF (before that had a blast activating parks for NPOTA with Melanie AG4YL back in 2016), encouraging other YLs to participate and have fun in amateur radio, doing YL forums at major hamfests in the Southeast with Melanie AG4YL, “chasing paper”, and exploring the many aspects of this wonderful hobby.

Melanie Glemser AG4YL
Licensed in 2014, Melanie enjoys contesting, portable operations, chasing DX and learning new ways to “play radio”.

She started participating in the YL Op net soon after she was licensed to find out if there was a place for her, being a YL, in amateur radio.  The answer?  Yes, there is!  It was finding that answer for herself that really inspired her to help other YLs find their own place in amateur radio.

“Having been fortunate to have some wonderful Elmers and Elmiras (YL Elmers), I wanted to give back to the hobby and help others, especially YLs, who often don’t have that built-in system of mentoring that the OMs do.”

Please join them for a look into YLs in Amateur Radio.  OM (Old Men) are welcome to participate in these forums…who knows you might learn a thing or two.  🙂
