Editor's Corner

Hi, my name is Cale (K4HCK) and I'm the editor of Amateur Radio Weekly.

The most-clicked link from last week's newsletter was K3CAN's idea for an "Every Ham" Radio Contest. I would definitely participate should this become a reality even though contesting is not my jam.

ARDC is seeking qualified candidates to take on contract roles as a Software Developer and a Technical Writer. These are great opportunities to take on professional roles in the world of Amateur Radio.

Thanks to Yewknee for the shoutout on the blog. Yewknee is a cultural staple of Nashville focused on internet culture and music established long before the rest of the world moved here. (Also check out YK Records!)

Hamvention is only 5 weeks away and once again I'll be making the trip to Dayton. Zero Retries and DLARC have generously allowed me to use their booth as a meet-up spot for myself and any other Amateur Radio Weekly readers that wish to say hi. Reply to this email if you're planning to be at Hamvention. I'd like to hear from you. Also, stickers will be on-hand!
