Ham Radio Crash Course Editor's CornerHi, my name is Cale (K4HCK) and I'm the editor of Amateur Radio Weekly. The most-clicked link from last week's newsletter was Graywolf, a new software based APRS client with a graphical web UI. Time to add this one to my list to experiment with. I currently run an igate using Direwolf, so I'm curious to see how the other wolf compares. Hamvention is here! Don't forget about the Fediverse meet-up later today at 11:00 AM at booth 1506 in building 1. I've been live-posting as much as I can on my Mastodon account if you'd like to see plenty of photos and forums from Hamvention and Four Days in May. Need more Amateur Radio news?
