KM4ACK 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 the story about the lawsuit claiming warrantless radio seizure from a child. Maybe not so coincidentally, after featuring the WSM Blaw-Knox transmitter tour last week, there were several more Blaw-Knox related stories published this week. The main story was about the future of the WBT transmitter site which features three Blaw-Knox towers. Not to be outdone, the WLW Blaw-Knox tower threw in its own suggestions. Happy Blaw-Knox week! This week I secured my tickets to Pacificon and the Zero Retries Digital Conference, both happening in the same general location on the same weekend in October. More details to come! General feedback regarding this newsletter or the content within is always welcome. Got a link to share? Simply hit reply. 73
