   Comments from Robert Nickels W9RAN,  July 27, 2023:There is nothing worse for a ham radio operator than to see a beloved friends callsign with the letters "SK" behind them.   Yet sadly, that's what happened on July 23, 2023, when I learned of the passsing of Merv Schweigert, K9FD.     While many of our ham radio interests were different - Merv was a...  READ MORE

   I know many of us who enjoy restoring and repairing vintage gear look forward to winter when there is less competition for time and energy, and a chance to really make a dent in our "to be fixed" piles.    A couple of years ago I set time aside for "Heathkit Singlebander Week" and went through every one of them I had, with the result that they're all working ...  READ MORE

   Most of the articles on this site are about hams, or  ham radio.   This one is not about a ham but about a man who built as much a reputation through HF radio as any ham on top of the BPL ever did.    Don Taylor is one of those rugged independent-minded people who thrive on a lifestyle most of us couldn't even imagine - as a trapper in Canada's Yukon wildernes...  READ MORE

   The microwave network constructed by AT&T Long Lines and other telecommunications companies in the past 50 years were engineering masterpieces using state-of-the-art technologies and some were designed to withstand nuclear attack during that Cold War era.     This is a non-hardened site on top of a mountain in upstate New York that existed long enough for graffiti taggers t...  READ MORE
