Geen Daily Minutes op maandag 26 maart 2018

Ik had wat hoofdpijn, en ik ben eind van de middag een half uurtje gaan slapen.  Dat half uurtje werd ongepland iets langer: 10 minuten voor zeven werd ik wakker.

Antennetuner uit de serie zelfbouw afl. 5 (25/3)

Resistance (or not feeling at “Ohm”)

Yet the history of Ham Radio is also one of resistance to change – not from the pioneers, they were often instigators of it, but from the “everyday” Hams.

Let me see if I can give you some examples, with my tongue planted very firmly in my cheek…

“That’s not Real Ham Radio!”

The early Hams used CW pretty much exclusively. So when AM arrived as one of the first of the voice modes, there was a bit of an uproar…“It’s not real Ham Radio! Real Ham Radio involves using a Morse Key! What in world is the hobby coming to, using voice to communicate over the airwaves? It’s sacrilege!”
