With thunderstorms and lightning dotting the weather map across North America, a few enterprising and devoted operators were making reports last night for the 630-meter stalwarts (Note: I was one of the stations cowering in the face of storms and lightning so I disconnected and got a good nights sleep!)
Noise Warrior Andy, KU4XR, reported using a small loop stick in the shack and achieved 125 spots overnight. Not bad at all. Here is a query from the WSPR database showing unique call signs from the overnight session:
From Indiana, Ken, SWLK9EN61, had a similar idea and reported a whopping 368 spots over night and the unique sampling is below:
The design on both of these is simple: a variable cap in parallel with an inductor tuned to resonance.
If you ever think you can’t, think again. You just have to decide to make it happen and innovate. Congrats to these guys for keeping the reports flowing!
