The #YouTwin antenna rocks!

And it's back.

RT @IntlWspr: Permanent WSPR RX JW1ITS on Svalbard 10m Band reception crossing the circle - Airspy HF+ Discovery, Stampfl X One active dipo…

@lemielek Yes

@lemielek 3 x 3.33m = 10m wire.

@nmaster2042 All the updates go to the Ranger page.

@virendermvs This requires a realestate agent.

@virendermvs Why would I?

@PatrickPierre73 Bigger inductance.

@PatrickPierre73 I stacked two ferrite cores.

@NotToodday The best way to know is to try it.

@NotToodday I think anyone should be able to build it with scrap. If you use it with the HF+, you already paid for it!

RT @a_rlorenzo: NASA Astronaut Don Pettit (@astro_Pettit) on the ISS 🛰️ loud and clear over Spain as he talked to La Laupie Primary School…

@HB9VQQ At DC or low frequencies: The rod has higher inductance. At high frequencies: The difference in inductance between a rod and a thick-walled tube diminishes, but a thin-walled tube will have lower inductance.
