Sad samo linkovi bez ikakvog opisa ?!? Kinder surprise? Clickbait?
A da napraviš playlistu na jubitou pa tamo dodaješ jedan po jedan?
Ovako si "izgurao" sve druge teme s popisa.

Pozdrav,
Slušao sam danas, ili bolje reći pokušao slušati ali sa dipolom za 3,5 ništa...
Ali zato postoji You Tube i evo snimke događaja.

Today we calebrating the 100th anniversary of the first commercial teleghram sent by the Alexander Grimeton station (sweden) SAQ
The main complex trasmitter site was built in the 1923, is now a UNESCO heritage site. It use the Alexanderson mechanical rotating transmitter working at frequency of 17.2 kHz in VLF band. The main works Is to controls the precise RPM speed of transmitter rotor to generate the exact frequency.
The antenna system has 6 tower of 123 meters height.

Zašto je važan balun (VF prigušnica) lijepo je objašnjeno u videu.
Lako provjerljivo tj. ''ne treba nikome vjerovati na riječ''  .

U drugom videu istog autora, G0KSC, objašnjeno je kako instalirati
prigušnicu napravljenu od koaksijalnog kabela (tzv. ugly choke).
