📻BPF-Protection-against-Out of band signals on 40 Meters📻

📻Chinese broadcast stopper. Also, stops MW & LW broadcasting CRAP on the 40-meter band.📻 The Chinese government broadcast system seems slightly disrespectful to international frequency usage. They are not alone. However, they are by far the most prolific breakers of international agreements pertaining to radio. I maintain that nobody is the proprietor of frequencies. Yet, so far we have managed. In an age of internet, there is no excuse for this abuse. 📻Note the values chosen are due to reality. In this mode of reality, the values are mostly due to needed value and some are due to availability of component. When in total doubt, we must resort to the use of preset variable capacitors, which must be set up with a spectrum analyser or if you ain't got one, then use a bench signal generator and an oscilloscope. 📻Yank Side people will note that the 40-meter band in the EU ends at 7.2 MHz whereas Trump Side, this will end at 7.3 MHz. 📻FYI: Yank side persons should probably not use this circuit, or if they do, then take some time to understand it (if possible) and then (in between trying to dominate the world and building mental walls around a stolen land where the indigenous were murdered in their beds) try to get your tiny minds around this simple circuit. 💀@LentiFuckShit, don't bother trying to understand this, or anything really. Indeed, just fuck yourself off. Note::: Summary of LentiFuck's status: 🐖, 🍺, radio-rental (London slang for mental person or other derogatory remark about the sanity of a person)
