Small D-Class Audio amplifier board.Let's design a decent longwire antenna for general shortwave listening. We will want to listen down to 2500 kHz (2.5 MHz), then analyze its performance. The formula for determining the ½ wave length of wire is: 468 ÷ f (MHz) = feet. In our example, 2.5 MHz is our lowest frequency, therefore: 468 ÷ 2.5 = 187.2 feet of wire.August 21, 2021. 3851.

rtc February 7, 2020 at 11:04 am. Two ways to think about this: If you intend fixed operation then go with your converter. Just about any portable will work well since LW will be converted up to HF. If you prefer portable operation then the best way forward imo is to get a PK Loop. It will greatly improve reception on any portable you use whether fixed or portable,you can null out the noise too.Description: It can be used to DIY shortwave radio and telescopic antenna element.
