This circuit shows an active antenna that can be used for AM, FM, and shortwave (SW). On the shortwave band this active antenna is comparable to a 20 to 30 foot wire antenna. This circuit is designed ...

Short-wave listeners often are not able to, or allowed to, install a long-wire antenna or other large dimension antenna in or around the home. In such cases, the present active antenna, intended for ...

The circuit presented here illustrates the fact that in spite of all kinds of new component and technology, it is still possible to design useful, and interesting, circuits. The circuit is based on ...

【Improve Reception】Use AN-03 short-wave external antenna to effectively enhance the reception of FM and SW signals of the radio (including the adapter cable). 【Antenna Size】The longest tensile length ...

There are all kinds of shortwave radio stations in the world, but WBCQ seems unique. Allan Weiner at the foot of the rotatable antenna installed in 2018. Located in Monticello, Maine, WBCQ is an up-to ...

GPS can be a bit complex of a technology – you have to receive a signal below the noise floor, do quite a bit of math that relies on the theory of relativity, and, adding insult to injury, you also ...
