Not nearly so much to hear any more but you can still hear Numbers Stations and EAM type messages on HF. I got an SDRPlay RSP1A, which blows away all the dongles for just being able to hear and see wide swaths of bandwidth, but the most impressive radio if have played with in years is the Belka from Belarus .Here’s the clip for attaching the antenna to “something”. Most all portable shortwave radios will have a telescoping antenna as well as one that’s built inside (mainly for AM radio band reception). Some radios (usually the higher priced models) will have an external antenna jack, usually a 3.5mm (1/8″), where you can plug in your own ...

Buy the best and latest diy shortwave radio on banggood.com offer the quality diy shortwave radio on sale with worldwide free shipping. | ShoppingAny antenna that is less than 1/2 wavelength long and less than 1/2 wavelength high will start to loose efficiency when shortened or lowered. (1/4 wave verticals must also be at least 1/4 wavelength long and have an almost perfect ground plane). So for HF frequencies if you want to go a similar route you should look into magnetic loop antennas.

Setting up the 1886 loop is super easy. First, attach a length of coax to bottom of the amplifier box. (The 1886 uses SO-239 connectors.) Attach that coax to the top of the Bias Tee. The Bias Tee supplies power to the amplifier mounted on the loop using the coax and without introducing noise. Run another piece of coax from the bottom of the ...
