If this is not available then standard no.18 speaker wire will suffice With one end of the wire connected to the disk, begin winding a consistent coil around the rod. The coils should sit next to each other and be bound tightly to the rod.Any 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.Test the audio transmission and reception by speaking into one walkie talkie and listening for the audio on the other. Take the walkie talkies to different locations and assess the range of communication. Experimenting with different antennas can also enhance the range of the walkie talkies. 4. Ham Radio Receiver.Figures 10A and 10B show a coil designed to cover the 4-14 MHz shortwave bands, including international broadcasts and amateur radio. It requires heavier gauge wire (#16) and larger slits in the spiderweb coil. Because of the very wide tuning range, you may have difficulty tuning signals precisely. FIGURE 10. Template of spiderweb shortwave coil.Shortwave and HF Listening. In a truly grid-down situation where the radio is your only tool to find out what's going on in the world, the ability to listen to shortwave radio broadcasts and 2-way HF communication from hams or other radio operators could be a lifesaver, making an SDR receiver a prime source of intelligence.Get one here: https://amzn.to/36BfQtq Amazon Affiliate Store: https://www.amazon.com/shop/iridium242 Prep With My Patriot Supply: http://www.preparewithiridi...How the AM Radio Circuit Works. When the reactance (AC resistance) of capacitor C2 is the same as the reactance of the coil L1, resonance occurs at the frequency f=1/2π√ (LC). For example, with L1 equal to 300 uH and C2 equal to 100 pF: F = 1/2π√ ( (0.0003 H)* (0.000000000001 F)) = 919kHz. If they are in parallel (as in our circuit), the ...
