Hi, My name is John, I remember when I was 10 years old I built a one tube radio using a 1t4 tube, my recollection of the power was with a 1.5 volt battery and a 9 volt battery.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.TA7642 IC. Additionally, this TA7642 is significant for low voltage portable Radios. It is accessible in the package of UTC7642 is TO-92. Thus, the featuring highlights of this IC have a low ‎operating voltage, a very nominal input voltage (Vcc) which is around 1.3V, and a low Quiescent Current ICCO ‎which is 0.2mA and requires a few other ...Amazon Affiliate Store: https://www.amazon.com/shop/iridium242 Prep With My Patriot Supply: http://www.preparewithiridium.comThrive Life Freeze Dried Food St...
