The Sparton radio is a multi band set and the shortwave bands require a different antenna. I added a switch and some terminals to accommodate this need. The radio antenna is switched between the loop coupling coil, or an external antenna and ground. The other switch is a high low band switch and adds a 300 pf capacitor across the 365 pf ...For the specifics of winding your inductor, it is best to rearrange formula 1 to find the value of L for a given capacitor value and a given target frequency: L = ( 1 (2πf))2 C−1 (2) (2) L = ( 1 ( 2 π f)) 2 C − 1. So for your shortwave example, if your capacitor is set to 500 pF (500 x 10 -12 farads) and you wish to receive a frequency of ...

It is worth changing the loop size in the calculator to get the best efficiency possible in your favorite band. For example, my 30-10 Meter loop is 8.5 ft in circumference and 23% efficient at 10.1Mhz but 91% efficient at 28Mhz. This represents a difference of about 6dB or 1 S-Unit. The diameter of the conductor determines its resistance and ...I used the recommended tubes. For the audio-transformer - any 10k to the impedence of you choice will work - I used 3.2. I wound all of the coils by hand, except for the band 1 - for that I substituted a 70-osc that I got from antique radio supply. The last mod I did was to add a switch to add in about 400 or so pf to the tuning to shift the AM ...The main limitation of using a smartphone for shortwave radio reception is that the built-in radio receiver is typically designed for FM or AM broadcasts rather than shortwave frequencies.
