A second test of the Silvertone at my parents house (larger garden, fields on 2 sides) showed at least 10 stations could be received loud and clear without external antenna with more coming in with a short wire antenna, no buzzing at all in this location.
My conclusion:
Nice compact and thermally efficient short superhet set, -best suited for rural areas /low tech households. Needs a conventional iron step down transformer to 110v
How much power does your MW stations transmit at?
In the US, the stations transmit at anywhere from 500 to 50KW, depending on the location. At night, the stronger ones reduce the power and change the antenna orientation to alter the signal pattern.
