    The type 36 screen-grid tube (obsolete since the mid-1930s) had a non-regenerative detection gain (audio frequency plate voltage divided by radio frequency input voltage) of only 9.2 at 7.2 MHz, but in a regenerative detector, had detection gain as high as 7,900 at critical regeneration (non-oscillating) and as high as 15,800 with regeneration ...

    As a result, manufacturers often specify devices as being either pin-to-pin or drop-in compatible. [2] Pin-compatible devices are generally produced to allow upgrading within a single product line , to allow end-of-life devices to be replaced with newer equivalents, or to compete with the equivalent products of other manufacturers.

    A crystal set receiver consisting of an antenna, a variable inductor, a cat's whisker, and a filter capacitor. A crystal receiver is very simple and can be easy to make or even improvise, for example, the foxhole radio. However, the crystal radio needs a strong RF signal and a long antenna to operate.
