The Constitution of a "Good Set"

RECEIVER of merit should possess sensitivity, selectivity and a really good tone, by which is meant clarity as well as rotundity. Volume is really a fourth consideration, because once a set has been turned up to give tone power, in one of the many possible ways, can be increased. Sensitivity is a factor that counts, for this means range. It can be secured by seeing that rectification is as near perfeet as possible, by using judicious reaction, and, sometimes, by increasing the plate potential of the detector and H.F. valves. TE LT

Ue Selectivity is a matter that concerns the aerial system and the tuning gear, and often exerts an influence on tone because an ultra-selective circuit is always working on a tuning "peak," to over-run which, or to almost but not quite reach which, will utterly ruin signal quality. Rotundity is a matter determined by judicious low-frequency amplification and the use of :uitable reservoir qondensers across the output. ) The happy operator is he who takes such pains in his experimenting as to strike a convenient medium in all things, and this can only be done by devoting time and patience in tuning up the whole circuit so that it ultimately provides. the result desired.
