Whatever tendency the receptor has to howl with this arrangement can be overcome by putting in a grid leak of the right resistance and adjusting the condenser. The Parts and How to Connect Them Up.
To tune to different wave lengths you must have a wave-meter. The Use of the Aerial Switch. Where you intend to install both a transmitter and a receptor you will need a throwover switch, or aerial switch, as it is called. Aerial Switch for a Complete Sending and Receiving Set.
"The significance of the conditioned reflex is simply this, that an associated stimulus brings about a reaction; and this associated stimulus may be from any receptor organ of the body; and it may be formed of course not merely in the laboratory by specially devised experiments, but by association in the ordinary environment."
While I have suggested the use of the smallest size coils, you can get and use those wound for any wave length you want to receive and when those are connected with variometers and variable condensers, and with a proper aerial, you will have a highly efficient receptor that will work over all ranges of wave lengths.
"Output eighty-five thousand kilofranks," replied MacDonald, the first assistant. "Intake forty-nine thousand." "Not so good can't hold out forever at that rate. Shove out the receptor screens to the limit and drive 'em. They figure a top of sixty thousand, but we ought to pick up a little extra from that blaze out there. Drive 'em full out or up to sixty-five, whichever comes first.
With a long wave autodyne, or self-heterodyne receptor, as this type is called, and a two-step audio-frequency amplifier you can clearly hear many of the cableless stations of Europe and others that send out long waves. For receiving long wave stations, however, you must have a long aerial a single wire 200 or more feet in length will do and the higher it is the louder will be the signals.
In simple electric resonance an oscillating current of a given frequency flowing in a circuit having the proper inductance and capacitance may increase the voltage until it is several times greater than its normal value. Tuning the receptor circuits to the transmitter circuits are examples of sympathetic electric resonance.
This kind of a set is called a full wave rectification transmitter. The waves radiated by this transmitter can be received by either a crystal detector or a plain vacuum-tube detector but the heterodyne receptor will give you better results than either of the foregoing types. The Operation of Wireless Telephone Transmitters with Direct Current Short Distance Transmitter.
This is a better long wave receptor than the self heterodyne set described above for receiving wireless telegraph signals sent out by a continuous long wave transmitter.
Nedda's father's attorney watched with bland eyes. Hoddan said impatiently: "Let's get started so this will make some sense! I know what I've done. What monstrous crime am I charged with?" "The charges against you," said the justice politely, "are that on the night of Three Twenty-seven last, you, Bron Hoddan, entered the fenced-in grounds surrounding the Mid-Continent power receptor station.
