By day, WGSO is powered at 600 watts, using a non-directional antenna. But 990 AM is a clear channel frequency so WGSO must reduce power at night to 310 watts to avoid interference to other stations.
In audio, 0 dBm often corresponds to approximately 0.775 volts, since 0.775 V dissipates 1 mW in a 600 Ω load. [16] The corresponding voltage level is 0 dBu, without the 600 Ω restriction. Conversely, for RF situations with a 50 Ω load, 0 dBm corresponds to approximately 0.224 volts, since 0.224 V dissipates 1 mW in a 50 Ω load.
A dBm is referenced to 600 ohms and is a power measurement. 0 dBm = 1mW across 600 ohms. (as defined by the I.E.E.E.) Combining Kirchoff's voltage law (V=IR)and the power formula (P=IV) you get: V = sqrt(PR); for a 600 ohm circuit, V = sqrt (0.001 * 600) = 0.7746 volts For a 50 ohm circuit, V = sqrt (0.001 * 50) = 0.2236 volts A dBu is not ...
By Nate Raymond (Reuters) -A U.S. appeals court has halted enforcement of an anti-money laundering law that requires corporate entities to disclose the identities of their real beneficial owners ...
The name twin lead is most often used to refer specifically to 300 Ω (Ohm) ribbon cable, the most common type, but on occasion, twin lead is used to refer to any type of parallel wire line. Parallel wire line is available with several different values of characteristic impedance such as twin lead ribbon cable (300 Ω ), window line (300 Ω ...
