The Princeton is particularly famous as the basis for Mesa Boogie's Mark I, which is a heavily hot-rodded Princeton equipped with modified preamp and a Bassman transformer, allowing it a higher gain output of 60 watts. Fender produced a solid state Princeton from 1988 to 2001, the Princeton Chorus.
The IIC+ is Mesa/Boogie's most valuable amp on the secondary market, with models often selling for over $15,000, as of 2023. [ 13 ] Throughout the decade, Mesa continued to produce combo and head amplifiers, and began production of rack power and pre-amps, developing power amplifiers such as the M180/190 and Strategy series, as well as pre-amps ...
Randall Smith began Mesa/Boogie with a practical joke: he borrowed a Fender Princeton (a small 12-watt amplifier) from his friend, Barry Melton of Country Joe and the Fish, and "hotrodded" it by replacing the amplifier section with a powerful Fender Bassman amp and installing a 12-inch speaker instead of the original 10-inch.
FSK441 employs multi-frequency shift keying using four tones, at a data rate of 441 baud. Because of the choice of character codes in the protocol, it is self-synchronizing and does not require an explicit synchronization tone. [6] FSK441 is generally used on the 2-meter and 70-centimeter amateur bands.
The Fender Princeton Reverb is a guitar amplifier combo, essentially a Princeton with built-in reverb and vibrato. The 12 Watt Blackface version was introduced in 1964 and available until 1967; in 1968 it was changed to the Silverface version with a drip edge around the grill cloth. Amps produced after the end of 1969 saw a change in circuitry ...
The conference maintained the 56–60 MHz allocation for other regions and allowed administrations in Europe latitude to allow amateurs to continue using 56–58.5 MHz. [3] In 1940, television channel 2 was reallocated to 60 MHz and TV channel 1 was moved to 50–56 MHz maintaining a gap for the 5-meter amateur band. When the US entered World ...
Encoder receiver transmitter (ERT) is a packet radio protocol developed by Itron for automatic meter reading. [1] The technology is used to transmit data from utility meters over a short range so a utility vehicle can collect meter data without a worker physically inspecting each meter. The ERT protocol was first described in U.S. patent ...
A wavemeter consists of an adjustable resonant circuit calibrated in frequency, with a meter or other means to measure the voltage or current in the circuit. When adjusted to resonance with the unknown frequency, the resonant circuit absorbs energy, which is indicated by a dip on the meter. Then the frequency can be read from the dial.
