A superheterodyne receiver is a Radio Frequency receiver method that multiplies the received signal frequency with a local oscillator frequency to get frequencies that are the sum and difference of the 2 frequencies. For example, if the received signal is 5MHz and the local oscillator frequency is 4MHz, they are multiplied together. 1MHz and 9MHz frequencies would be gotten. Usually the 1MHz is the Intermediate Frequency (IF). It will be admitted (through a band pass filter) later passed through the required electronic circuits for proper processing. There is also the method of the Variable Tuned Filter.

What device was introduced commercially in 1934 as a portable super regenerative receiver and transmitter?
The device introduced commercially in 1934 as a portable super regenerative receiver and transmitter was the "Radio Telephone," specifically developed by the American company RCA (Radio Corporation of America). It was designed for use in aviation and other mobile applications, allowing for more flexible communication options. This innovation marked a significant advancement in radio technology, paving the way for modern portable communication devices.
How do you add a remote transmitter to a Pi codex 2-ch receiver?
On Receiver: Open receiver There is a Jumper called Learn Short for 1 second. (Use jumper or Screwdriver) Remove jumper/screwdriver led on receiver switches on. On Remote/Transmitter: Press the button required for that receiver. Led goes off on receiver after a few seconds Push same button selected on remote again. The led will flash on receiver. Procedure complete.

What is the purpose of a local oscillator in mixer?
A local oscillator is a device that generates a sinusoidal signal with a frequency such that the receiver is able to generate the correct resulting frequency, or intermediate frequency (IF), for further amplification and conversion into audio detection. There is one local oscillator in a single conversion super heterodyne receiver where heterodyning or mixing is used to generate beat frequencies, which may be the sum or the difference of two frequencies. The local oscillator is usually adjustable and in step with the increment or decrement in the receiver frequency. For instance, if the receiver is tuned to 1,455 kilohertz (kHz) as radio frequency input (RF-in), the local oscillator frequency (LOF) may be set to 1,910 kHz for a so-called high side injection. The two signals are fed to an electronic device known as the mixer, which derives LOF - RF-in = IF or 455 kHz, which suggests why amplitude modulation (AM) broadcast receivers have about four stages of low-power amplifiers tuneable to 455 kHz.

Draw and explain the super heterodyne receiver?
A superheterodyne receiver is a type of radio receiver that converts a high-frequency signal to a lower intermediate frequency (IF) for easier processing. It employs a mixer to combine the incoming radio frequency (RF) signal with a locally generated oscillator signal, producing the IF. This allows for improved selectivity and sensitivity through the use of filters and amplifiers. The basic components include an antenna, RF amplifier, mixer, local oscillator, IF amplifier, detector, and audio amplifier.

What GMRT do after receiving signal?
I persume you mean the Giant Meterwave Radio Telescope (GMRT) in India. The way a received signal is processed is equivalent to the working principle of a double-super-heterodyne-receiver. That means that a received signal is filtered, mixed with another frequency and filtered again to downscale it for transport from telescope antenna to the observation room...here it is mixed and filtered again so that the signal is be downconverted for recording and data analisys.
