These rigs can be connected to a computer using a USB cable for CAT control and firmware updates, or the use of an optional SCU-17 Interface Unit to support USB Audio In/Out, TX Control (PTT, Key, and Shift). In a superheterodyne receiver, AGC is usually applied to the IF amplifier, and there may be a second AGC loop to control the gain of the RF amplifier to prevent it from overloading, too. Amateur stations must record the call sign of the primary service station before operating on a frequency assigned to that station B.

The IC-7700 employs mechanical relay BPF switching, a digitally tuned pre-selector, and three Hi-spec 1st IF filters (roofing filter) in a Dynamic range characteristics (in 14MHz band) clean and simple double-conversion superheterodyne design. In addition, the general coverage receiver covers 135KHz to 30MHz in all modes. A superheterodyne receiver, often shortened to superhet, is a type of radio receiver that uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original carrier frequency.It was long believed to have been invented by US engineer Edwin Armstrong, but after some controversy the earliest patent for … Automatic Gain Control, AGC: An automatic gain control is incorporated into most superhet radio block diagrams.
