KISS (Keep It Simple, Stupid [1]) is a protocol for communicating with a serial terminal node controller (TNC) device used for amateur radio.This allows the TNC to combine more features into a single device and standardizes communications.

A Radio code is any code that is commonly used over a telecommunication system such as Morse code, brevity codes and procedure words. Brevity code
It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators. The protocol was designed, and a program written initially, by Joe Taylor, K1JT. The software code is now open source and is developed by a small team.
Due to the wide bandwidth of the ADC and DAC, the Red Pitaya can be used as a software-defined radio receiver and transmitter and in other radio frequency applications. [3] HAMLAB, a fully featured SDR HF transceiver with an output power of 10 W based on the Red Pitaya board is released in the amateur radio market in October 2016.
The QSA code and QRK code are interrelated and complementary signal reporting codes for use in wireless telegraphy . They replaced the earlier QSJ code. They replaced the earlier QSJ code. Currently, the QSA and QRK codes are officially defined in the ITU Radio Regulations 1990, Appendix 13: Miscellaneous Abbreviations and Signals to Be Used in ...
In lieu of the special minute marker used in the amplitude code, bit 59 is transmitted as an ordinary 0-bit, and the first 10 bits (seconds 0–9) are transmitted as binary 1. When compared to amplitude modulation, phase modulation makes better use of the available frequency spectrum and results in a more precise low frequency time distribution ...
