The Quansheng QPT (V1.1) project introduces a significant modification for the Quansheng UV-K5 (K6) handheld radio. This system enables full-featured CW (Continuous Wave) and DSB (Double Sideband) operation on the 2-meter and 70-centimeter amateur radio bands.
Developed by enthusiasts of CW operation and participants of the annual RAH (Radio Amateurs Hiking) event, the QPT system enhances radio communication efficiency and reduces power consumption compared to traditional FM modes. It is particularly beneficial for maintaining clear communication in amateur radio services where CW remains highly valued for its effectiveness.
The system integrates its electronics into a standard Baofeng handheld microphone, powered by a CR2032 battery offering extended operational life of 200 to 400 hours. It supports features like automatic transmission of call signs, emergency signals, and Q codes, as well as Morse code keying via a built-in paddle. The system also includes temperature sensing capabilities using both internal and external DS18B20 sensors, useful for monitoring environmental conditions or personal body temperature during outdoor activities.
The QPT system offers various operational modes accessible through a menu system, allowing users to configure settings such as Morse code speed, emergency message transmission, and temperature reporting. This makes it a versatile tool for radio amateurs engaged in hiking, emergency communications, and general radio experimentation.
