The PT1 is a portable SDR amateur radio transceiver. The hardware is completely open-source. While the software is proprietary but licensed free of charge to amateur radio enthusiasts; all amateur. Radio enthusiasts can use the open-source materials to build their own transceivers. The PT1 was designed to provide amateur radio enthusiasts with a portable HF SDR transceiver. That offers exceptional value for the price. The PT1 uses the Pico2 as its core processor, featuring a. 24-bit ADC and a quadrature demodulation SDR architecture. Its hardware performance rivals that of. Professional-grade amateur radio transceivers, offering extremely low background noise, extremely. High reception sensitivity, and excellent interference resistance, enabling the demodulation of faint. Its ultra-compact size makes it easy to carry outdoors or while traveling, allowing. Users to listen or make contacts anytime, anywhere. Special Thanks: Some of the PT1’s hardware and software designs draw upon VK7IAN’s. We have obtained formal authorization from VK7IAN to further develop. The MBPTRX architecture and to use portions of the derived software source code for closed-source.
