2023年7月14日 · ADX is a mono band (actually quad band) digital modes optimized HF transceiver that can cover four pre-programmed bands one band at a time by swapping Band LPF Modules. It can work on 80m, 40m, 30m,20m, 17m, 15m and 10m bands and can operate on four of the most popular digital modes, FT8, FT4, JS8call and WSPR.

A Self Contained 500 mWatt FT8 HF Transceiver Using SiLabs Si5351 and Si4732 ICs. This project was designed and fabricated by Barb, WB2CBA, and Charley, W5BAA. The project …

2024年4月9日 · ADX-S stands for Arduino Digital Transceiver - Superheterodyn. ADX-S is a QRP transceiver with four modes: WSPR, FT8, FT4 and JS8. There are two versions available; one with 4 bands (40m, 20m, 15m, 10m) and another one with 7 bands (40m, 30m, 20m, 17m, 15m, 12m, 10m). ADX-S is open source.

单根 USB-C 线缆，用于处理音频 + CAT 控制. 在所有 HF 频段上实现真正的 5W 输出。 它甚至能在50 MHz频段上输出 12W ！ （只是需要一个匹配6m波段的接收部分）。 【注：但没有提供谐波/杂散方面的数据，希望大家一起来DIY并测试】 坚如磐石的 PA，可处理开路、短路和恶劣的 SWR 条件 （1：10 SWR） 经过测试）。 我们故意使用未调谐的天线对其进行压力测试，并且仍然可以管理 DX（虽然肯定不是推荐的做法）。 坚如磐石的 VFO，即使在暴露条件下也不会漂移。 …

2024年5月22日 · ADX-S顾名思义，是一个简易的基于 Arduino 模块的纯数字收发信机，而加上 S 表示接收从原来的直接变频 DC 改成了超外差 Superhet，接收效果提升明显，加上一系列体验的完善，已经成为一个非常贴近初学者的数字收发信机套件 。
