For a long time, members of the HamCQ community have actively shared excellent logging software. The community also planned to implement the Unified Logging Platform several years ago, but due to various obstacles, it was unable to be implemented.
With the help of AI, we leverage the open-source Wavelog project (under MIT license) and package it as a Software as a Service (SaaS) solution. This allows each user to have a fully independent and complete Wavelog tenant environment immediately upon registration.
Wavelog is a modern web-based amateur radio logging application, specifically designed for managing communications records.(QSO)Designed in conjunction with various award milestones.
The following provides a brief overview of the architecture of the HamCQ Echo platform:

With HamCQ Echo, you get the following benefits:
