Introduction I have been working on the hardware frontend for LICO recently. After much reflection, I decided to design my own pure hardware frontend. Compared to mobile apps, a pure hardware frontend is not affected by the strict background scheduling policies of the Android system and can directly control various hardware components, simplifying the control process. Standalone hardware is not without drawbacks—its power management is far inferior to modern smartphones—but my requirement is for always-online operation....

Here I share my process of DIY Inverted V antenna and some insights. Note, the following generally refers to the shortwave bands, namely radio waves with wavelengths from 80m to 6m. (For the 160m band, honestly use an inverted L or GP… or add inductance if necessary) Introduction to the Inverted V Antenna An Inverted V Antenna is a type of antenna similar to a horizontal dipole antenna, but its sides are bent downward, typically forming an angle of 120 degrees or 90 degrees between the dipole legs....
