• Ribbit digital text messaging mode for HF/VHF/UHF - Ribbit is a novel digital text messaging mode for VHF/UHF communications for recreational and emergency use which radically increases the density of information transmitted by spectrum used. It leverages the computing power of the modern smartphone to increase the capabilities of any Handy Talkie without requiring any additional hardware or cable. A Ribbit message is fixed in duration at 1250 milliseconds. It is sent over audio modulation with a 2kHz bandwidth centered on 1.5kHz. It is preceded by 400ms of white noise to open analog squelch circuits.

• Yaesu FT-891 Go-Box for POTA - This article documents the author's latest go-box build for outdoor ham radio operations using a Yaesu FT-891 transceiver. The go-box is constructed from a plastic "50-cal ammo case" and contains various components, including the transceiver, LDG Z11 Pro autotuner, DIY Yaesu FH-2 remote control keypad, and an external battery. The author details the design considerations, the mounting of components inside the box, and addresses issues related to ventilation and cable management. The go-box is geared for CW operations and POTA activations, with further modifications planned for a microphone and DATA jack. This project allows for rugged, environmentally protected outdoor radio operations while maintaining portability.

• miniVNA PRO Modifications - The mini Radio Solutions miniVNA PRO is the only affordable vector network analyser (VNA) I know of that offers remote wireless operation. This is very interesting because it allows to measure the input impedance of HF antennas installed at height without having to deal with coax cable lengths, baluns nor common mode suppression chokes. However, to render the miniVNA PRO truly field proof, it requires a number of significant modifications.
