In Episode 98 of WaveTalkers LIVE, the hosts delve into the practical and versatile use of handheld radios for Winlink communication, highlighting their importance in emergency and amateur radio scenarios. The episode provides a thorough guide on connecting various handheld radios to Winlink systems, ensuring reliable digital communication.
The hosts start by demonstrating how to connect popular handheld radios, such as the Baofeng UV-5R and the Kenwood D74, to Winlink. They explain the necessity of terminal node controllers (TNCs) in digital communication, differentiating between external and internal TNCs. While high-end radios like the Kenwood D74 and Icom ID-52 come with built-in TNCs and sound cards for seamless integration, more affordable options like the Baofeng UV-5R require external sound cards like the DigiRig or Signalink.

The hosts walk through the steps to set up Winlink with a Baofeng UV-5R, stressing the importance of adjusting audio levels, disabling automatic gain control (AGC), and ensuring correct settings in both the radio and the software. They also discuss the challenges of using lower-cost radios, such as potential RFI issues, and emphasize the need for regular practice and familiarization to ensure smooth operation in the field.
The episode showcases several demos, including the use of the DigiRig with different handheld radios and employing Bluetooth for wireless connections with models like the Kenwood D74. The DigiRig's versatility, which allows it to connect to multiple radios with specific cables, is highlighted as a practical solution for operators with diverse equipment.
In addition to technical setups, the hosts stress the value of practice and consistent use of the equipment to avoid unexpected issues during actual deployments. They encourage viewers to take detailed notes on settings and configurations to streamline troubleshooting and setup processes in the future.
The episode also features a demonstration of higher-end radios like the Icom 705, illustrating how these models simplify the connection process with advanced features like presets and direct USB connections. The hosts encourage viewers to experiment with their setups, participate in drills, and share their experiences, fostering a collaborative learning environment within the amateur radio community.
Overall, Episode 98 equips viewers with the knowledge and confidence to effectively use handheld radios with Winlink, ensuring reliable digital communication in a variety of scenarios.
