Penntek Manuals & User Guides

Penntek is a specialized electronics brand founded by John Dillon (WA3RNC), catering to the amateur radio community. The brand is best known for its high-quality QRP (Quarter Power) CW transceiver kits, including the popular TR-25 and TR-35 models. These transceivers are designed with the portable operator in mind, offering lightweight, durable, and energy-efficient solutions perfect for SOTA (Summits on the Air) and POTA (Parks on the Air) activations.

Penntek kits are distinguished by their builder-friendly design; complicated surface-mount components are often pre-installed, leaving the user to assemble through-hole components. Features typically include crisp OLED displays, wide tuning ranges, and robust receiver performance on bands such as 40, 30, 20, and 17 meters. Penntek provides comprehensive documentation and support, making their radios accessible to both experienced builders and those new to kit assembly.
