Yaesu FT-817: Portable QRP Transceiver Resources
Find a curated collection of links for the Yaesu FT-817, including modifications, accessories, reviews, and operational tips for this popular QRP radio.
The Yaesu FT-817 is a popular QRP (low power) portable transceiver, covering HF, VHF, and UHF bands with all modes. Many operators choose the FT-817 for its versatility in field operations, SOTA activations, and even as a compact base station. Its small size and low power consumption make it ideal for battery-powered use, allowing hams to operate from almost anywhere.
This category collects a wide range of resources for FT-817 owners, including reviews and modification guides for enhancements like wideband operation. Operators can find information on power solutions, such as adapting external battery packs, and interfaces for digital modes like PSK31 using devices like the SignaLink. There are also resources for antenna tuners, CAT control software such as FT-817 Commander, and memory cloning utilities to manage frequency settings.

The article explains how to adapt the YAESU FT817 transceiver so that it can be used to control Kuhne electronic transverters by transmitting at +12V via the coaxial wire. Different FT817 versions imply that some of the modification proposals that have been made so far don't apply to everyone. This tutorial provides a workaround that works with all FT817 models. It makes use of the external ACC socket, connecting an interior tiny circuit board to two thin wires. Follow ON7WP's instructions for using the rear antenna socket. -

An FT-817 ceased transmission on the VHF 2m band, despite the other HF, UHF, and 50 MHz bands operating correctly. Suspecting an excess of input signal during FT-8 mode transmission, they conducted measurements with an oscilloscope, revealing a burnt-out PIN diode, identified as D3003, type HSU277, on the PA unit board. Following the replacement of this surface-mounted diode, their FT-817 resumed operation on the 144 MHz band. -

Inspired by Heathkit, author aimed to enhance his Yaesu FT-817 with audio and RF processing. Design goals included a compact enclosure, PCB simplicity, matching jacks, a visual meter, and a built-in signal generator. Despite challenges in finding a suitable compressor IC for a 5V DC mic jack, he chose the Analog Devices SSM2165/2166 series. Prototyping with a solderless breadboard, author planned a PCB layout for its versatile performance in communication use. -
