2968

The uBITX v6 kit is an excellent choice for those who are looking for a general coverage transceiver with minimal controls. This compact, single-board design covers the entire HF range and offers a transmit power of up to 10 watts PEP on lower HF bands, dipping to 5 watts on 28 MHz. It supports both SSB and CW modes, making it versatile for a variety of radio needs.

One of the standout features of the uBITX v6 kit is its simplicity. The kit is designed to be simple to build and align, even for those who have never built a radio before. It is based on an Arduino Nano controller and a Si5351 for all local oscillators, which provides excellent performance and simplifies the oscillator system.

uBITX Kit

The uBITX v6 kit features a double conversion, superhet architecture and can be scratch-built for less than $50 or bought as a kit. Its minimal controls simplify the front panel, while retaining all the necessary functionality in a simple menu system that works with the tuning knob and a single function button.
It supports two VFOs, RIT, calibration, CW semi break-in, meter indicator, and more.

This kit has been in regular use on forty and twenty meters for testing purposes and has proven to be a reliable and versatile transceiver. While achieving competition-grade performance from a multiband homebrew transceiver is a complex task, the uBITX v6 kit achieves a more modest design goal with far lesser complexity.
Its customizability allows users to modify and accessorize the radio to suit their needs, making it an ideal choice for anyone looking to build a unique and personalized radio.

uBITX is produced and sold by HFSignals, and price is around 200 USD.
