Digital VFO & RF Oscillator Module

"For The G6LBQ Irwell HF Transceiver"

Welcome to part 4 of my blog post series detailing the Digital VFO and RF oscillator module for my “Irwell HF Transceiver project”.  

The PCB's have arrived from the fabrication plant so it is now time to get busy with the soldering iron and hopefully call time on this part of the project, or at least for now. Providing there are no issues with the PCB's or hardware all that remains to be done is software updates to coincide with the future development of the project.

Welcome to part 3 of my blog post series in which I present details of the hardware for my Digital VFO and RF oscillator module. This is a significant building block for the “Irwell HF Transceiver project” and we finally get down to component level, PCB design and a functioning module.
