Irwell HF Transceiver Digital Modes Interface

 Time to catch up banner


My last blog post was made on the 10th July 2022 which is just a tad over four and a half months ago,  traditionaly I do not spend a lot of time during the summer months working on homebrew projects but now that autumn & winter are here it is time to melt solder again and play catch up!

Irwell HF Transceiver VFO Oscillator Module Re-Visited Pt2

For part 1 of revisiting the Digital VFO Oscillator  module click here.

 Si5351 TCXO xtal replacement


In the last blog post I looked at replacing the three 25MHz xtals that are used for  reference clocks on the Si5351 IC's located on the the oscillator module of my digital VFO. 

The mod/upgrade to a single TCXO (temperature controlled xtal oscillator) module was carried out and tested in a lashup fashion with great success. In this blog post I report on the fabrication of a new PCB that is TCXO ready!

My last blog post was in February of this year (2022) and it is hard to believe we are now at the end of the month of May and close to the half way point of 2022!

I expect followers of the blog may have been left wondering if my Irwell HF Transceiver project has been abandoned but alas that is definitely not the case!
