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 some solder again and play catch up!
In the
last blog post, I looked at replacing the three 25MHz xtals that are used for reference clocks on the Si5351 ICs located in 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 lash-up 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 halfway 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!
Before I get into the first blog post for 2022, I would like to take the opportunity to wish everyone who follows the blog a belated happy new year.
In
this blog post, I cover work on the first of the transmitter modules for my Irwell HF Transceiver, a multi-mode modulator that is capable of SSB, AM and CW modes.
