First RF signal all the way through the mcHF.
Now it’s time to read through all the mods and have the radio tuned up 🙂

mcHF is a small software defined radio transceiver for shortwaves, designed by Chris M0NKA. It has the form factor of an Elecraft KX3, but it is equipped with a graphical display with spectrum scope and other bells and whistles. Check out my photos taken while building the mcHF.
Few weeks ago I have decided to resume building my mcHF kit. I have made good progress with the RF board and today I have tested the low-pass and band-pass filters.
After completing the UI board I really wanted to see it work and test it one way or other without the RF board.
Last night I mounted the LEDs, the electrolytic capacitors and the LCD panel. I am using the HY28B which is why the display doesn’t align with the push buttons.
I forgot to post this update but I did make some progress since the last report in June. Finished mounting all connectors, buttons and encoders, see photos below.
Last night I finished mounting all the small parts on the UI board and today the board got cleaned of extra flux (there was a lot).
All parts have now arrived and I am soooo ready to build my mcHF
I have been looking into various options for building my own radios again, this time taking advantage of software defined radio technologies. I’m not crazy about using a PC for running the SDR application. While a PC offers great performance and flexibility, it makes a clumsy radio setup not at all suitable for portable and mobile use.
