Really good, and I like your screen layout and features. Are you
going to open source your sketch so that others can make use of

The project is on the right track.
Everything is already in a metal box (cookie), it is already
possible to transmit, getting about 12W in 40m. and
approximately 7 in 20m. For the other bands I do not have
QSO's in 40m are relatively easy to do, depending on the
propagation, but even with my precarious antenna I have been
able to perform QSO's with EA8 and HB9, in addition to
practically all EA. Keep in mind that I use a mic preamp that
has some compression.
The front-end has changed, being governed by an arduino mega2560
pro and a 2.4 "touch screen.
It is possible to adjust the frequencies of BFO, IF, CW Tone and
an offset if necessary for the VFO. For the Si5351 the
calibration factor and the outputs can be adjusted.
As a disadvantage, this Arduino works at 16MHz and it seems
that, together with the screen, it introduces some noise.
Working now to eliminate it.
I just uploaded a small video showing all that: https://www.youtube.com/watch?v=18RdGJ-0sto
or search for "ubitx EB7ME" on YouTube
Thank you very much Farhan for your great idea.
