The 32.768khz crystal oscillator, 2x22pf, 2X4.7k and 22nf is assembled bottom side from the 24pin SSOP adaptor. I used SMD Resistors and condensers, metric 0805. I have no so much problem with interefence as with TFT touch display. The touchsreen make intereferences the receiving. The OLED Display works good. I have a XHDATA D808 world receiver with SI4735 DSP chip. The XHDATA receiver have installed a preamplifier. The Signal is 17db bigger, and this receiver have banppass filters inside.
I soldered the Si4735 chip to an SSOP24 adaptor myself. I soldered the most important components like resistors, capacitors and 32,768khz crystal on the underside. They are all SMD components. I've never seen a SI4735break out port myself.
Yes, the SI4735-D60 only have SSB Modulation support with a patch. Pay attention to the exact type, not all SI4735 types support SSB. SI4735-D60 , SSB support: Yes SI4735-B20 , SSB support: NO !!!!!! SI4732-A10 , SSB support: Yes. Not personally tested. You can get to github.com/pu2clr/SI4735 Here you can look all information,

Where did you get the si4735 breakout board? I can only find them as a chip.

Very nice. Can you share the schematic & software details, please?

It looks very very nice. Good job.
With Ricardo Caratti’s library?
Yes with the PU2CLR (Ricardo Lima Caratti) library.
Onde localizo especificamante essa biblioteca la no meio das outras?
The SI4735 have SSB modulation?
Yes, the SI4735-D60 only have SSB Modulation support with a patch.
Pay attention to the exact type, not all SI4735 types support SSB.
SI4735-D60 , SSB support: Yes

@@pg103flo6 thanks
That wire loom, priceless
Nice work.
Thanks!
Look at a Yaesu FRG-7 and then you'll know how much tech has progressed in 40 years.
