It's not the ?BITX that has the clone, it's the Nano that's inside it that can be cloned. Chinese copies often have the older bootloader embedded in them and require the CH340/CH341 driver to be able to download the compiled code from the PC to the ?BITX's Nano. Since I'm a fixed-income, retired teacher, I buy cheap Nano clones rather than the "real thing" from Arduino. (I've tried poor...wouldn't mind trying rich.) Also, a lot of clones seem to have the Blink sketch installed when you first power them up. (I think they use Blink to test them??)

Just pre-form the wire leads so that they match the SMD solder pads. Then tin them. That way you'll only need minimal heat to tack the resistor to the pads.
The SMD pads and traces won't take a lot of heat before lifting from the board. I use a 20-watt iron with a pointed tip for SMD. Solder time should be 1-2 seconds per pad.

Re: Adding a SI5351 on uBITX for 116MHZ
Michael,
I will assume that what John has stated is true.? Then on way to do the control might be through a second Nano as Dr Lee did with the stand-alone signal analizer:
You would need to hack into the code to add the I2C command pass through to the second Nano.? In essence, it would be two Raduino boards connected via the I2C that is used for the display.? That would get around the fixed I2C address of the si5351.
It might be less expensive to go the alternate QFN' A chip and a custom board.
FWIW

Re: Adding a SI5351 on uBITX for 116MHZ
In addition to the FW issue, you have an I2C addressing problem.
The 10-pin Si5351 has a fixed I2C address (0x60).
You'll need a second Si5351 to have a different I2C address.
Only the 20-pin QFN 'A chip has a way to change the I2C address
(pull-up/down on A0),
but I don't see any cheap modules with this part.
SiLabs does offer custom configurations that includes a different
I2C
address.? You can usually sample parts like this.? Check out their
FAQ at:

I have already tested with a separate arduino and a SI5351, it
works and I get 116MHz (I found the file on the net). The only
problem is that I don't know how to add it in the KD8CEC software
to order the 2nd SI5351 with the same arduino that I want to add.
I know I'm complicated. Thank you Keven

Howbout just specifying it to generate at half that, or 58 MHz and run it through a doubler?

Re: ubitx 6.2 bench calibration frequencies?
Hi John,
That sounds like a reasonable procedure. Only missing detail is that in BFO cal step 3, you'll want to set the mode to USB, but that's the standard for 20m, so perhaps that was a given.
While calibrating the oscillator is a science, the calibrating the BFO is a bit more of an art. You may find that you don't actually want the strongest signal at 1.5kHz, but rather that you want to suppress the opposite side band better, or perhaps you want to get a more natural sound, etc. For your reference, on my v6 I have the BFO at 11.055.300, so I'd expect you to find a suitable value for your preferences somewhere in that neighborhood.
