I've added some pics in the Pictures section of my project in hopes of helping.
1. I used one of the white protoboards and jumpers so I could easily switch from the original display to the nice TFT display
2. To switch I remove the raduino board, add 6 jumpers from the mega 2560 and 3 from the adafruit si5351 board to the proto board.? Note the scotch tape holding the jumpers in position.??
3. A collection of the male-male and male-female jumpers is a must
4. The wires are full length until my plastic cabinet gets here
5. The 3d printed panels found on Amazon are handy for mounting all the external parts.

Finding a few goofs was easy this way!
I failed to sign up for the hints/tips here so I'm behind on the essential mods I need to do.
I have a poppling sound in receive, along with some hum. A new supply and a buck circuit to get the mega2560 voltage down a bit from 13 volts come next.

Hats off to Joe & SP for their efforts and their persona help.

Good to see? progress.?

Don't forget to add some hash filters at the output of your regulators - they make a huge reduction in noise.

I run mine? Atmega around 9v - ...I will take full 13.00v - but i runs very well and much cooler at 9.00v

As for mods, my number one was to eliminate the Pop / crackle on? TX? and also when it changes back to RX.

Nice and quiet with that mod.

Full user manual almost finished?
