Hello everyone. I'm new to the Arduino platform, but I want to know if it's possible to build a ham radio based on Arduino with both receive and transmit capability. It'd need tuning, coax input, USB and audio outputs, and a 10-digit display. Tuning would be either internal or handled by the computer the USB output would plug into. Any assistance would be appreciated. Thank you.
You need only one Arduino but a bunch of specialized modules. You may be better off with a RasPi which only deserves a RF module.
Sure. But you need to provide a lot of information about the RF side of the radio.
Beyond that, you’ll need to consider the shielding, grounds and power supplies to keep the digital noise out of the RF channels, and vice-versa.
The control and monitoring is an interesting project once you get ‘the radio’ built.
Do you have google on your internets over there?
ham radio based on aduino
and spend an afternoon looking at what ppl get up to with ham and Arduino.

By itself, no.
You could generate CW signals in the HF bands, but you would need external filtering to be legal.
Receiving? analogRead() takes about 100us to obtain a value, so you can sample at approximately 10kHz. Meaning VLF. Again, without external components
He is looking for Ham Radio on Arduino.
Indeed. I was thinking the OP would come across lotsa projects that involve ham and Arduino, whether on, with or just nearby each other.
And get an idea of what ppl are doing, what is easy, what is hard, what is possible and so forth…

Look up SDR (software defined radio) you can get these as modules with all the RF stuff on it.
If it is a trancever you then have to use probably a PLL to generate the carrier.
What frequencies do you want to operate in?

Have you ever used a computer controlled antenna tuner? I recently repaired an old one. It has perhaps 24 relays to switch inductance and capacitor values. It also measures the SWR, standing wave ratio on the output and used the relays to minimize the SWR.
Some of the things to get started with.
I'm new to ham radio, so I'd be starting out aiming for a Technician license, therefore 30 MHz and above.
Hmmm. Seriously, do you have a 5 year plan to develop this device?
Look into the Ubitx: µBITX – HF SIGNALS with it's Raduino / Arduino Nano. For actual transmitting, you need good filtering to control the harmonics.
Read my post "Rotary Encoder for Ham Radio"
It has most of what you are looking for.
