Raspberry will be fine.
Hardware:
- Use Raspberry
- Add dd frequency counter interface, along idea here
http://www.swharden.com/wp/2016-10-10-raspberry-pi-rf-frequency-counter/
- Add bad data lines, plus SSB/CW mode line interface
- Add shielding / EMI measures as required
Software:
CAT command implementation can be based based on hamlib or Juma TRX-2
firmware (source code available for the Jumma TRX, see firmware on their
website)
Link from Corsair to PC could be by WLAN
