RTX is satellite based unless you are in the Fast area which uses CORS networks for fast correction acquisition. To use the RTX Fast you do need the RTK unlock, but no radio or modem.
To go with Digifarm or a state CORS network, you would need a modem like the ones you referenced or a phone/tablet with cell plan and bluetooth adapter. make sure those modems are not the 3G only modems as they are going to quit working in the near future in most areas.
You would need a base station if you go with CORS or Digifarm.
