This device adds the capability to add waterfall to a Ham/CB radio.
The newer (and more expansive) HF transceivers already come with the capability of one's visualization of the spectrum/waterfall through a built in display. Older radios can leverage a SDR receiver and through this device, use the same antenna. This device disconnects the input of the SDR when the transceiver is in TX, protecting the front end of the SDR receiver. (JUMPER CHANGE REQUIRED FOR THIS FUNCTION).
