The TenTec RX-320D is an entry-level SDR receiver with relatively simple design. The circuit configuration is based on a three-conversion superheterodyne in which the last one, at a value of 12 KHz, is made available to the audio inputs of a PC in the phase and quadrature components (I/Q) so that it can be processed by the software to implement filters and demodulations. The output is levels compatible with the sound-card that have a line input, the impedance is 600 [ohms] with 2 Vpp of maximum amplitude. Two options for the antenna, you can use the supplied stylus placed on the top panel or an external antenna that automatically, when inserted the connector, disables the first one. The number of memories in which to organize your list of frequencies and stations has no limits using the computer resources.
You can choose the bandwidth of the digital filters between 34 values ranging from a minimum of 300 Hz, typically for CW uses and digital modes at low speed, up to a maximum of 8 KHz for a comfortable listening, in AM mode, of the broadcasting statrions. The following table shows in ascending order all the selectivity values that the user can set:

|---|---|---|---|
| 300 Hz | 1050 Hz | 2400 Hz | 4500 Hz |
