Our buffer interface named IFace can be used to add an SDR panadapter to the Kenwood TS-480 transceiver.
The operations to be performed are very simple, it is sufficient to obtain from its wiring diagram the information on the points where to take the IF signals. This radio, in fact, uses different mixers. In particular, we will have to use the first of the RX chain. The following image shows the block diagram of the radio.
Below is a portion of the reception chain and the list of the various IF signals: we are interested in the first one so as to have sufficient bandwidth for the panadapter. We will tune our SDR receiver to 73.095 MHz.
We now proceed to identify the exact points on the circuit diagram where to take the IF signal to be sent to the IFace. The following images show the sampling point for the IF signal and for the power supply for the buffer interface.
The images here below show where the signals are located on the RF Unit PCB. Please take care that the signals are located on the top and on the bottom layer.
