In order to buy an IFace use the buttons below. The use of PTT signal is not required because this radio is a receiver. The following images show the sampling point for the IF signal and for the power supply for the buffer interface. We now proceed to identify the exact points on the printed circuit board where to take the IF signal to be sent to the IFace. The following image shows the portions of the schematic diagram of the IF UNIT where we can see the exact points where to sample the IF signal and the power supply.

The following image shows the block diagram of the radio and where to get the IF signal. The IF frequency chosen is 10.7 MHz and our SDR panadapter will be tuned to this. We are interested in the second IF frequency (this makes it easier to operate the panadapter). This radio uses several mixers with complex architecture. The operations to be carried out are very simple, it is sufficient to obtain from its wiring diagram the information on the points where the IF signal has to be taken. The crystal is the reference for the PLL and DDS circuits to achieve these specifications. Our buffer interface named IFace can be used to add an SDR panadapter to the Icom IC-R8500. The IC-R8500 has a superb high receive sensitivity over its entire range, and the built-in, high quality crystal (TCXO) provides good frequency stability of less than ☑00 Hz below 30 MHz less than ☓ ppm above 30 MHz.
