Our buffer interface named IFace can be used to add an SDR panadapter to the glorious Icom IC-R9000.
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 uses different mixers. In particular, we will have to use the second one of the RX chain because the IF frequency will be the same for all the bands, 10.7 MHz. The following images show the block diagram of the radio.
The following two images show 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.
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 images show the sampling point for the IF signal and for the power supply for the buffer interface.
The use of PTT signal is not required, it’s a receiver!
