Our buffer interface named IFace can be used to add an SDR panadapter to the Icom IC-775 and IC-775DSP.
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 imagea show the block diagram of the radio. For the IC-775 and IC-775DSP the first IF is shown in the table in the following image.
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.
In order to purchase an IFace use one of the buttons below.
ATTENTION: Though installing the IFace is not difficult, you do this at your own risk. TSP S.r.l. is not responsible for any damage, unwanted side-effects or whatever.
