To install the IFace card inside the ICOM IC-735 follow the steps below.
The IC-735, like other radios, has a fairly complex configuration and uses different intermediate frequencies. We are interested in having a “wide band” signal, so it will have to be picked up before the main band pass filter. The sequence of operations to be performed to obtain a bandwidth sufficient to realize a panoramic receiver around the chosen IF frequency (70.451 MHz) is shown below. The path of the TX and RX signals is partly separate, so the PTT command to disable the IFace during transmission may not be necessary. The following images show the point where the IF signal will be taken and the power supply.
Now we need to locate the points where to connect the electric cables to the IFace. The following images illustrate where to get the various signals on the MAIN UNIT.
If you like the idea and the goodness of the proposal buy an IFace using the button 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.
