SDR interface for the TS-570D and the TS-570DG

These are the instructions to install the IFace interface inside of the Kenwood TS-570D/G. The installation is very easy.

The TS-570D / G, like other radios, has a complex configuration and uses several intermediate frequencies. We are interested in having a “broadband” signal, so it will be picked up before the main band pass filter. The sequence of operations to be performed to obtain a sufficient bandwidth to create a panoramic receiver around the chosen IF frequency (73.05 MHz) is shown below. The path of the TX and RX signals is partly separate, so the PTT + signal to disable IFace during transmission is not strictly necessary but can help isolate the receiver during transmission. The following images show the point where to take the signals 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 TX-RX UNIT.

If you like the idea and the goodness of the proposal buy an IFace using 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.
