These are the instructions to install the IFace interface inside of the Kenwood TS-590S. The installation is very easy. For the TS-590SG see the note below.
The TS-590S, like other radios, has a complex configuration and uses different intermediate frequencies also depending on the band used. This radio requires 2 IFace cards because two intermediate frequencies are used, one at 11.374 MHz and another at 73.095 MHz. We are interested in having a “wide band” signal, so it will have to be taken before the main band pass filter.
The sequence of operations to be performed to obtain a sufficient bandwidth to realize a panoramic receiver around the chosen IF frequency is shown below. The path of the TX and RX signals is partly separate, so the PTT command to disable the IFace during transmission will not be necessary. The following images show the point where the IF signal will be taken.
As you can see below, the radio uses two different frequencies depending on the band chosen: it is therefore advisable to use two IFace interfaces and not to insert a mechanical switch.
Let’s start by analyzing the wiring diagram. We have to find the first mixer and where to take the power supply. From the following image everything will appear clear.
At this point we have to locate the points where we connect the electric cables to the IFace. The following images show where to take the various signals.
Last but not least, don’t forget to provide power supply to the IFace: you can easily find a source inside your radio.
NOTE ABOUT THE TS-590SG
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.
