In two previous articles we have seen how to install the IFace card inside the Kenwood TS-2000 to obtain the IF signal of the HF and 50 MHz bands and of the VHF and UHF bands to be sent to an external SDR. Now let’s see how to get another single IF signal for all bands, including 23cm (1.2 GHz). Installation is very easy.
The result you can obtain is well shown in the following video.
The TS-2000, like other radios, has a fairly complex configuration and uses different intermediate frequencies depending on the band on which you are operating. There is the possibility of taking an IF signal at a single frequency (10,695 MHz) valid for all bands. This involves a reduction in the width of the displayable spectrum as the IF signal will have passed through some IF band filters. In any case, the one described here is the sequence of operations to be performed to obtain a bandwidth sufficient to create a panoramic receiver around the IF frequency relating to all the bands on which the radio can operate.
However, the displayable spectrum depends on the sampling frequency of the SDR receiver, not on IFace.
The point where to take the IF signal can be identified more precisely through the wiring diagram as shown in the following images. The electronic card of interest is the one called TX-RX UNIT and the signal can be taken among R111, C166 and C167.
Now we have to look for where to take the power supply: power can be taken from the CN 29 connector, signal 14S or 8A.
The points on the PCB where to take the signals are shown below.
PTT: for the TS-2000 it is not required because the reception circuit is automatically muted during transmission.

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.
