In a previous article we presented how to install the IFace card inside the Kenwood TS-2000 to obtain the IF signal of the HF and 50 MHz bands in order to send it to an external SDR. Now let’s see how to get the IF signal for the VHF and UHF bands. 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. In any case, the one described here is the sequence of operations to be performed to obtain a bandwidth sufficient to provide a panoramic receiver around the IF frequency relative to the VHF and UHF bands.

The point where the IF signal is taken can be identified more precisely using the electrical scheme as shown in the following images. The electronic card of interest is the one named TX-RX2 and the signal can be taken R167 or C233.

Now we need to find out where to get the power supply: energy can be taken from the CN 12 connector or from the CN 17, 14S signal.

• PTT: for the TS-2000 it is not required because the reception circuit is automatically muted during transmission.

In the images that follow you can see the points where to take the IF signal: therefore the installation is really simple. Pay attention, for this RTX the IF sampling point is on the bottom layer of the TX-RX 2 UNIT.

You can by IFace 2 simply making click on 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.
