Kenwood TS-570D Panadapter

A Panadapter is know by many names. The most scientific and correct might be “radio spectrum scope”, but the most common in the ham sphere is “panadapter” or “pan-adaptor” in my short experience. Basically, it’s a wide panoramic view of a radio spectrum.

For a ham, it’s normally used in conjunction with a transceiver or a set of transceivers. It’s also common that the computer doing the spectrum visualization is connected to the transceiver via CAT or similar, so that a click in the spectrum view tunes the transceiver to the desired frequency.

To achieve this you can invest in really expensive SDR hardware, or you can go this route (amongst others), which I did with my Kenwood TS-570D:

  1. Same rig and followed your video but I get no signal in HDSDR. If u plug in a spare antenna like the one that comes with the USB dongle I can hear and see local freqs. I even got omnirig working, but it appears nothing is coming out of those if pins…even made another cable and tested continuity with a multimeter. Is there something obvious I’m missing? Thanks for a great video!!

    • Jay,
      I really have no idea. Are you using the same dongle? n1vca said in a comment on the youtube video that the IF port impedance and the dongle antenna impedance should be as close as possible. Perhaps that is the issue? I don’t know enough about impedance to know what I’m talking about here…

    • I also followed the instructions from the video and received the same outcome as you. According to the TS-570D schematic, the pins used are labled “CN3” and described as “MCF adjustment signal input” and “GND” in the service manual.
      I’m using SDR# software and a RTL-SDR V3. Any additional information would be helpful.

      • Cheyenne, thanks for commenting!

        I’m currently working on getting back into the hobby after having discovered DMR and from there gone on gotten a couple of “real” QSOs. So now I’m getting the Kenwood out of storage, and thinking about what antenna to build.

        I’ll get back to you if I get the RTL-SDR stuff working again.

  2. Hello dear OM.
    It’s been a while, since the last posting…
    Ist there a conclusion for this “No signal” in the pin You are using?
    I have the same model (TS-570 D) and it happened exactly the same. Tried IT with sevral dongles. No success!

  3. I use a RSP1A SDR connected DIRECTLY, just like this video, to a Kenwood TS-570DG. I just left the lower cover, the top of the filter open, there’s space to introduce the SDR RSP1A to the open carrier of the transceiver. Short cable all. Very good, very good results with SDR-CONSOLE v3.02 software, both at RX and TX! Tnx SA6HAM! 73 de Calin YO2LOG´╗┐

  4. I also followed your instructions from your video and received the same outcome as Jay. Are there any radio adjustments as to IF filter, or receive frequency restrictions?
