    Excellent simple Tap and well demonstrated.👍

    Great video but what kind of toroid and winding wire did you use. Thanks a lot.

      The wire is nothing special , and you don’t really need the toroid , you could just loosely wrap around the center core , the toroids are just standard ones , nothing special.

    Hi what are u using for a two tone gen? Did u build it?

      I built one a while ago , it’s on my videos a good few months ago

    Very nice video,
    How come you don't sell those 2 Tone SSB boards in kit form if you don't mind me asking?

      I didnt think there would be any request for them.

    Would have liked to have see the SII and S2I the insertion loss and the dB isolaton of the tap

      I don't think Peter at TRX bench even did that .

    51 ohm resistor in series?

      Yeh , a slight error only spotted way after making the video .

    Hi there
    Nice video
    Want to make one of these myself
    What size metal box did you use ?????
    Keep up the good work

    Can share the diagram

    • @MicroChipz

      Look for trxbench on TH-cam , that’s the diagram I used .

    I used this design and it worked to a certain extent but my frequency meter was 24Hz out, so instead of using the torroid, I used a stiff piece of insulated wire and ran it just off the bottom of the box and now the frequency meter reads correctly. I suppose the answer is, whatever works.....

      I dont know it made your reading off , as its just a rf pickup, thats not directly connected to the load, maybe too much signal , maybe not enough , but if your way works then its a win. My design was taken from TRX bench

    Have you got a link where I could buy these parts from as I have already blown up one cheap Chinese signal generator or would this not work for that? And a goldstar frequency counter

    • @MicroChipz
      @MicroChipz  ปีที่แล้ว +1

      All parts came from eBay , trxbench did a video on this

    Excellent tip, but my frequency counter uses a 1Mohm impedance on the input for frequencies below 30Mhz, so I came up with a version using a double throw switch, to switch between 50ohm and 1Mohm resistors feeding the output. Works a treat.😊

    • @MicroChipz

      Yeh my counter has the same , never had any issues using a 50 ohm terminator, maybe for small signals it would matter .
