Thread: Ts-450 Acc2

    Default Ts-450 Acc2

    I'm new into HAM radio and have a Kenwood TS-450S/AT. I wanted to start working Digital HF problem is I have no idea how to connect the radio to the PC. I looked a t the manual but it explains how to connect the ACC2 to a TNC or a RTTY keyboard, now how do I make it work directly to the PC, so here is what i think is the way but wanted you to tell me if I'm right. So I connect the headphones output to the mic on the pc, then at the ACC2 on the radio I send the pin 3 (Left channel I suppose) and 4(R-Channel I suppose) (AF Input) to the sound output of the PC. Don;t know where to send the other pins

    The other way I can think of, is that instead of connecting the ACC2 I should do with the MIC on the radio. but the only PIN I understood was the MIC PIN 1 which I suppose I should send to the Sound output of the pc. I don;t have any idea where to send the GND (STBY), the GND (MIC), the NC, the STBY and the 8V pin.

    So that's it, I'm kind of confused.

    The easiest way for me was to buy a RigBlaster Plus which has a extra cable you can buy already wired to connect to the ACC2 socket on my TS-570.

    I wouldn't connect the headphone jack to the mike input unless you have a way to reduce the level.
    If you have a Line In that is the one you would want to use.

    When I first started out, I just had a lead from Line Out to the mike input, of the rig, (with 1000:1 resistor dropping network)
    I also had a lead from Headphone out to Line In for audio.
    Not the best as you have no isolation, but it worked.
