    I’m not familiar with the PC-1A, but I don’t think that would work very
    well without some modifications. It interfaces the one telephone line
    connection to mic and speaker. You need to interface the two connections
    from the computer to the radio. Randy

    operating systems? such as mac or linux? i have vista but i rarely use it
    as i find linux to me more stable.

    Unplug the MFJ from the computer and check that you can hear the audio from
    the computer. Make sure the radio is set for USB. Double check the jumpers.

    CQ CQ K7AGE DE KC8YTO – Dude, ever since you showed us the “mic on the
    speaker thingy”…I’m hooked! -lol. I went a step further for a first
    contact test and held the radio mic up to the PC speaker…and it friggin’
    worked! Made my first contact with a guy in Texas (from Huntington, WV
    using a badly tuned wet noodle and around 40 watts!) – Now, of course, this
    is a spit-in-the-eye to modern technology and probably spurious as it can
    get, but exciting nonetheless! – THANK YOU!!! ’73

    Excellent tutorial, for what it is worth being a cheapskate I have run some
    of these modes using just the attenuation and cables to the PC, some rigs
    allow you to use VOX even on phone patch inputs or similar. 600ohm line
    transformers can often be rescued from old PMR base stations although a
    variety of stockists here in the UK do sell transformers suitable for
    avoiding ground loops in this application. 73 and thanks for investing the
    time in making the video.

    Correct, sometimes you need a USB to Serial adapter. Or, the newer USB
    interfaces, that also include the sound card are an alternative. On desktop
    computers, I like to install extra RS232 ports. I think I have 4 on my
    computer now, and I bought a couple 4 port modules in case I needed to add
    more ports in the future. Randy

    @3:50 The best way to prevent windows sounds from using the second sound
    card is to set the “default” audio device. Then the only sound on the
    second sound card will be from the programs that you set to use that card.

    If you’ve just got the mic and speaker jacks of the rig and PC connected,
    couldn’t you just use VOX to key the radio?
