   Why don’t you show how to set it up and what you use?

     Hi Charles,

     This is a forwarded post so I have no other information other than what’s in the post.

     73,

   Nice work Theo. I had issues with mine on Windows 7 64bit. I will probably not go through USB and just make up something with a direct serial interface.

   No I believe you need a sound interface also.

   Can confirm you need a soundcard interface too. Something like a Singalink USB would be ideal.

   I built my own interface with a 8ohm-1kohm transformer and a 600:600ohm transformer, a few caps and 2 x 1k resistors and a 1k pot. Works a treat, now I just hacked a USB 7.1 sound card $2 from ebay and fitted it all in a box with a opto-isolator on the PTT lines with a max232 and its better than a signalink because it costs me $5

   Hi Edwin. I’m not quite sure what you mean. I am very happy to try and help you if I can, but I’m just not sure what you need help with. 73 from Theo – VK5MTM.

   Ok. All I am using is a USB CAT cable. I bought it from eBay. Youtube won’t allow me to paste the link here, so if you go to eBay and search for “FT-840 USB CAT” you will see the cables for sale. I bought mine from the seller named “phutping”. Hope this helps. Please feel free to ask for more assistance and I will do my best to help you.

    I have a FT-840 also…what kind of CAT control do you have? What do you use for PSK? I bought a CAT cable and use Ham Radio Deluxe, but computer crashes after 5 mins or so…I’m thinking it’s the cable.

    I don’t use any other CAT control besides the cable and HRD. I’m not setup for digital modes (I have no sound interface) so I don’t do PSK. I too get random intermittent crashes when using HRD & CAT. It gives me the shits. Using CAT control with another app (VK Contest Logger) I don’t have any issues.
