    I've just purchased another ICOM and I want to control it using ham radio deluxe. I normally use the CT-17 level converter which plugs into the computer, all I need them is a 3.5 lead that plugs into the radio. Are these 3.5 leads just standard audio leads?

    Yes, they are the same, but I'd strongly advise using shielded cable as appropriate. There are also metal 3.5" plugs, which may givee a bit more resistance to RFI.
    P.S. Make sure you get what is appropriate; there are two and three conductor 3.5" plugs.

    Something rather strange has happened and I can't work out why. I've found an audio cable last night and plugged it into my CT-17 and then into the ICOM 7400 which is I believe the equivalent to the ICOM 746 pro US version. Anyway, it wasn't until this morning that I put the radio on to set up the audio. I thought I would put my ICOM 7800 so I could monitor the modulation. However, when I tune the radio, let's say the 7400, the frequency also moves on the 7800. If I key the 7400, or vice versa, then it also operates the other radio. This has never happened before, mind you, I've not had to ICOM rigs connected into the CT-17 before, only a Kenwood and an ICOM. Anybody know what's going on?

    EDIT: it seems that now I have switched on HRD and selected the ICOM 7400 I can now have both radios on and they are working independently of each other. Obviously something to do with ICOM radios connected to a CT-17
