  1. i have owned one in the 1980’s….it was a great cb radio….i made many long distance calls on it, until on the end it went very wide on its frequenty…….transmitting on 1 channel… but “broadcasting”over more then 5 channels……

    i sold it… but still regretting it…..
    IF i can find one.. i will buy it (again) ….

  2. Had one in the late 80s / early 90s. Loved it. A powerful and simple to use rig, but for whatever reason I sold it. Regret it now, I’ll track one down one day….

  3. Update:
    The 788 is broken. The up/down does’t work anymore. I checked all cables and connections. I guess a diode or transistor is broken. Or a cold solderpoint again. The well known problem, with the 788 🙂

    I will keep you in update

  5. Hi my name is Lasse and have a Summer Camp 780DX
    My question to you is that you can help me get the facts on the 5 pole microphone connector. Want to be able to connect an old microphone named K40 that has a built-in compressor.
    Would be very happy to have it connected to my Summer Camp 780DX
    Is radio amateur with the single SA7ZWX.
    Thanks in advance 73 / Lasse
