    I recently purchased a the above radio used and in apparently GREAT condition.

    I'm also a new HAM.

    I found the User's Manual online.

    Q: Can somebody PLEASE help me better understand how the needle gauge works-what it represents?

    Any input is welcome and I THANK YOU in advance.

    What's a needle gauge? Do you mean the panel meter, which shows received signal strength on receive, and things like ALC, power amplifier collector current, etc on transmit?

    The IC-761 is a great rig, although now it's quite old and they're prone to various interesting failures with age. Are you having a specific problem with it?

    Yes. The needle gauge is the is the s-meter.

    Also, can you tell me about the internal antenna tuner, please?

    Q: If I make a dipole antenna for 160 meters, does that mean that due to the rig having an internal antenna tuner, that I can operate (rx/tx) on 160 meters thru 10 meters?

    Q: What is the "speech" button used for?

    Please and Thank You in advance for any input you can provide.

    That's called a "meter."

    No. Of course I guess you realize a 160m dipole is 262 feet long? Do you have the space for that? But in any case, no, that won't work unless you feed the dipole with open wire line and use an external balanced line tuner. The internal tuner is to "touch up" antennas that are nearly matched to begin with and in no way can make a 160m dipole work on all bands.

    Right now, I'd ignore that. You need some local, hands-on help. Are you a member of a local radio club, like the Pasadena Radio Club, which is pretty close to you? If not, go to a meeting, join the club, get a local to stop over and help you. That's the way we all learn. The internet is no substitute for a local "Elmer."

    Glad you're getting set straight, and the 761 is an outstanding hf rig.

    Another IC-761 Question

    Hello All,

    What is are the adjustments under the panel on the top of the rig near the audio speaker? They are not mentioned in the user's manual as far as I can see or have read....

    Please and THANK YOU in advance for any and all advise/wisdom.

    FYI: Since my last post I have built a 40 meter dipole and have made more than a few contacts =)

    Sure they are, on page 37: The auto tuner presets.

    If the auto tuner is working it would be very wise to not touch these at all.

    The "speech" button enables an added on optional feature called a voice synthesizer unit. If installed, when the button is pushed, it will report to you the frequency the rig is on in a synthesized voice in English. It is primarily for those with disabilities that may need it, bad eyesight etc.
    The 761 is a handful of radio to be sure. Everything it does is covered in the owners manual.
