    Hello, I was given a Henry Radio Tempo VHF/One Plus 2 meter rig.  The radio is in working order, but I would like to mod this radio to be able to work with toned repeaters.  Any thoughts?

    Thanks and 73,

    wow, what an antique [​IMG]

    If no one answers, I have found that the guys at CommSpec have details on almost all the older transceivers.

    OK, thanks.  I'll keep that in mind.

    Yep, that is indeed an oldie now. I remember seeing one for the first time at a hamfest in 1980. A synthesised handheld! I was beside myself to imagine such wonderous technology. And in a small package like that too!!! The guy who had it represented either Henry or some more local ham retailer and he had quite the crowd surrounding him. And trust me, he was NOT letting anyone get their hands on it. If anyone was there taking orders, he wheeled a cart load of orders out with him at the end of the day.

    CommSpec was going to be my suggestion also. They have tone encoders that are VERY small and come with easy-to-follow step by step instructions.

    The limitation is you will either have to choose one CTCSS tone before installation and stick with it, or get one of the boards with external dip switches, and keep the chart handy for changing tones.

    I doubt you'll want to mess with a board that decodes as well as encodes. Those get trickier to install. Encode only should be perfectly satisfactory.

    Here's the link to the company: http://www.com-spec.com/index1.htm

    Good luck.

    Thanks for the link. Yup, this is an older unit, but just to clarify, this is a mobile, not hand held. Two meter, 25 watt.

    Thanks again.

    Ahhhh ok . . . I was thinking Tempo S1, and that is the handheld.

    Commspec makes an encoder that has a rotary switch that allows selection of any of the standard CTCSS tones. Hookup is just as easy, easier in fact because there's room to work inside a mobile rig of that era.

    Good luck.

    Thanks again. I think after weighing the options, I'm going to pick up a good used rig (with CTCSS), and leave the Henry in it's original state.
