    PTT on yoke

    Minnie just has a 2 place portable intercom with a PTT velcroed to the
    yoke.

    I'm thinking about having a 4 place panel mounted intercom installed.

    I asked my avionics guy about also having PTT switches installed on (in)
    the yoke. I've seen that before.

    He said he didn't think it could be done with my yoke.

    He said he thought someone made replacement yokes for Beechcraft that
    would accommodate a PTT but that he didn't know the name of the company
    and thought they were expensive.

    Anyone have any info on installing a PTT on the standard Beech yoke or in
    the alternative where to get a yoke that will accommodate a PTT?

    PTT on yoke

    Check on the before and after pics on Myplaneonline.com of my plane.

    My avionics guy did it. Do you have the aluminum plugs at the top of the
    yoke ? He ended up running the wire along the shaft but is come out of the
    yoke right near the shaft.

    Look close and you can see the coiled cable from the bottom of the yoke to
    the panel just under the shaft.

    Had a PTT on the standard yoke on my 63. Dunno the details, just that it was
    there.

    AM














    Cloyd, I also installed a panel mount intercom last year. When I bought
    the plane, the pilot's yoke had a custom leather cover with build in PTT
    plugged into the portable intercom screwed into the center console. Before
    I had the avionics guy do the install, I bought another leather yoke cover
    for the copilot side (PTT on right side) and he wired them direct. The
    coiled wire exits the leather cover at the bottom by the shaft so the end
    result looks great.

    These leather yoke covers are expensive ($150?) but are custom made for a
    Beech yoke and extremely tight fitting. Solves a couple of issues - the
    tan leather cover really adds a nice touch to the interior, covers up the
    old, cracked yoke, and adds a PTT. I can't remember the vendor, but if
    you google "leather yoke cover" you should find it. They make custom
    covers for all popular yokes.

    PTT on yoke

    My SuperMouse had a pilot's PTT when I got it. But when I upgraded to a
    GMA340 and added "real" 4-place intercom jacks my avionics guy said he
    couldn't legally drill the existing yoke plus even if he did with 40
    year old PVC the outcome was risky at best. He ended up wiring in a
    portable PTT sitch that fit fairly well with a velcro strap on the
    inside side of the yoke. It's not perfect but it works - one minor
    advantage is I can easily move the PTT to the left side of the yoke if
    preferred.

    The leather cover idea is attractive and I might follow up on that at
    some point.

    PTT on yoke

    My yokes have the PTT mounted inside the yoke and they are original Beech.
    The wires run on the outside of the shaft and where the yoke expands out the
    wire goes into a drilled hole and to the PTT switch, it looks good and they
    work great, if I remember, next time I am at the airport I will take a
    couple of pictures.

    PTT on yoke

    "Dunno the details"-- What I meant by that was don't know if mine was
    factory original (but doubt it) or added on at some point. Never saw anything in
    the logs showing this addition, then again the original logs up to ~ 1,000 hrs
    were lost. I also had the wires (coiled telephone type) running down the
    outside of the shaft.

    PTT on yoke

    Seems like the older I get, the more I have to write. And as odd as it may sound, I don't have time to write less.

    Summary: The Beech yokes used on our planes consist of a welded-up aluminum tube core structure. This weldment is placed in a mold, and the ergonomic plastic is cast around the weldment, to provide the ideal shape. This is fact; I have much of the drawing data, and the part numbers assigned to each stage of the process. This is also why cracks in the plastic do not render our yokes unairworthy; the plastic is simply cosmetic.

    The yokes come with translucent plastic plugs that cap the top holes. These have usually been painted over the years, and have often been crystallized by sunlight. I have seen metal hole snap-in plugs used, but I don't think Beech ever used them. Having said that, I have found a lot of other anomalies apparently original from the factory; so who knows. At Sun-N-Fun I found what appeared to be a solid cast aluminum yoke that was shaped like ours (but with a different shaft attachment). It carried a PN for one of the old Beech Twin Bonanzas (50-series).

    The Beech factory method for installing PTT switches was to pop off the top cap. The plastic or aluminum plug that caps the aluminum center tube, inside the upper cavity, got a small hole drilled in it. Another small hole was drilled vertically into the bottom of the yoke hub, aligned with the tubing. A small pair of wires was fished through for the PTT. The PTT itself was mounted in the left hand-grip, in a small hole, aligned with the trigger finger. In most cases, the PTT hole was drilled deeply enough to seat the switch, but with a shoulder to stop it from falling into the yoke cavity. The switch is usually just a friction fit in the hole. A smaller hole goes through into the cavity, to connect the wires. At the bottom of the yoke, a connection is made to a spiral cable, which is usually clamped to the bottom hub of the yoke (and under the instrument panel at the other end).

    This was the standard method used by the factory, and should be accepted in the field. In many cases involving autopilot disconnect and electric trim switches, a significantly larger hole was drilled in the pilot's yoke (top and bottom), for the much larger wire bundle needed for the added controls.

    I have seen some Skipper yokes that have a different configuration, with an exit hole drilled fore-and-aft next to the hub. I have also run across some yokes that apparently became blocked in the inner tubes, most likely during the molding process, and proved impossible to get wires to pass completely through; even though their structure was clearly the same.

    PTT On Yoke

    My Sierra had a PTT on the Pilots yoke when I bought the plane. During my panel makeover 3 years ago they not only replaced the ptt switch but also added three additional swithches. One for my autopilot mode, autopilot disconnect and altitude hold. They also added a PTT to the co-pilot yoke.
