    The Jackson Bros vernier drive was my favorite for homebrew receivers. I am pretty sure I still have one unused one here somewhere. There really was nothing quite like it made here. Thought you might enjoy this history of the company especially how they got the name, lol!


    For US customers, the drives are available at


    In UK at

    Yes I heard about Mainline's rescue of Jackson when I found out they were making the drives for the FT101 several years ago, and gave them a ring.

    Note that if you need one of the Ball drives for an FT101, you will have to get it from the UK company, Mainline . . .

    I see that the US company only have 1/4 inch ones . . . whereas the FT101 uses a metric size (6mm).

    There are a lot of Jackson Bros 6 mm drives on eBay listed under the Jackson Bros name. If you click on delivery, get rates, it leads to a Mainline page. Prices are still very reasonable. Typically less than $20. The OrenElliot price for one piece of the standard 6:1 vernier with 1/4" shaft is still only $15.

    I need to bring up this old thread so that I can offer my thanks to Frank and Roger for the information on how to adjust the VFO on the FT-101 so that it does not drift. I have an E model and also an EX model and I just now finished the EX and it is NAILED DOWN!
    I started yesterday by turning the capacitor clockwise and today I figured out that I needed to go counter clockwise. All it needed was about a 1/8 turn CC.

    Next is my E model.

    Thanks again!
