Parts and Components

Years ago Oak Hills Reseach supplied parts and components to the QRP building community.  We're reviving the tradition, starting with a few hard-to-find parts that we have access to in quantity.  We can't always give you the lowest price on the market, but the difference will be relatively painless if you include your parts with another order from OHR or Morse Express.

Please note that we do have a minimum $10 order exclusive of shipping, but that minimum can be met with any combination of products from OHR, Milestone Technologies, and Morse Express.  A good starting point would be our Tools Page.

These are all factory fresh parts (we use NO surplus parts in OHR kits, and you shouldn't either!), and some of them are made exclusively for Oak Hills.
