TO ORDER MAKE OFFERS AND TO SEE OTHER ITEMS OFFERED GO TO: https://www.ebay.com/str/sparko6079?_trksid=p2047675.l2563 NOTE: I can custom make almost any extender board. With basic information about the extender you need I can program the automated CNC machine I have to produce what you need. I do not charge extra for customizing a board or set of boards needed to service most radios and test equipment. With basic information from EBay buyers I produce a set to sell to them through EBay and then offer the same extenders to other buyers on EBay. If you have an idea for an extender board or extender board set you or others need please contact me so I can make up a design and offer it on EBay. Thanks and best regards John WA1ESO
