Dear List members Good morning. I need a bit of help in connecting a Baofeng UV-5R with DMK URIx device. I have googled as much as I practically could, but still could not decide/confirm as to what should be the approach. First of all, I came across the pin-out for the baofeng at Miklor site http://www.miklor.com/COM/UV_Technical.php I have also seen how DMK suggests any generic radio should be connected at http://www.dmkeng.com/images/9080-FRS.pdf And finally, I have found the site that shows how to get the COR out of baofeng http://alaskareflector.org/zl1nc/UV-COS.html Now, my expertise in electronics is sub-zero -- I know some very basics about what component does what, and that's all. So, I have several questions, and would appreciate if someone with sufficient relevant experience could please point me to the correct decision. 1. the URI diagram uses several resistors, do I really need them? Or should I just connect things direct? 2. the main URI diagram shows pin 7 as CTCSS_det and pin 8 as COR_det, so should I connect the COR from baofeng to pin 8? 3. based on what I can understand from all the links above, I should connect large stereo body -> D-Sub pin 1 large stereo ring -> D-Sub pin 22 small stereo tip -> D-Sub pin 21 COR (taken from pin 2 of the IC) -> D-Sub pin 8 Is the above correct? Or do you have different experience? Thanks for your response. Regards Shamim
