Standard use of connectors is a good thing. It saves the various number of different connectors that we must retain for various uses. However, there is no standards in the ham radio community regarding the use and types of connectors. In the military, they use a different connector for every different application and a different connector for each series of equipment. The result is that no two connectors are really alike. However, the advantage is the fact if one didn't have the proper connector and cable for the specific application, then the user could not connect anything. Both methods are correct just as both methods are incorrect, depending on the users point of view. 73 Bob, K4TAX K3S s/n 10,163 On 8/23/2015 10:25 AM, Jerry Moore wrote: I respectfully offer that it's a very good thing Elecraft used a commonly found connector in their radio designs.
