    Almost every week, a New Radio Amateur is seeking to wire
    Current Asian or Surplus LMR Microphones using Modular Plugs (RJ-45)
    to older, legacy radios that accept Circular Foster (CBC) connectors with 4, 6, or 8 pins.
    Here is a workbench “widget” to help and speed up that process.

    I especially like that: 1. The 'widget' clearly identifies pins 1-8 by numbers that are easy to read, as many jacks do not. 2. Screw terminals are used for multiple tests and re-arrangement of wiring. Type 110 and other insulation displacement methods can result in frustration if the length of spare solid conductor wire becomes short. Screw terminal type includes nearly 'short-proof' barrier between terminals- where 'bisquit block' screws do not. 3. Provision is made for mounting beyond double-sided tape or shaped plastic faceplate sold separately. 4. Shield connection may be used, if desired. 5. Price is reasonable considering that terminal strips are included for convenience of rapid connections. Thanks!
