There are other very compact options that can work very well. At the Milwaukee hamfest about seven years ago, I bought what was probably a salesman's demo package of five different Plantronics miniature headsets. I think I paid about $15 for all five. All had both earphone and electret mic, and came with connectors that did not fit a ham rig, but they were very different from each other in terms of their physical design. I cut off the connectors and made adapters to use them with my ham rigs (at that time, a K2, TS850, Omni V, and 746). All of the mics worked fine with all of the rigs. Headsets like this can be found at consumer electronics stores like Fry's for under $30. You'll have to figure out the wiring. The shield is always common, use an ohmeter to find the earphone wire (listen for the click), and the other wire is the mic. See my Ham Interfacing pdf for wiring info. 73, Jim Brown K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
