Lu -- thanks for the detailed rundown on the Koss unit. I don't know what radios are at NQ4I, but I'm headed to PJ4 for CQWWCW, where FT1000MPs are used. Before and after the contest, I may want to work SSB, so I made a simple connector adapter for my CM500 mic (8-pin mic plug, one resistor, short length of coax, to female TRS 1/8-in jack). Last night, I checked it out with the MP that's still in my closet as a backup rig. I had to turn down the mic gain a LOT, but K6XX tells me that it sounds fine. The resistor goes from the 8VDC pin on the mic connector to the MIC hot pin on the connector. I think I used 4.7K or 6.8K. Any value in that range is fine. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
