hello and thanks for looking, the switch went bad on my ranger sdm 1000 and i can't find one.if you have a sdm 1000 microphone you would sell let me know,mine was my favorite mic. and i used it every day,so if you can help me out i would pay a fair price. i also would like a ranger ac 7000 microphone, i had to sell it a few years ago when my family fell on hard times. thanks again and happy DXing.
