I have an Icom HM-157B microphone for sale. Appears to be in very good condition. It came with a used Icom IC-M802 SSB radio that I just received, but it was the wrong microphone for that unit. I've purchased the correct mic, and now have an HM-157B looking for a new home. See this link on the Icom web site for product details.
Amazon sells them for $112, eBay has a couple used right now for $79 (free shipping). I have no use for it, and would rather it find a new home - and would love for a fellow CF member to have it. Anyone interested for $60 (I'll even throw in shipping, US mainland, via UPS w/tracking number)?
