I have for sale the CMP460A waterproof mic. I don't know if it works on the VX5, but it works with the VX6/7/177/127 series. Sells new for $70 plus shipping. I am asking $45 shipped I can take paypal, check, mo, or cash. 73s John AA5JG (ex: W5TD, NE0P, N0EEN, KA0IFG) Confirmed 6M addict: 6M WAS #1275, 6m VUCC #1260
