I have for sale an INRAD #103 400hz CW filter for the 8.83 mhz IF, and a Kenwood YG455CN-1 270hz CW filter for the 455khz IF. These fit the TS450/690/850/930/940/950 and the INRAD will also fit in the TS570. I am asking $80 each shipped. 73s John AA5JG (ex: W5TD, NE0P, N0EEN, KA0IFG) Confirmed 6M addict: 6M WAS #1275, 6m VUCC #1260
