I have for sale an Icom FL101 250hz CW filter which fits many Icom radios including the 706/725/726/728/729/736/737/738/746/756/761/765/775 and maybe a few others. This filter is for the 9mhz IF and makes a huge difference on receive for CW and the digital modes. I am asking $65 shipped in the US and can take paypal/check/MO. 73 John AF5CC
