I have for sale the Icom UT-106 DSP board which adds noise reduction and an autonotch filter function to such radios as the Icom 718, 706MKII, 910H, and R2500 and R75 receivers. It is functioning fine and is no longer available from most dealers. - I am asking $100 shipped and can take paypal/check/MO. - 73 John AF5CC
