Obico WNYO RF 16 move to Grand Island with a directional antenna actually would have resulted in less interference to RF 16 Woodstock.WNYO current tower is using an Omni pattern and is on much higher ground.My understanding is CITY Woodstock has to apply to stay on Rf 31 and accept no protection.I do see the transition phases for City-DT2 Woodstock and WNED are not same time.Maybe they will change to RF 16 at a later date.
