I've moved the ROS RX up to 502.0 dial - so the RF is centered on 503.5 The MFSK is on 502.4 dial / 503.4 RF (1kHz AF) Hope this makes sense? Now I should be able to TX & RX in MFSK as well as RX in ROS, all within 100Hz of each other. Let's see what transpires - if someone wants to set up a ROS beacon... John GM4SLV
