I have 2-tone signaling setup on the NX-5000 and NX-3000 and I'm trying to replicate this same configuration on the NX-1000.. however the NX-1000 only seems to support "NXDN ID" as an optional signaling type where as you can select 2-tone X on the NX-3000/5000. Is there another way I can setup alert tones to be cross compatible on all 3 series of radios? Essentially I'm just looking to setup an on-demand alert call that all users on the channel can hear to bring their attention to the channel. I'd like to do this on the NX-P500 as well but I'm not sure any of this will be supported there.
