I have found feed keys a few times and then found the feed but after entering the keys I get audio only I am using my tm 5042 m3 ci i use 8280 on the remote when on the channel and enter the keys on a vacant line but s few times i have had audio only ,the format for the feed is 4-2-2 and does have cw before the keys so i don't know if that stands for crypto works and that i should enter the keys on a cw line using mute exit on the remote? can anyone help clear this up for me? maybe its audio only.
