As we all known, many analog repeaters have their own frequency and CTCSS Tone, and the frequency maybe always the one many people already remembered, but not the CTCSS/DCS tone. So now, if your radio can scan for a CTCSS/DCS tone, that will be very useful. Today, let us see the CTCSS/DCS scanning on Retevis RT85.
The CTCSS/DCS scan can be use on VFO and channel mode. and their should have a CTCSS.DCS tone active for the current VFO or channel mode.
1. Press the F button to find the menu 29" SEEK", it will broadcast "scan CTCSS".
2. Press the F button again, it will begin to scan the CTCSS/DCS, when there is a signal, it will stop scanning. and if the signal disappear, it will scan again automatically, until you save this CTCSS/DCS for this current VFO/channel.
