Does a repeater have the capibility to use CSQ for repeating... I know you can do it on direct but what about repeated? Thanks

wYtEbOyFoLyPh said:lol, so basically you're saying u cannot use CSQ on the new repeaters?
Actually, "duplex" is what a telephone uses - both open at the same time for live two way conversation; AKA "full duplex." "Duplex" in the radio world is a misnomer. The correct term should be "semi-duplex," because normally only one side of a conversation can be heard at one time; however, two channels are used, as you stated.KC8JPZ said:A duplex Repeater is a repeater that is operating on 2 frequencies. It receives on one of them and simultaneously transmits what it is receiving on the other frequency.[/url]
wYtEbOyFoLyPh said:OK, I guess I am confused. The only repeaters I know of are set up like this. Output 460.475 173.8 and Input 465.475 173.8. What would that be, duplex or simplex? If what I am hearing it right how can you TX on the same freq. you RX on?
This is duplex. This may be displayed in a frequency guide as "R" for "Repeater," "B" for "Base," or "D" for "Duplex."wYtEbOyFoLyPh said:The only repeaters I know of are set up like this. Output 460.475 173.8 and Input 465.475 173.8. What would that be, duplex or simplex?
Many radios are capable of switching from duplex to simplex. In that case, a user would switch to simplex and then the radio would be transmitting on the RX frequency. This is to avoid transmitting on the frequency that would activate the repeater (the input frequency). Radio users choose this option to use as talk around to other nearby users without hitting up the repeater and having the repeater retransmit their communications. Since the RX frequency is used, the user can still hear the transmissions from the repeater as well. This use of simplex does not interfere with the repeater and only transmits with the power output of the portable or mobile radio used. After the user is done with the simplex mode, the user switches the radio back to repeater mode and the radio now transmits on the input frequency, enabling communications with the repeater again. This is sometimes designated as a "TAC" or "Tacticle" channel. This may be displayed in a frequency guide as "S" for "Simplex," "M" for "Mobile," or without any designation (most of the time if there is no designation, the assumption is that the frequency is simplex).wYtEbOyFoLyPh said:If what I am hearing it right how can you TX on the same freq. you RX on?
wYtEbOyFoLyPh said:Thanks for your help guys, it's appreciated. One more thing than I'll shut up, heh. Some police dispatchers hit the repeater, while others don't. They always hit the repeater on TRS's tho. Does the TRS not have any other capability?
Because some run little base radios in the dispatch center so, from the system's view, they're the same as mobiles. Others are connected to the repeater by wire so you don't hear a "repeat".wYtEbOyFoLyPh said:Thanks for your help guys, it's appreciated. One more thing than I'll shut up, heh.

That's because a TRS is inherently a repeater system.They always hit the repeater on TRS's tho. Does the TRS not have any other capability?
