If you set up yer mobile to use chan A for input and chan B for output to and from your HT.
When you TX on the HT, you are ID'ng for the transmission on chan A
However when the repeater traffic comes back to you, your mobile is now sending it on chan B, not the repeater output, but the output of YOUR repeater.
I disagree with you.

Let's use real frequencies for demonstration purposes.

My HT is set to TX and RX on 444.00. The repeater input is on 145.00 input and 146.00 output. That means my crossband repeat rig is set on 444.00 on one band and 145.00/146.00 on the other band. When I key my HT and ID, it will be heard on 444.00. The crossband rig will hear it on 444.00 and tx it on 145.00. Now my ID has been heard on two frequencies I'm using. Then the repeater picks it up on 145.00 and sends it to the output on 146.00. Now my ID is on three frequencies. While I'm keying my HT my crossband repeat rig is busy RX on 144.00 and TX on 145.00 so it cannot also be RX on the repeater output of 146. When someone else talks back to me and IDs, my crossband rig hears 146.00 and sends it back to 444.00. Now their ID was heard on the repeater input of 145.00, the repeater output of 145.00 and my crossband/HT freq of 444.00. The other station I'm talking to has also now ID on all the frequencies they've talked on also. My ID doesn't have to come out of my crossband rig on 146.00 because I have never TX out of it on 146.00. It has, however come out of the repeater on 146.00 which is where it was broadcast from. It really doesn't make any difference, because I have fullfilled the requirement to ID on all frequencies I am using. The rules don't specify which rig has to do the ID'ing.

On your output, it is active any time there is traffic on the other system.
So what. Everyone IDs when they're supposed to and their ID is heard on all the frequencies in use. My id was heard on my output because that's also the same feq my HT is TX on, which I already ID'd on. There's no requirement that IDs are heard on every transmission, only every 10 minutes.

Quote:
You aren't IDng on that output frequency you are only heard with ID on the system you are linked to and on your input frequency.
The output of your crossband is still unidentified.
NO. The repeater broadcasts my ID on it's ouput, my crossbander broadcasts my ID on both of it's outputs, and my HT broadcasts my ID on it's output. Just because the other stations don't "hear" all the frequencies it's being TX on doesn't mean it's not being TX.

why not reverse and id, if you're x-banding into a repeater and using a ht most likely you can't hit the repeater with just the ht. so if you key and id on the repeaters output freq most likely nobody will hear it, but your x-bander will and tx it where previously unidentified.
As far as remote shut off, call the xyl and tell her to turn it off hi hi.

If you are using a Yaesu HT you might be able to use ARTS with auto ID, actually you could probably use it w/o a Yaesu HT just for ID but if you have a HT that supports ARTS than you can also tell if you go out of your CBR's range. I dont know if it will let you leave ARTS on and go into Xband repeat mode, but if it does that would take care of ID from repeater to you for duplex operation. Then as long as you ID when you talk through CBR you shoud be fine. If that doesnt work another choice is use your HT to transmit on repeater out freq and your CBR repeats call to the freq your using. I dont understand why they dont have more xband features on rigs that support it, it could all be added in software and would cost next to nothing for them to add it.

The newer firmwares have CWID now which solves the issue I was talking about.

When you full duplex crossband, the transmission of your crossbanding station back to your HT is not identified unless you have an IDer built into the crossbanding radio. They are fixing that now with the newer radios I've recently found out.

The simple fix for the older radios is to half-duplex the crossband, meaning you monitor the repeater output on the HT directly and don't re-transmit the repeater output via your crossband rig.

I think I stated it earlier in the thread or have said it before...just be sure if you crossband that you are using the proper band for your links and the proper frequencies. Waaaayyy too many people around here use 2m links and/or use frequencies allocated to simplex use or already in use as control links for existing repeaters. Some don't use PL enc/dec on their crossband either.

You must use the proper frequencies and by all means, use PL/CTCSS for full enc/dec on the crossband rig. Otherwise you stand to create a lot of interference and confusion.

This is the problem area. Only you can legally ID your cross band radio. You are the control operator. Your call sign must be heard per 97.119 (a) on all output frequencies of the cross banded radio.
