If you have define the time slot with the channel, is it then necessary to create separate channels for TS1 and for TS2, so you're covered for each possibility? I don't know which TG or TS I might be on at any given time and if I don't have both time slots, I might just go out of range and be unable to roam, no? -- In other words, if I only program a roaming channel for TS1 and I'm on a TS2 group, then I'm out of luck, correct? -- Also, what happens if I'm on a Brandmeister repeater, for instance, and I'm monitoring TG 3104 and I roam to another repeater that carries that TG on a different timeslot? Would my roaming not work?
Hi! We invite you to ask your question in our very large Facebook group. Here's the link to join: facebook.com/groups/BridgeComSystems. Also, you might want to check out our plug-and-play package at this link: www.bridgecomsystems.com/pages/plug-and-play-package.
This question may have already been answered but, if you have to define the roaming zone in the optional settings, does that mean that your radio can only roam one zone while in operation? (eg) if I were driving to Texas from Canada, there are several zones I'd like to set up and I'd like to be able to cycle through them as I go without re-programming. Hope I made myself clear, I'm still quite new to this. ALSO, thanks for this video, it is really great!
Re; my zumspot. I set a uhf frequency when I configured my pi-Star dashboard. Is that related to roaming? I can’t get my radio to connect to mynzumspot. Thx Kd7ktv
Roaming you have multiple DMR repeaters set up in memory that you're driving between them and if it can't keep up your local repeater in the link, it'll then try to keep the next one basically scanning between repeaters until it finds one
Keying up repeaters unnecessarily using roaming can get you banned on a repeater or network. Radio only needs to key-up or query repeater if the repeater owner does not enable the DMR beacon in the repeater. If you constantly key repeaters, the owner may disable/kill your DMR radio over-the-air, kill your pets, and/or you :) _________ How roaming is supposed to work: If enabled, repeater beacons every NNN seconds for about XXX seconds (could be anything; set by owner or amateur club/group), in northern California USA, its 100 seconds/8 seconds) You enable roaming on a physical channel position, and tell it which Roam List (set of repeaters) to use. From power-up, radio listens for a DMR signal on its starting channel for exactly 100 seconds (must match repeater beacon occurrence setting) If it hears a DMR signal (beacon or voice activity) meeting the minimum signal threshold you set, it stays there and resets its roam timer (and keeps doing this as long as signal meets the dBm threshold (mobile: usually between -100 to -92 dBm, and 5W portables are always set for a signal about 8 dB stronger than a mobile's setting, -92 to -84 dBm). But this is set depending on repeater system design and location....experiment. If it doesn't hear activity or beacon in that period, it starts stepping through each channel in the roam list *listening* for a signal meeting the roaming threshold; it may do this forever. Once it finds one, it stops there, resetting its roaming timer. ______________________ Important: Notice that the radio **never transmits** or queries above. This is good. If it keeps transmitting, it may keep a repeater keyed indefinitely or result in endless kerchunking and steal a slot away from other users. There is an additional feature called "Active Site Roam" or whatever the radio manufacturer calls it. In this case, on the last step above, if the radio fails to hear anything after so much time, it will automatically and sequentially kerchunk each repeater in the roam list until it finds one meeting the minimum signal threshold. This is just fine. When would you enable this? Only when the repeaters in your roam list are not configured to transmit a beacon by the repeater owner. To find out if a repeater is sending a beacon, listen to it in analog mode and check for recurring transmissions that have the same modulation sound. Measure the number of seconds or minutes between each (start to start) and use that value for the beacon occurrence setting).
Postscript: I have subsequently found out that the 'keying up' method of roaming, as used by Anytone radios, does not key up the other out of range IP connected repeaters and, apparently, does not fully open up the repeater being tested by this method of RSSI testing. Personally, I feel this is a cheap and cheerful way of roaming and the beacon RSSI method is much more elegant and, potentially, more transparent. The Anytone system has the advantage of being compatible with both repeaters that send out beacons - and those that don't. (Some repeaters do not send out beacons....)
Great job! I used this video to set up and successfully test roaming on my Anytone 878 and will create a companion video to this one. Thank you Duane.
Mine won’t roam when I TX on a out of range repeater. Followed this video and yours. What am I missing?

Thanks but curious on how is this checking for a repeater? Is it kerchunking it?
No: the radio listens for the repeated silent periodic digital beacon sent out by the repeater

This works with the Alinco DJ-MD5X to,
Thank you for your comment!
Awesome! Thanks for sharing
How do you choose which talkgroup and timeslot?
The host organizations of the DMR repeaters typically publish the freq, color and timeslot used.
@@branvinivideo I think he means in the CPS itself....
@@billoscroft8119 His question was from 2yrs ago… 😂
@@branvinivideo I know....but he will still see my reply and, who knows, he may still be wondering....
I'm still curious about the talkgroup part...

s you say, if this radio operates in the same way as commercial roaming, the radio does >>not
@@billoscroft8119 yes that is how it works for DMR repeaters

Funny!! Nothing was ever mention about APRS. This is the wrong video
