XPR6100 DMR programming question

I have programmed another agencies dispatch channel into my radio. I currently have RX only checked. My question is if I uncheck RX only will the radio transmit or make its presence known on the system? I also have ARS checked as disabled.

Thanks

If it's analog, it should only allow the transmission on whatever frequency is specified.
If it's trunking then your radio would have already affiliated with the network regardless of whether you have RX only checked or not.

Perhaps provide an additional "oops" failsafe by entering one of YOUR authorized simplex frequencies (or other system channel of YOURS) for transmit, even when you have checked it as "rx only".

This is a secondary catch in case you accidently uncheck it down the line and not notice it when dog-tired etc. Not likely to happen, but it costs nothing to do.

I'm not sure how this question differs from the last question? The answer is still no.
Ok thanks. Well the reason it differs from the last question is that in this scenario the channel is not set to RX only. I think this makes it clear then that as long as ARS is disabled then nothing is going to be transmitted unless PTT is pressed.

Not true. Radio sends periodic messages to the system in RX only is not checked. Depending on type and distance from site, they most consist of wakeup messages to repeaters. TT

It checks in on IPSC, Cap Plus, LCP, and Connect Plus. I think is also does it in conventional as well, but I have limited experience with that configuration. TT

So you are saying that the IPSC radios never transmit unless the operator hits the PTT button (or some other data is enabled in the radios)? I have been working with TRBO for 11 years and happen to work on TRBO systems everyday. If your radios are not transmitting, then you have a problem. TT

That’s exactly what I’m saying. Who are they going to affiliate with? There is no controller in an IPSC system.

My friend, you should brush up with the System Planner! The radios send our periodic "Wake Up" messages to the repeater to make sure it is still "Alive," especially if it has not heard from said repeater in a defined window. It also sends out "Wake Up" messages to repeaters in its Roam List in order to command them to keyup up in order to assess RSSI level. TT

How is the subscriber radio going to find out which site to connect to if it doesn't know which one is the closest? It needs to find the strength of each site by telling the repeater to transmit a burst and the radio assesses that to connect to the right site seamlessly.
