Radioddity DMR Radio Programming

[Squad101]

I have a GD-73A I am programming for work. We have Motorola XPR but not enough to go around.
We have One Frequency and two talk groups. TG:1 Slot:1 is Operations TG:2 Slot:2 is maintenance
When I transmit it some times takes a while before I hear voice out of my radio scanner but it says it’s transmitting and some times I get a data noise, and When I transmit on TG2 Slot 2 it uses Slot1 even though it’s programmed for slot 2.
Anyone know what I’m doing wrong?

I'm afraid that I can't offer much help as I am not familiar with that model. All I could suggest is to double-check all of your CPS entries (and keep your channels as "clean" as possible (few options).

I started from scratch and kept it clean as possible. I can hear ops on slot 1 and maintenance on slot 2. No crossover when both TG are being used at the same time. I’m just having this TX issue.

You would likely have to post the codeplug for someone to take a look at.

Post it to where?
Would the RX frequency be different than the TX Frequency? If so how would I find the TX Frequency?

If you don't have a repeater, the frequencies will likely be the same (simplex). Simplex DMR works differently than through a repeater and it is possible to hear it on either time slot.

In my CPS, I need to have talkgroups entered in contacts as group call, and in my RX group list and in my TX Contacts for each channel. Don't know your radio or CPS and how those names correspond. I'm sure you already have the correct color code.

The more I reading I’m starting to think there is a repeater. I remember one time I tried to tx from off site and it wouldn’t let me as if I was out of range.

If you're operating with a UHF repeater, the frequencies are usually 5 MHz apart (ie 460.xxx outbound and 465.xxx inbound, as one example). If the repeater is VHF, there is no standard separation and you'll have to research the inbound frequency.

Certainly sounds like you are on a repeater then. You obviously know your RX frequency, so you could look that up in the FCC database, perhaps find your callsign then look for another frequency associated to it. As already mentioned it would typically be 5 mhz above or below for UHF.

Another option is to use a dongle with SDR#, FMP24 whatever that lets you view the spectrum. Key up one of the Moto radios and watch for the spike... that'll be your TX frequency. Even if you are out of range you'll still see a brief transmission as it tries to reach out to the repeater.

And of course it goes without saying... be careful playing around on a system that isn't yours with unapproved radios!

Thanks. It’s programmed correctly. Not sure why my scanner was giving me false info. The Moto XPRs we have received it just fine and vice verse.
