HT not TXing into openspot1

Hello, I cannot get my new AT-D787UV+ to be heard on my openspot1.
My call does not show up in the status list.
The modem led does not flash when I Tx.
I'm using a buddy's codeplug and my radio worked fine thru his mobile hotspot in his car.

Could someone please point me in the right direction.
Thanks, Dave N3DZ

There's a color code or frequency mismatch. If you've verified that they are set correctly both in your openSPOT and your transceiver, but it still does not work, then do a DMR AutoCal, or manually change the DMR demod mode on the Modem page for the lowest BER.

Thanks for the response.

Tx and Rx frequencies are all the same in the radio and openspot1.

Color code is 1 on both also.

DMR AutoCal does not work. I tried all 6 modes (after save) and the modem led still did not light up.

I read people talking about Talk Around - do I need that checked in the CPS?

Please make sure both RX and TX frequency is the same, and it is in the 70cm band, and in the OS1's supported freq. range. Talk around setting is not doing anything on simplex channels.

Yes, both RX and TX frequency is the same, and it is in the 70cm band, and in the OS1's supported freq. range. Still when I press PTT the modem led does not light up at all. And I don't see my callsign on the Status page. Dave N3DZ

- Try resetting the modem configuration with the button at the bottom of the Modem page, and then reconfigure the modem mode to DMR hotspot
- Try changing both RX and TX frequencies
- Make sure your openSPOT1 is updated to the latest stable firmware
