That sounds like its a radio programming issue. Wrong DMR ID, wrong CC, wrong offset.

That isn't going to fix anything, just toggle the mode on and off. You've got to figure out your incorrect setting.

Its not odd at all, its comparing apples and oranges. What you've shown is HT operates, but there are a number of things that have to be in alignment for it to work correctly using a hotspot. Make sure DMR ID matches what is programmed in your hotspot. It won't respond to a different DMR ID unless you set the hotspot to public. Check the CC, check to make sure that it is transmitting on the hotspots receive frequency, and receiving on the hotspots transmitting frequency. Adjust the offset.
Rx on the radio = Tx on the hotspot = 439.55
Tx on the radio= Rx on the Hotspot = 431.95
CC = 1 on both
Slot = 1 on radio, both enabled on hotspot
Offset is disabled on radio as Rx/Tx are set
Radio ID is same as hotspot.
Radio is a Baofeng RD-5R

That is a very weird offset selection. In the US we use a 5Mhz shift up or down depending on the frequency.

That is not the offset you need to adjust.

Don't just say it matches, DOUBLE CHECK IT. You could have a typo.
I did double check it.
You skipped another question again.

Have you used MMDVMCal and PROPERLY set the offset?? Every radio that is manufactured has an allowed tolerance for being off frequency. If you haven't tuned it then it could be so far off frequency that it isn't recognized.

Run MMDVMCal.
I ran it,I got no response. I'll try it again.

I ran MMDVMCAL again. Once again I got no response when keying up the DMR radio. but I was able to get a response when keying the YSF radio. I put the offset I got from there into the Modem configuration, which has certainly improved my YSF transmissions, but done nothing for DMR

I'm away now, it's getting late here in the land of Heidi. I'll catch up with any replies in the morning.

This is bizarre. Just after my last post I disabled YSF and everything started working - sort of. The hotspot remains in listen mode, I can Tx and Rx from the Parrot without problem. I tried a talk group and seems as though I can be heard, but I can't hear any replies. When my buddy in the UK is up I'll try a private conversation with him.

Sit rep:

* handheld radio now talks to hotspot (Trx box show listening, responds to keydown)
* I can connect to Parrot and get a reply, both the the TG (9990) and via direct dial to 228997
* Connections to the Hotspot show up in the Brandmeister Last Heard list
* I cannot Tx or Rx with my friend in the UK, either directly or within a TG

If it weren't for the Parrot response and the fact that I show up in Last Heard I would suspect a network problem.

Must be. I’ll look again at the radio programming. Thanks for all the help.

We were troubleshooting via phone, so he was calling but I wasn’t receiving and vice versa.

Even if the offset needs setting, surely the dashboard would indicate that the hat is listening?
Yes, picture.
Update:
Just saw the model on the seller's web.

Dashboard WON'T show RF activity if OFFSET is wrong 'cause 7021 will be NOT receiving properly the RD5R signal.

YSF may eventually work even having OFFSETs on wrong values.
