The UK BrandMeister server uses the password "passw1rd" (without the quotation marks). The rest of the world uses the password "passw0rd". Keep in mind that if you have turned on hotspot security on your BrandMeister SelfCare at

, then you have to use the password you've set there.
Do you try to call openSPOT's built-in local echo on DMR ID 9999? It does not matter if you call this with a private or group call, however, the BM parrot on DMR ID 9990 only works with a private call, and some servers use different DMR IDs for the parrot service.
You should set the TX contact to the talkgroup you want to talk on.
Also you need to create an RX group list in your radio with TG9 in it, and assign this RX group list to all channels you want to use with the openSPOT. This way you'll be able to hear calls coming to TG9 regardless of what the current channel's TX contact is. This is important because openSPOT sends voice announcements to TG9.
