I may need users willing to test a change to MMDVMHost. You should NOT be running Pi-Star and know how to compile MMDVMHost.

Steve, I am not aware of any other reflector with that many clients connected. Maybe a good test would be to try to see if we can get a large group connected on a different reflector and see if the issue follows. I have thought that the l# of clients connected just might have something to do with it. Just let me know If I can help the troubleshooting process in any way.

Can you or anyone else point to another reflector with 150+ connections? I have been told that NA TAC1 works great. That reflector is running the same binary on the same host. I listened to a conversation yesterday where 2 stations were complaining about about having problems hearing each other. I heard both station without a problem. Another local user listening on a Quantar reported having no problem listening to the conversation.

Re: P25 North America reflector

 

That’s partly why I stay parked on the Talkgroup all the time, and is why I created Facebook page and group to promote the Talkgroup, so that more use it and bring awareness that it’s there.  I want to see it succeed and work flawlessly like others do.  I love P25 and it’s purpose in ham radio.  Just like I switched to TGIF instead of BrandMeister.  Because I saw potential in it and all that use it.  Let’s work together like Robert said and let this Talkgroup shine!

Your traffic does not pass through any bridge. There are 150+ gateways connected. I have heard the complaint and if it's like yesterday, I could hear both sides of the QSO just fine. Please make sure your hotspot is adjusted correctly. There is quite a bit of data that passes through the host:

You can add M17 to a DVSwitch installation, but you have to use third
party software, and have an Analog_Reflector installation.  The software
is called USRP2M17.  It does have a couple of limitations:

1.  Currently, there is no way to easily initiate a connection to a
specific reflector on the fly, but USRP2M17 is good for linking to a
fixed reflector.

2.  USRP2M7 doesn't seem to recover from reflector or network outages
and needs to be restarted to reconnect.

Within those limitations, it works well.

Ideally, M17 support in Analog_Bridge would be nice, and I'd switch to
AB in a heartbeat, if M17 support is added.
