Issue when selecting DUPLEX modem

Post by N5BOC »

I am having trouble connecting to Brandmeister when I select the DUPLEX modem. It is almost as if my security password is not set. But if I incorrectly change it to a SIMPLEX modem, it works consistently. ( nothing changed in security settings )
So this brings me to a 2 pronged question.

#1: Anyone else had the problem I'm having when a DUPLEX modem is selected? I am not sure if this is Brandmeister only or does another network like TGIF have the same issue. ( I will do some work to access this )
#2: What exactly gets changed in Pi-Star when a modem is selected? I have my suspicion that selecting a modem just chooses some preset config settings for the MMDVMhost file. If this is correct I'd like to understand what is configured differently when jumping from SIMPLEX to DUPLEX modem. I am fairly sure the MMDVM board type ( SIMPLEX vs DUPLEX ) is in the header data sent to Brandmeister. I'm really hoping there isn't a problem at the server level and it locks me out if the word DUPLEX is in the header data.
