Mmdvm hs hat duplex shield setting up

Post by GW7IRV »

Hi

I am not sure on how.to set up duplex shield on pi- star and md380!

Has anyone out there got there's working and if so can you please help me because I'm at a loss!

I have the pistar up and running on my rpi, NOGSG contact manager as codeplug for cps md380 software on my md380.

Do i need duplex setting on pi-star rather than simplex and what frequencies are rx and tx same and if not is it 500kHz or 5mhz offset.?

Is duplex set to .5 in expert mode as it says it's half duplex on hotspot!I

Is it ok to use simplex channel on md380?

I think that about covers it!

Any guidance would be most appreciated!

For a kickoff, i can sent you mine working config file.
To progam the freq. for the 380 you have to switch the rx/tx frequenties.
Use brandmeiste selfcare for add static goeps, mine is 7 digits plus example 07 . totaloly 9digits!
in brandmeister you can set know static tg in 1 as 2.the.
Make a new codeplug and use port 1 or 2.
If this is enough info. ok. Otherwise i will help you till it works, "73 Guus PA3HAS

Hi Guus

Sorry to being a pain but I still don't understand what to do!

Your config might be the answer

I am a newbie and logged on to brandmieser but none the wiser!

I can receive calls when in simplex channel on my NOGSG codeplug on md380 though, is this a step in the right direction and this step is as far i can manage so far!

Any further help appreciated.
