Hi Geoff,

Well we managed to swap out the EPROM in VK2JPJ-1 this afternoon and
give the system a health check.
 
The digi is now VK2US-1 and fully supports the New-N, which means that
the TRACEn-N paths no longer work.
 
Unfortunately it looks like we did something to the system whilst
putting it all back in the cabinet and it APPEARS that whilst it is
receiving, the Transmit leg from the digi is not real hot.   Listening
to it on the drive home it sounds to be slightly over-deviating, which
is causing problematic decode by the other digis and even the IGate.
Potentially the TX Level pot in the TNC got bumped up whilst swapping
the EPROM.
 
I'll be checking things out remotely tonight to try and diagnose the
problem remotely, and we'll need to arrange another site visit to get it
all back into working order.
 
Apologies for killing the main Sydney digi :-( as it does drastically
affect the coverage around Sydney without it.
 
Hopefully something very minor and can be fixed in the very near future.
 
Geoff  VK2XJG
