[App_rpt-users] Dual Mode (DV and FM) systems go-live

[Ramesh Dhami (VA3UV)]

Hi All;

After months of development / testing and challenges with my repeater 
site <G>, we now have two fully functional / automatic D-STAR compatible 
and FM (app_rpt enabled) repeaters on-the-air in the Greater Toronto Area.

The repeaters both use commercial grade FM repeaters.  The 
auto-switching between FM and DV is managed by an external multiplexer 
that Jon (VA3RQ) and I designed.  In the case of repeaters that have two 
audio inputs (TXA and TD), the multiplexer allows for the switching of 
audio between these 2 inputs (FM audio into the TXA input and D-STAR 
'data' into the TD input).  For repeaters that have only one audio 
input, the Multiplexer caters for this case too.

Please contact me off-list for further details.  Just for the record, we 
are not selling the Multiplexer, it is an open source project, the 
schematic is available, you build it, you get to enjoy it :).

Cheers!

Ramesh.
