Genesis SDR Setup for Digital modes (Asus Xonar D1)

Creative Audigy SE was my first choice for 96kHz capable SDR sound card. Price was very good but a quality was very discussable. One shared line in, problem with I/Q correction, random change of I and Q channel at line in.... It was a time to find a better card. I start to looking for something that will be under 100 and that will fit in PCI slot at my PC, and in my budget to ( I give up of USB sound cards and laptop combination for good).

At my surprise, if I eliminate bottom level Creative models (like my old Audigy), I found only two sound cards under 100 , Asus DS for about 40 and Asus D1 for about 60. Asus D1 specs was impressive but only one shared line/mic input ?! I had no better choice so, I decided to risk 60 for D1. After 3 months of intensive usage with my G59, I can tell that I made a good decision. Original ASIO drivers, superb specs, 24bit/96kHz(192kHz), no problems with I/Q correction, very ease to install and setup... Only bad side is just one shared line/mic input, but this is disadvantage only if you plan to use your G59 as SSB phone rig. In that case you can use another (maybe motherboard integrated) sound card for voice processing. For about 60 this card is best possible solution!

 

From Setup menu select General card and set options like on picture. Set G59 as a radio model and PA10 unit if you have one.

 

In setup menu choose audio settings and set "Unsupported sound card". Asus Xonar D1 is full ASIO compatible sound card so set ASIO drivers. You can use MIME drivers also but ASIO is best solution for this sound card. Check pictures below and compare latency time at least. Forget about I/Q correction and set "Sample rate" to 96kHz. You can try with 192kHz sample rate but G59 filters will cut some of specter at sides of waterfall screen. Play little bit with latency settings to find optimal value for your card and computer.

For transferring sound from Genesis SDR to digital modes software is necessary to set Virtual Audio Cable support. In Audio/VAC menu enable VAC and set a pair of Virtual cables that you created as shown before. You can play with Sample rate to choose best audio. In my case it was 48000 but 22050 or 44100 should be good to. If you need VAC only for digital modes you can auto enable VAC for this modes and disable for others by setting this option. In my case, I use USB for digital modes so I leave this option unchecked. BTW, If I set DIGU or DIGL (at a main screen) for digital modes, I got a one or two seconds "delayed" RX/TX switching ?! Maybe someone know what I need to change to get non delayed RX/TX switching ?

 

This part is essential for paring Genesis SDR with other HAM radio software. If you install and set Virtal Com ports as I explain before, choose COM17 for CAT control and COM16 and RTS line for PTT control. Set CAT ID according your CAT software. I use Hamradio Deluxe/DM780 with native support for CAT control SDR-1000, so I just choose SDR-1000 from this menu. In some cases, like MIXW, you maybe need to set some of Kenwood models. Note: do not set COM6 and COM7! Some of digital mode software could not be set to use high values of serial port number like COM16 or COM17! So, reserve low serial port numbers for digital modes software and high serial port numbers for Genesis SDR.

 

Full working Genesis SDR should look like this. Note green USB field that indicate regular USB connection to PC.
