Initial setup of SunSDR2 Pro

To get the rig up and going it's not like most dial and knob rigs were you plug it in, turn it on and start spinning the VFO. This as most SDR rigs there has to be a talking relationship with the rig and PC. Lets start with the PC because there is going to be software on your PC that the SDR rig will have to communicate with and to do it well your PC should meet certain spec's.

Apache Labs ANAN 10 recommends an Intel i3 2ghz or better, 4 GB ram, screen resolution of 1280x1024 and a full duplex 1 GB ethernet card.

Flex radios knowledge base suggests Intel i3 or i5 quad core processor,  4GB ram for 32 bit OS and 8 GB ram for 64 bit OS, screen resolution of 1280x768 and the ability to support firewire. 

Sunsdr2 Pro recommends (located under "read it first") intel i3 1.6 ghz or higher, 8GB ram did not specify 32 or 64 bit OS, minimum screen resolution of 1024x600, LAN network card of 100 Mbps or 1 Gbps

Now mind you these in some cases are minimum specs but even to move up to the next level in a PC would not mean you are moving toward a high end gaming PC. Most of us have a PC at home for one reason or another and I would go out on a limb to say that most PC's at ham's homes would meet the minimum standard for SDR to function well. 
My SunSDR2 Pro's setup involves some minor PC techno wizbong maneuvering.......my SDR rig like most others communicate to the PC via a LAN cable and using an IP address. Now the Apache Labs ANAN 10 when powered on (if your LAN is correctly configured) an IP address should be automatically assigned in other words the rig and software should be communicating. The Flex radios are the same in regards to setup (again if your LAN is correctly configured) an IP address should be automatically assigned. This I believe is known as DHCP were the configuring is done automatically. For some reason the SunSDR2 Pro does not take advantage of this, you have to manually assign the IP address. It did not work out to well for me as I have 2 LAN options in my PC one is a card and the other is the one on the motherboard. When configuring the IP address I called up the wrong card (not the one the SDR rig was plugged into) Once I figured that out I was getting conflicts and issues. Long story short I have everything running now. I may email the Expert Electronics and ask why they chose this route and not DHCP.
The only (as far as I know) software this radio will work with is ExpertSDR software. Having said that I am very happy with the software and questions I have asked on the forum has been answered very promptly. It runs very smoothly on my PC and the waterfall looks great! The next post I will be looking at the ExpertSDR software.
