Afedri SDR-Net 2.3a Review
the the Control Box Software to a folder and start the SDR_Control.exe program. You should see the Control Box software startup and and check the following items:
- Select the Network Tab
- Enter the new unused default IP address compatible with your router in the SDR IP Address box.
- Check that the SDR IP Mask setting is appropriate for your network. If not change it. (probably not necessary for most networks)
- Go ahead and assign a Gateway IP address that falls within your routers IP range.
- It is not necessary change the Destination IP address (not user selectable). Don’t change the port setting since most SDR programs look for IP activity on this port number.
- If you want to be able to use the Afedri SDR-Nets full Lan bandwidth check that the Network Sample Rate is set to 1333333.
- Click the Save button and shut down the Control Box software.
- Connect a standard Lan cable between the router and the Afedri Net-SDR.
- Restart the Control Box software, if you were successful, you should see a green light by the Afedri SDR Network label and the FE label.
- You can keep the USB cable plugged in for power if you wish or use another source of power.
- Check the Enable Network Interface box and the network interface should now be active.
- If you run into problems, one thing to check is to see if your router is blocking port 50000. Most routers will allow you to open a port for traffic, but you will have to do a little research on how to do that on your own particular router.
Ok, if all that went well, you can now start. SDR-Radio.com, but this time select Afedri SDR – (Lan). Again have SDR-Radio.com search for the Afedri SDR-Net. If all goes well, you should see the Afedri SDR-Net Lan listed. When you start this configuration the displayed bandwidth should be about 1225KHz (nice). This should for example allow you to easily monitor the activity of say the entire 20 Meter amateur radio band plus some.
Connecting the Afedri SDR-Net via also offers other advantages besides the expanded bandwidth. As we mentioned earlier, the Lan connection will allow other computers on your local area network to use the Afedri SDR-Net. SDR Radio.com will even let you share the Afedri SDR-Net with other SDR Radio.com users around the world by setting up a SDR server. You can also place the Afedri SDR-Net in a remote location and access it via the network. Another advantage is by using a long piece of ethernet cable and a USB power supply, you can move the Afedri SDR-Net closer to your antenna connection and away from your RF generating computer for quieter operation. You can also connect the Afedri Net-SDR to a Wireless Bridge and eliminate the ethernet cable if you want to. Just be sure you are using a robust wireless network.
Using the Afedri SDR-Net with other SDR Software
The Afedri SDR-Net will also work with popular SDR radio Software that is ExtIO friendly. We used the Afedri SDR-Net with HDSDR and Studio1 without any issues. To use these programs, you have to set up the Afedri SDR-Net a little differently. Programs such as HDSDR and Studio1 require you to install the Control Box software into their program directory. The simplest way to accomplish this is by just copying all the files that are provided in the Control Box folder to the HDSDR or Studio1 program directory. When you start the SDR program, the Control Box application should start along with it. The SDR software will control the tuning and decoding of the IQ signals. The Control Box software allows you to set other settings unique to the Afedri SDR-Net such as the FE Gain and VGA Gain controls which may be necessary to tweak the Afedri SDR-Net to perform best for your antenna and location. Normally when using HDSDR or Studio1, the gain controls are probably all you will need to adjust.
The Afedri SDR-Net Control Box
The Afedri SDR-Net Control box deserves a mention all on its own. First of all, kudos to Alex for designing such a nice looking interface. Most SDR utility
programs look just utilitarian. Alex did a great job of making the Control Box look attractive, if it has to be on your computer screen. However, the Control Box is more than just a pretty face. As mentioned above, one of the functions of the Control Box is to provide an interface between the Afedri SDR-Net and ExtIO enabled SDR programs. However, the Control Box can be used as a standalone tuning control for your SDR software if you wish. Also for SDR software that does not support ExtIO interfaces, you could use the Control Box to set the center frequency for the program. More than likely you will be using the Afedri SDR-Net with SDR programs that do support ExtIO and the Control Box can be placed in the background. However, the Control Box is still an important part of the Afedri SDR-Net when being used with ExtIO enabled programs because it lets you set the FE Gain and VGA Gain of the Afedri SDR-Net. If you are going to be using the Afedri SDR-Net on a Lan, you will also want to take a look at the Network section of the Control Box. As mentioned above, this is where you can customize network settings to better suit your own Lan environment. The Command Shell area is where you can change some of the more advanced settings of the Afedri SDR-Net. You probably should not change anything here, unless you seriously know what you are doing. The Dual Channel Rx is only functional with the new dual channel Afedri SDR-Net. The About section allows you to put the Afedri SDR-Net into mode to allow for firmware upgrades.
