And it occurred to me that one could build an entire 10GHz transceiver without requiring any special tools or test equipment: just a few parts that are easily available on ebay. Note that the master clock rate must be an integer multiple of the sampling rate. The Universal Software Radio Peripheral (USRP) devices are software defined radios that you can use in a variety of . What's nice about srsLTE is that it has a built-in script that allows this interface to route out to your eth0 or eno1 interface, which is usually your primary Internet access. The key is that the LO and IF ports should have a range that covers 5.0 to 5.2 GHz and the RF port needs to cover 10GHz. [1]The RJ45 port is used for remote management of the device and does not support IQ streaming. SoDa Radio was originally written to provide a VHF/UHF exciter/IF strip for a 10GHz system based on the Down East Microwave 10GHz transverter, a DEMI low noise amplifier, and a surplus power amplifier. The three most important files to get a system up and running are the enb.conf, epc.conf, and users.db. This is optional, but it will make your system much less prone to receive sample over- or transmit sample underruns. connectedRadios = findsdru; addressRX = '30AC288'; platformRX = 'B210'; Fig. I'd spent several years building that system, and had amassed a number of pieces of test equipment, parts, tools, and widgets. 30 secs. Expert users might have cases where a more fine-grained control over the resampling stages is required, in which case manually selecting a master clock rate might be more suitable than the automatic rate. On the other hand, it works and it is quite simple. Quite a capable little radio for not a whole lot of investment. Use a semicolon to separate the entriesfor. If you have a rudimentary set of garage tools and a few band-aids around, you could even build your own horn from the directions found in W1GHZ's Antenna Book. Paul also shows how to build a coax-to-waveguide transition here (with an erratum here). 2: Block Diagram of GRC used for PSK Transmission Random source generates 0's and 1's which are converted to float.
