Alinco DX-SR9 Hybrid SDR Transceiver Review
First of all remember that the Alinco DX-SR9 is a budget transceiver with SDR capability. It doesn’t have all the bells and whistles of it’s more expensive competition. However the DX-SR9 appears to be a very decent rig all on it’s own. SDR capability and SDR Software allows the DX-SR9 to come closer in performance to it’s more expensive competition costing up 2 to 3 times as much. The KGTRX software is a pretty good program to use with the DX-SR9 out of the box and seems to be pretty reliable. So, at the end of the day the DX-SR9 is an excellent little rig for hams that would like to experiment with SDR at a low cost. It’s a very easy rig to use when combined with the KGTRX. Even though a few small issues were mentioned, they are by no means show stoppers at this price level. They may be possibly improved with future firmware updates since the DX-SR9 is a relatively new rig in Alinco’s lineup. The DX-SR9 represents an excellent value as a 100 Watt SDR capable transceiver. Frankly at the ~$750 street price point it has no real competition in the 100 watt category. Maybe this will encourage some of the other manufacturers to get with the program and start adding SDR capability to their rigs instead of just a remix of the same old technology.
DX-SR9 OmniRig .INI File
This is the Beta OmniRig .ini file. The .ini file only supports a small subset of the DX-SR9 command structure. The supported features are read / write the VFO frequency, read / write the Mode, toggle TRX and toggle RCV. This is usually what most external OmniRig comaptible programs use. However, other commands can be added that are supported by the DX-SR9 and can be added if needed by editing the .ini file. To use, download the DX-SR9_Beta.ini file below and then download OmniRig. Install OmniRig and then place the .ini file in the Rigs folder in the OmniRig directory. Open OmniRig and select the DX-SR9_Beta file for Rig1. Set the port to your ERW-7’s serial port number. The communications settings should be 9600,N,1. You might want to try setting the Polling Time to 100 and the Timeout to 100 to start with. Some programs may briefly flash “rig not active” on a regular basis, but this is usually not a problem. The download of the Beta OmniRig .ini file can be found in the HRS Alinco forum at the link below. Please post any questions or issues to the forum.
