GRINS stands for the Gramin Radio Inter Networking System, Gram Vaani’s broadcast platform for community radio stations. We are very happy to announce that the first release is now available! You can download and use it free of cost. An open-source release will also be available in just a few weeks.
GRINS is an enhanced automation system for community radio stations. Built on Gram Vaani’s MINP platform, the current release of GRINS allows radio station operators to schedule broadcasts, preview programs, record live transmissions, and maintain an extensive semantically searchable library. In future releases, GRINS will be enhanced to handle telephony calls, sending and receiving SMS messages, and Internet connectivity to share and stream content with other GRINS deployments. Some of the key features of GRINS that distinguish it from other radio broadcast platforms are as follows:
- Commodity hardware: GRINS does most processing in software to eliminate the need of buying expensive audio hardware, and yet imposes very low processing overhead on the system. For this reason, GRINS can be run off commodity PCs and single board computers, significantly reducing the costs of setting up community radio stations.
- Service oriented design: All functionality provided by GRINS is handled by different services, such as the Audio Service for playout, Archiver Service for recording, Library Service for storage, etc. Each of these services can be run either on a single machine, or off multiple machines. This makes the deployment of GRINS extremely flexible to be able to fit into any kind of a radio station setup.
- Application development platform: The open API of GRINS allows third party developers to build their own radio applications using the various underlying services that GRINS provides. For example, you can build specific applications for the broadcast of educational programs or health programs, that allow quick search and playback features for the respective topics. In the future, once GRINS begins to support the telephone, video, and Internet planes, these applications can even be multiplanar in nature.
- Easy to use UI: The GRINS user interface has been especially designed keeping in mind the target population of rural areas in India and other developing countries. The use of large icons and simple navigation makes GRINS easy to use even for radio operators who are new to computerized systems.
- Diagnostics: A key feature of GRINS, the system can actually detect any network faults or audio cable errors or poor audio quality through Digital Signal Processing (DSP), and guide the operators on how to fix the problem locally. This reduces the down-time of the system so that radio stations located in remote rural areas do not have to wait for a technician to visit them and fix small problems.

In just a few weeks, we will do out first pilot with Radio Bundelkhand, the community radio station in Orcha, MP set up by Development Alternatives.

Dear Sir,
We have developed low-cost FM Transmission equipment for deployment of Low-power FM tranmitters.
Presently, we have technology & prototypes for 10-15 watts FM transmitters, and are looking for opportunities in this new field.
You may also note that, the coverage is limited by the geographical area & the obstacles therein, and the coverage is limited by some factors - height of antenna, gain of antenna, low-loss RF cables.
The reception can however be extended by using external antennas connected the radio reciever. This can have provide extended coverage, and low-cost solar powered FM radios with external antenna can be developed using existing H/W.
This might mean, that if a 100 watt/50 watt FM tranmitter has a coverage of 10 Kms with regular radio recievers. This newly radio receivers may provide coverage of 25-30 Kms, with a 10 Watt FM transmitter.
The coverage is proportional to the Log (power output) due to certain constraints. Therefore, a 10 watt FM station shall have approx. half the coverage of a 100 watt FM station. This translates into lower operational cost & sustainability in remote areas, with power coming from smaller solar panels for 24×7 operation.
Thank you.
Dr. R.S. Malik
Dear Dr. Malik,
We would very much like to know more about your system. We are currently not working on the transmitter end, and this could possibly be a good collaboration.
