Guidelines for Community Radio Support Scheme (CRSS)
1.
BACKGROUND:
1.1
Community Radios in India were started after the first policy for Community
Radios was approved in the year 2002. This policy allowed only Educational
Institutions to set up Community Radios. This policy was broad-based in 2006 when
gross-roots organizations like NGOs and other Not-for-Profit organizations were also
allowed to set up Community Radios in India. This policy brought a paradigm shift in
the Community Radio Movement in the country. The Community Radios in the
country have grown from strength to strength. Today, India has 163 functional
Community Radio Stations and about 250 stations are in the pipeline.
1.2
The Community Radio sector reaches those who do not have access to media
infrastructure, or access and participation in the production of content. There is a need
to provide greater push to this Scheme as Community Radios have the potential to
strengthen people‟s perception in the development programmes. In a country like
India, where every State has its own language and cultural identity, Community Radios
also act as a repository of local folks, music and cultural heritage.
1.3
In spite of several efforts to streamline the permission process, the growth of
Community Radios in the country has somewhat remained moderate. The number of
operational Community Radio Stations (CRS) in India at present is rather
disappointing keeping in view its size and population. One reason for the slow growth
in this sector can be attributed to lack of resources with Non-Government
Organizations to meet the capital cost of setting up CRS and hand holding. Their
capacity to mobilize resources is extremely limited. It is perhaps time to think of a
mechanism to channelize financial assistance to genuine grass roots organizations to
enable them set up CRS.
1.4
So far, there was no scheme of the Government to fund CRS for capital or
operating expenses. However UNICEF and UNESCO have supported selected
organizations in the recent past to meet the capital cost of the equipment and the
machinery. Funds have also been provided to meet the running expenditure. However
most of this funding has been in the form of pilots and demonstration.
1.5
The problem of lack of financial resources for CRS exists not only in India but
world over. Therefore in order to ensure that genuine community voices are heard and
supported many countries around the world have set up Community Radio Funds to
support CRS.
1.6
Therefore, in the 12th Plan Government has introduced a new scheme namely
“Supporting Community Radio Movement in India” for providing financial assistance to
Community Radio Stations under the component “Community Radio Support Scheme”
(CRSS).

OBJECTIVES OF THE SCHEME
(i)
To strengthen new and existing CR Stations with resources, capacity and
technology so that they could provide access and voice to marginalized
communities.
(ii) To promote growth of CRS, especially in remote and rural areas, so that
people living in these areas could have access to a meaningful medium of
broadcast
(iii) To promote socio-economic and cultural development of communities as
CRS is a powerful medium for social mobilization
3.
SERVICES:
Grants under CRSS would broadly cover following areas:
a) Equipment Acquisition: - capital expenditure for purchase of equipments/up
gradation of equipments.
b) Training Support: - In order to access training processes and facilities, to
build community capacity to produce content and to manage the CR process
on their own.
c) Emergency Grants: - To cover damages and repairs faced by community
radio stations in extreme emergency situations like natural calamities,
lightning, cyclone, etc.
d) Replacement of existing equipment/ upgradation/ expansion as a one-time
cost for existing (on-air) stations.
e) Innovative grants: In order to support the community radio sector and
encourage innovation in CR technology, content development, research,
evaluation methodology development and training processes etc.
4.
TECHNICAL SPECIFICATIONS/BENCHMARKS
4.1
A technical committee constituted by the Ministry has shortlisted equipment
essential for operating a CRS. This list has been made in such a way that it will
generate a multi-vender response. The committee has also finalized
specifications/benchmarks of each item on the short list. This will be the benchmark for
equipment to be purchased by CRS under this scheme.
Funding will be provided only for equipment as per specifications laid down by the
Ministry. List of equipment shortlisted and specification/benchmarks thereof are at
Annexure. The Technical Committee would review the list of equipment at periodical
intervals.

5.
GRANT SIZE:
5.1
A basic set up of community radio station may cost around Rs.15 Lakhs. The
maximum grant size in the current FYP will be 50% of the total estimated expenditure,
subject to a ceiling of Rs. 7.50 lakhs. The remaining amount will have to be contributed
by the grantee, for which the grantee will submit supporting documents.
6.
NUMBER OF BENEFICIAIRES:
The Scheme will support 100 new CRS and 30 existing operational community radio
stations each year. Under the scheme, a total of at least 650 grants are likely to be
made over the 12th Plan Period (2012-2017).
7.
ELIGIBILITY CRITERIA:
7.1
Assistance to Community Radio Stations will be provided by the Ministry to
following:

obsolete and unserviceable or condemned in accordance with provisions laid
down in GFR. After a period of 5 years from date of purchase of equipment,
CRSS grantee may request MIB to dispose of/transfer of equipment. Such
transfer/dispose of will be through an explicit letter issued by MIB thereof. While
disposing of or transferring of equipment, the depreciation as per GFR
provisions will be accounted for. The pro-rata value of depreciated value of
equipment, in the ratio of grant provided, will be recovered from grantee and will
be ploughed back into the scheme.
ii) Applicants must conform to pre-agreed timelines, both in terms of application
and utilization of the grant and ensure that utilization of grants are
commensurate and conform to their purpose. Also applicant will maintain
transparent and auditable financial records of the grant and its utilization

Mast or Transmission Tower
Mast (tower) is used to mount antenna at a desired height. For community radio maximum
height of antenna should not exceed 30 meter from ground level. Any one of the following
types of Masts/Towers may be procured. The offer must include Supply and Erection of Tower,
including construction of foundations, mounting of antenna, R.F. Cable and Cable Tray.
i) Guyed Mast: A guyed mast is a tall thin vertical structure that receives support from
guy lines. It is cheapest, but requires lot of space.
ii) Self-Supporting Mast: Self-supporting Towers are ideal for installations where space
requirements are limited. It is costlier than guyed mast.
iii) Concrete Tower: Reinforced concrete towers are relatively expensive to build but
provide a high degree of mechanical rigidity in strong winds.

C. Concrete Tower:
DETAILS OF THE MONOPOLE
The 30 m high pre-stressed spun concrete monopole, self-supporting with mountings at
different heights. The entire height of the monopole is to be divided into minimum 3
panels/segments. As requirement is from 15Mtr to 30 Mtr, hence outer diameter of tower will
vary. However, for 30 Mtr tower outer diameter of Bottom must be 600 mm with tapering to
190 mm at the top. The cross-section should be annular with thickness varying along height
capable of the following:
i) Height:
Maximum 30 Meter & Minimum 15 meter (From Ground)
ii) Wind load:
47 kg/cm2
iii) Wind Velocity:
170 km/hour
iv) Able to bear a load of 25 kg in addition to cable, cable tray & ladder
v) The design should be approved/vetted by a recognised Engineering College/Institute
ANALYSIS AND DESIGN
The monopole should be analysed for the various load combinations. The monopole should be
modeled as a beam element. The wind load on the pole should be calculated by using the Gust
factor method as per Clause 8 of IS 875 – Part 3.
The wind loads due to antennae and the panels should be calculated and applied in the analysis.
Dynamic analysis should be done and analysis results to be presented.
As per IS 456 – 2000, the following load combinations should be considered in the analysis:
(i) 1.0 Dead load (DL) + 1.0 Wind Load (WL)
(ii) 1.5 Dead Load + 1.5 Wind Load
(iii)0.9 Dead Load + 1.0 Wind Load
The design of the pre-stressed monopole is to be done as per the limit state method. The limit
