  • 1.The project will create a standard model for technical requirements of the FM transmitter full solid –state acquisition(technical features + factory/site acceptance tests) 2.Based on that a study of the transmitter manufactures market will be issued. 3.Prepare the documentation and organize an international tender fallow of the offers analyze and selection of the winner. 4.The Draft Contract for the FM transmitter acquisition will be issued.
  • 1.Experimental broadcasting –means that the transmitter is running on the usual daily program but any broadcasting gaps due to the equipment shall be permitted. 2.After the end of the experimental period a final report will be issued and will contain the major faults of the equipment and the conclusions of the reliability of the equipment operation.
  • 1.The band 85.7-108Mhz began to be occupied by the commercial networks and the risk for the public radio is to run out the frequencies in FM.
  • 2.The national coverage implies a huge cost of the network and more time frame to be finished.
  • 1.New full solid-state technology will be used- comparison with tubes technology: Ultra-low harmonic distortion (0.0016%), FM signal-to-noise ratio(-90dB), peak limiter using “lookahead” techniques with no affect on pilot carrier. 2.Using a digital modulator; Immune to subsonic program line transients; no AFC trips and no AFC relock tome due to subsonic noise bursts(no modulated VCO). 3.At the last : Costs, but not the lasts; Power supply consumption and air filters (regular maintenance also).

    • 5. Competitive Analysis
      • Competitors
        • Commercial private radio networks (i.e. PRO-TV, CONTACT, RADIO ROMANTIC, etc.)
        • Private local radio stations.
      • Strengths
        • Infrastructure: buildings, masts, power service.
        • License for 2 national FM networks (37 transmitters, each).
        • Commissioning the equipment by own people.
    • 6. Competitive Analysis, Cont.
      • Weaknesses
        • The state budget allocations.
        • The FM networks ought to have a national coverage.
        • The old FM networks operate in band OIRT (64MHz – 70.4MHz).
