      *   The dwell time at any particular frequency during testing is less than 10 seconds
      *   The power levels being transmitted during testing are low (.5 kW ERP max)
      *   The transmitting antenna will be in close proximity to ground level, which will
          grea: y . mit the range of the transmitted signal, and will be located in the center
          of Carerpillar property
      e   The sransmitted signal will have a very narrow bandwidth (2 kHz max}, which in
          itsel! reduces potential interference to television stations
      *   We propose to make these narrowband transmissions 2 kHz above the bottom of
          the channel edge, so as to further minimize interference potential to analog and
          digital TV stations
      #   Prefiminary interference studies have shown that the probability of interference
          to the stations in question will be extremely low (see attached technical
          doc.mentation)

Detailed technical information about our proposed operation, along with preliminary
interference analysis, is attached.

If this request seems reasonable, we respectfully request that you sign at the bottom of
this docu—rent where indicated and return a copy to the undersigned via facsimile and
mail.

Thank you ‘or your consideration. Please contact me if you have any questions about
Caterpillar‘s proposed RF immunitytesting.



Sincerely,
