                                     1. After our conversation oni3.s subject on 30 December,
                              the question was discussed with Mr, I  ,III  TSD/AOB,   and
                              Mr.4    7  -   TSD/QRF. The following  information it forwarded
                              for y or consi eration as a result of our discussions.
                                                                                        7 '
                                     2. Mr          Audio Operations Branchr-recommends  two
                              companiesas  sources o equipment of this nature. These companies
                              have experience, under classified contracts with TSD, in producing
                              reliable equipment for special purposes of this sort. They also,
                              of course turn out commercial equipment of good quality for normal
                              communications needs.  These com anies are:

                                          a.  otorola, Chicago, Illinois
                                          b  Kell Cambridge,  Massachusetta  Aq'0B

                              The TSD VHF  radio switbh eqpm  at for demolition needs was
                              developed for us by(Motorola.    j      ransistorised sets have
                              been produced to me t the special needs (rt& for demolition purposes)
                              of other SAS projects.

                                    3.  In the opinion of both persons consulted, the expenses noted
                              in our first discussion should have produced a reasonable amount of
                              workable equipment if the source was both capable and reliable,
                              3SD recommendd' the use of frequencies in the VHF/IUF spectrum for
                              equipment of this sort and crystal tuning control for reasons of reliatIty,
                              selectivity and rejection of spurious signals.

                                    4. Inexpensive equipment of Japanese or.American manufacture
                             In the citisens band frequency ranges for toys, ra4io control devicea, .
