NOTE ‘Pittsburgh ascertained that a cottage is under construction in a remote suburban area approximately 25 miles northeast of Pittsburgh, Pa., and 8 miles from New Kensington, Pa. An informant has advised that this cottage, when completed, will be utilized by Gabriel Mannarino, Pittsburgh top hoodlum. He has also advised hoodlums from the Pittsburgh area and from other parts of the country will probably utilize this cottage as a meeting place. Pittsburgh recommended that the premises be surveyed to determine if special covérage could be installed. Pursuant to Bureau authority, this survey was completed - and Pittsburgh recommended installation of a radio-microphone type of equipment.

In addition, such an installation would not be productive until telephone service was requested abgs Ingbalied at the cottage. Regarding, suggestion No. 2 (use of an undergroung cable): The, distdnce, terrain and security problems involved would make such an undertaking extremely difficult.

Based on current knowledge, a Putin tallation(S) is believed feasible. The possibility of running an underground cable has not been entirely abandoned but additional surveys would be necessary to make a full evaluation.

The various aspects of providing MISUR coverage under the peculiar conditions presented ‘by this case have been considered. The presentation of the survey material submitted is excellent reflecting thoroughness in the survey and detail - in the proposed installation. 7 From the installation standpoint, the radio-microphone installation recommended may be feasible; however, other technical factors rule out the use of radio-microphone equipment in proposed installation. This type — equipment ig suitable only for short term installations where operation for a few days or a week or two may be expected to provide the desired coverage. Radio-microphone equipment is not désigned for continuous operation over longer periods of time and it must be expected that extended periods of operation will result in failure of transmitter tubes or other components. Control equipment suggested to provide intermittent operation of transmitter would not eliminate this problem since control equipment would be in continuous operation and therefore would be subject to failure. It appears that two possibilities exist whereby MISUR coverage of this residence may be effected by operation of microphone over wires.

Should telephone seryjce be requested it may be possible to operate _alSingle Pair Microphone- (S Telephone (SPMT)._JThe|SPMT junit may also be used to operate one or two microphones or MOUSE units on the subscriber's telephone wire without _ additional wires. Microphones could be installed prior to occupancy of the cottage andleads connected to telephone lines when tglephone service is established: Operation of Spartii requires (s} that the subscriber's line be f0ope through the monitoring point which must be located somewhere between the subscriber's telephone instrument and the telephone company central office. Section 26, Part.1,; Handbook of Technical Equipment sets forth details of this equipment and technical considerations necessary fo] SPM Tpperation. 6) 2. The possibility of using underground wires for microphone egress is a possibility in this case. It may be possible to follow the route of the water or sewer lines in the immediate vicinity of the cottage andthen route the underground cable to telephone company pole where connections can be made to telephone wires leading to a plant. Security of wire laying operations and terrain conditions will largely determine whether underground wire can be laid to a: suitable point for. connection to overhead telephone wires. : It is desired that any additional survey necessary be conducted to | evaluate these possibilities for MISUR coverage, and that the Bureau be advised without delay whether either approach in this MISUR installation appears to be feasible. a Loo DoclIda: 32303050 Page 10

All known ways and means of establishing such a misur have \ “ been carefully considered.

This choice was made in view of the following factors relating to technical problems, security considerations. 7 4 and investigative advantages: ash (1) It is recognized that the use of telephone wiring disguises are generally considered more secure than the use of radio-microphone techniques.

VY Ve La a PG 92-236-Sub 2 There is a 34 foot deep crawl space under most of the cottage. The floor is of 3/4 inch plyboard and is 7 - eovered with heavy carpeting, The cottage has no attic space since the roof and interior ceiling run parallel to one another at all points and are separated only by a 4" insulated . space. The interior walls are of mahogany panelling. Approximately 14 inches from the wall-ceiling junction, a 4 inch wide white painted decorative molding extends around certain of the interior walls (noted on Peete 5).. Separate pieces of panelling (about 14 inches by 36 inches) have been used above the molding and it appears that these can be removed without disturbing the molding or the lower portions of the panels. Around certain of the walls in the dining- kitchen area, at the same height as the molding, a 14 inch by 20 inch hollow..boxing has been constructed to provide concealment for heating ducts, plumbing and electrical a wiring (noted on Figures 3 and 5). ; PROPOSED INSTALLATION It is proposed that three microphones and two transmitters be installed in the manner and location illustrated in Figure 5. First choice is indicated in red-- second choice in green. The small panels above the molding can be removed with relative ease and microphones No. 1 and No,'2 installed behind as illustrated in Figure 4. Microphone No. 3 can be imbedded in the upper surface of a ledge extending across the north side of the porch. The lead wire for microphones No. 1 and No. 2 can be securely hidden behind . the molding and will be completely hidden from view even’ on close inspection. The lead wire for microphone No, 3 will be in parallel. with microphonesN6. 2. Certain portions of the lead wires will extend through the hollow boxing. The top of this boxing is about 73 ft. above the floor and the interior is accessible only from the top. The top is covered with 1 inch by 12 inch boards. As illustrated, certain portions of this boxing will be used to carry the lead wires. All lead wires extending through this boxing will be disguised as Romex cable even though the chances of any subject in- specting this boxing is very slight.
Released under the John F. DATE: Pa) a 5 ON “ - er PG. 92-236-Sub 2 Position No. 4 is the proposed location of the transmitters. This position is within a portion of the boxing on the east side of the kitchen, 117 v. ac. is readily available within this .boxing. It is anticipated that the transmitters can be mounted in a wood or metal box and marked "automatic pressure regulating device for water system." (The cottage is provided with its own water system. The pump and compressor are located under-one of the kitchen cabinets in’ the northeast corner of the kitchen.) The antennae can be disguised as pieces of Romex cable. After this equipment is installed, it is planned that the 1 inch by 12 inch cover boards will be nailed in place, In the alternate location (green on Figure 5) the transmitters . would be located in a space above the low ceiling of the shower stall. Access to this space would be gdined by removing the small panels mentioned previously. Alternate microphone No. 2 would be located in the base of a light fixture mounted on the boxing. Two transmitters are proposed in order that coverage will ' continue if one should fail and in order that selective coverage may be had within the cottage. Investigation and observation reflect: that it is practical and secure to mount the receiving equipment on a telephone pole in the near vicinity of the cottage. Atelephone line and 117 v. ac. can be terminated on the pole. The telephone line would, of course, terminate in either a local plant or the Pittsburgh consolidated plant. The equipment can be mounted in the weathexproof box which can be locked. The box would be marked "ESerimental telephone carrier system equipment." The receiving antennae can extend along the. pole and can be disguised as:ground wires. It should be possible for the personnel at the monitoring position to Select the output of either transmitter. Figure 6 illustrates two telephone poles in the vicinity of the cottage where both power and a telephone line can be terminated. The distances of these poles from the cottage are indicated. | Docld:32303050 Page 153 Kennedy Assassination Records Collection Act of 1997 (44 USC 2107 Hote}. 11-14-2017 i ; , aw . . . oo yf

If this proposed installation is approved, it is respectfully requested that the Laboratory assemble the necessary trans- mitting and receiving-remote control equipment in accordance with the following specifications: The transmitters should be as small, as stable and as trouble- free as posSible. Selection of the transmitter frequencies will be left to the Laboratory. The output power should, of course, be well below the minimum power requiring a license and should be no more than necessary to provide “solid” reception at the receiving site (600 yard range). Care should, of course, be taken to prevent any harmonic radiations in amateur broadcast or television bands. The power consumption and the heat generated by the @quipment should be as low as _possible., It is anticipated that Knowles 50 ohm microphones “s will be used. As was previously stated, it is anticipated that microphones 2 and 3 will be in parallel. The equip- ment should be mounted in a suitable wood or metal box with Romex fittings attached for power input, audio input and antennae output. The size or the power consumption of the receiving equipment } is not critical. This equipment will be available for servicing. Through the use of direct current impulses originating at the monitoring end of the telephone line it should be possible to energize a relay at the receiving point which would select the output of either transmitter. It should be possible to control the audio output level of the receiving equipment. This equipment should be mounted in a suitable waterproof box with a lock. Pittsburgh presently possesses one Knowles 50 ohm micro- phone. Two additional microphones are needed. All other supplies will be obtained locally. | ‘Much of the microphone lead wire will run parallel to a.c. house wiring. The Laboratory's opinion regarding the advisability of using shielded lead wire is requested. =5- DoclIda: 32303050 Page i4 ae a

Prior to any entrance into the cottage, all logical. subjects who might enter the cottage will be placed under surveillance and will be surveilled during the entire operation, Special Agent personnel who are well acquainted with all logical subjects will be placed at either end of the road and will provide additional warning of any possible approach of the subjects. .It is, of course, realized that trespass - Will occur but everyprecaution will be taken to prevent any possibility of compromise. COSTS The telephone company source will place 117 v. AeCe on. the selected telephone pole for a maximum charge of $20.00. There is a $2.00 per month minimum charge for power used. A leased line from Leechburg to Pittsburgh will cost a maximum of $85.00 per month. It is believed that superior overall results would be obtained if the receiving equipment could be monitored in the vicinity of Leechburg. It is realized that the - cost of maintaining a plant and monitoring personnel at ' a Leechburg would greatly exceed the cost of monitoring » the installation at the Pittsburgh consolidated plant, however. The details of the cost of monitoring at the consolidated plant will be included in the first justification letter if this installation is approved. It is recognized that there may be no pertinent activity at the cottage for some time. In order to save the cost od of leasing a line to Pittsburgh, it is suggested that the source not, be monitored until it has been estimated through PG-545-c that frequent activity is taking place.
