Examination requested by: SAC, Columbia
Reference: Airtel dated 1/11/79
Examination requested: Duplication
FBI file no: 89-4286
Lab. No.: 90116002 E SH

Remarks: For information of Columbia, due to the large volume of tape recordings received in this matter, no enhancement examinations are being conducted except in exceptional circumstances. Additionally, the interference and distortion present on the radio transmissions are not generally amenable to enhancement.

One copy of Q831 has been submitted to the Technical Evaluation Unit of the FBI Laboratory for such examination as they deem appropriate.
