AID - Westinghouse/Audio Intelligence Devices, Inc. Bug Frequency 135 MHz - 150 MHz Special Order/Secondary Band (also 138-162 MHz) 150 MHz - 174 MHz Standard/Primary Band (Most Popular Band) 216 MHz - 220 MHz Special Order 400 MHz - 470 MHz UHF Repeaters 806 MHz - 821 MHz Digital Spread Spectrum TX-8xx (BPSK-407kb Direct Sequence) 851 MHz - 869 MHz Body Pack/Wire (NFM) TX-11xx 902 MHz - 928 MHz Digital Spread Spectrum TX-8xx (BPSK-407kb Direct Sequence) 21 MHz - 80 MHz Very Low Power WFM (.5mw - 10mw) Special Order Only 36 MHz - 39 MHz Very Low Power WFM (.5mw - 50mw) ***Very Dangerous*** 80 kHz - 200 kHz "Line Carrier" Microphone Systems ***Very Dangerous*** 30 kHz - 700 kHz Spread Spectrum Current Carrier Devices 1700 MHz - 1900 MHz 25-250mw Video and audio bugs (Mostly Federal Video Bugs) 2400 MHz - 2484 MHz 25-250mw Video and audio bugs (2.450 to 2.483 very popular) If the signal is "scrambled" it is nothing more than simple voice inversion, a circuit to "de-scramble" can be built for around $15. Note: AID devices are often re-tuned for out band channels... so be careful. The area of spectrum from 15 MHz to 500 MHz is the primary threat, 500 MHz to 2.7 GHz is the secondary threat, a "line carrier" threat is from 30 kHz to 750 kHz. If the person planting the bug suspects that a TSCM inspection may be conducted then AID suggests a frequency between 30 MHz to 50 MHz, sensitivity of receiver should be better than .18uv/-122dbm. The mode/modulation is recommended by AID to be wideband FM. Also, keep in mind that AID devices are frequently used for illegal buggings, so be familiar with what their realistic specs are, expect power outputs well under 50mw, and expect to see the AC power circuits being used as the antenna.

WARNING:
The area between 600 MHz and 9 GHz is EXTREMELY DANGEROUS as the
eavesdropping equipment in that range is inexpensive, very low power,
and highly directional.
Additionally, most TSCM people tend not to check frequencies above 1 GHz or 3 GHz (because the equipment is an order of magnitude too expensive for them to buy).
