RF analysis has changed
For a while bugging transmitters were getting more elaborate and trickier to find using RF analysis you were finding devices becoming commercially available that could be programmed to be switched off by remote control if the attacker knew that a bug sweep team were in the building, the device would send its data out over a frequency hopping or spread spectrum signal they could be even sent over a signal that was both spread spectrum and frequency hopping and all encrypted so no one can accidentally tune into the signal.
These signals were proving difficult find with older equipment but with the release of the Winkleman raptor and the REI Oscors these devices were once again easily found by proficient TSCM operators.
Now with the release of SDR radio receivers by signal hound and Thinkrf and amazing software by Radioinspector and Kestrel a proficient electronic bug sweep team know no boundaries.
