Now, Maoists using HF waves to escape surveillance
Naxal cadres have now begun to communicate through High Frequency (HF) radio waves which the security forces are finding hard to "tap".
Raipur: In order to avoid being intercepted
by police and intelligence agencies, armed naxal cadres have
now begun to communicate through High Frequency (HF) radio
waves which the security forces are finding hard to "tap".
Top security officials deployed to undertake anti-naxal
operations in Chhattisgarh and other states say an increasing
number of Maoist cadres have now begun using the HF radio
waves instead of Very High Frequency (VHF) waves used earlier,
to escape the surveillance radars of intelligence units.
The forces are now looking to obtain and deploy advanced
interception equipment which can intrude the HF waves.
"Naxalites and their cadres have been using cellular
phones and VHF sets to communicate but recently we have found
that they are now communicating on HF sets," Deputy Inspector
General (DIG), Border Security Force (BSF) Ram Avtar said.
We have been using our in-built equipments to track and
intercept Maoist communication on wireless for quite sometime
now, said the BSF officer, who commands five battalions (5,000
personnel) of the force in Kanker.
The BSF DIG, however, refused to divulge more information
saying new methods are being developed and deployed to gather
intelligence in this regard.
"Intercepting and tapping Maoist communication is a very
vital intelligence for police and security forces. Movement of
armed naxal cadres and their activities have been intercepted
a number of times, giving the forces` a crucial edge in
operations," a senior police officer, who requested anonymity,
The forces deployed in the anti-naxal operations grid
like CRPF, BSF and state police have been using vehicle-
mounted devices called `DF vehicles` which intercept radio
communication. "But so far we do not have any equipment which
can intercept HF 100 per cent," the officer said.
Some equipments developed by the Defence Research and
Development Organisation (DRDO), used by security forces in
Jammu and Kashmir, are already in place. Some new equipments
are now needed to intercept the HF waves, he added.
A senior officer looking after anti-naxal operations here
said senior cadres of the Maoist hierarchy use HF frequency
for radio communication while it has also been found that they
use multiple SIM cards to communicate with their cadres.
"The new challenge is to intercept the HF radio and
wireless which will give the security forces two types of
intelligence and information. One about the naxals operations
and the other about their activities against the security and
police forces," a senior CRPF officer said.
