A remote-control device seized from the family home ofMomin Khawaja was in working order and was capable of being used totrigger a homemade bomb, says an RCMP expert on electronics andexplosives.
Sgt. Sylvain Fiset told Khawaja's terrorism trial Wednesday thatthe device - dubbed the Hi-Fi Digimonster - would have had a rangeof up to 300 metres as originally conceived.
But his analysis indicated that the maker later modified the designto include a new antenna, likely with the hope of increasing therange.
"In fact, the tests (carried out by the RCMP) showed it had thereverse effect, the range was decreased," said Fiset.
When outfitted with the new antenna, the Digimonster had a range of200 metres in an open field and of no more than 100 metres indensely built and heavily populated areas.
The device included an amplifier that, in theory, could haveboosted its range to one or two kilometres, said Fiset, but it wasimproperly installed and wasn't getting the job done.
Nevertheless, he concluded, the Digimonster would have functionedadequately within its reduced range.
In a follow-up discussion of homemade bombs - known in technicaljargon as improvised explosive devices - Fiset noted they can betriggered in any number of ways.
A mechanical timer or trip-wire would be two crude examples, hesaid. More sophisticated equipment that could be used to send anelectrical signal to set off an IED would include a pager or cellphone, or "it could be a device like the Hi-Fi Digimonster," saidFiset.
He said he built and tested two duplicates of the Digimonster basedon diagrams, photographs and electronic components discovered bythe Mounties when they raided the Khawaja house in March 2004.
Fiset explained that he didn't want to take a chance of testing theactual device that was seized in the raid, for fear it would bedamaged if something went wrong.
He estimated the duplicates he constructed were "95 to 99 per cent"identical to the original. But a written report entered in evidenceWednesday indicated Fiset may have taken some liberties.
He noted in the report that some of the original materials were of"meagre" quality and some of the soldering jobs were "fragile" innature. He used better materials and soldering in building theduplicates.
Khawaja faces seven charges including financing and facilitatingterrorism, but the central allegation is that he built aremote-controller for use in bomb attacks planned by Islamicextremists in Britain.
