DES MOINES (AP) — Nearly two years after questions first arose about the way Iowa asked for bids on law enforcement radios, some vendors are still complaining.

At the heart of the dispute is the question of whether the state is trying to set up the bidding process to favor Motorola radio and make it impossible for other radios to be chosen, as some vendors believe.

The Des Moines Register reported the contract would be worth about $7.5 million because Iowa wants to purchase radio equipment for the State Patrol and the Departments of Natural Resources and Corrections.
