To US users: As of October 13, 2018, the manufacture, import, sale, lease, offer for sale or lease, or shipment of wireless microphones or similar devices intended for use in the United States that operate on the 600 MHz service band frequencies (617-652 MHz and 663-698 MHz) is prohibited. Further more, all usage of these units is prohibited in the US after July 13, 2020. Due to this rule, if you have one of these units and want to sell it, please explicitly specify in your post that you cannot sell to a buyer in the United States. Alternatively, you may list these items (and these items only) in the Europe & International Classifieds (but not both).
