PROGRAMMING Introduction When you order a Derringer audio transmitter, DTC will factory program your frequencies at no additional charge to you. You may want to place a sticker over the rotary switch on the chassis so users in the field don’t attempt to change frequencies. This is often the best path for state and local agencies with limited frequencies available to them. DTC will also provide you with free software and a free programming cable, enabling you to change your transmit frequencies.
