This is the same transmitter as the 916 MHz version except that it operates on the 868 MHz “euro” ISM band and pairs with the 869 MHz receiver. Will not work or interfere with the 916 MHz receiver.
Takes the DCC signal from your existing command station and puts it on the air to be picked up by the receiver(s) in your locomotive(s) (see above). Simply connect to the back of your command station to the rail outputs and place in the center of the room near the ceiling. Use twisted pair or speaker cable for long runs (> 10 ft) back to the command station. Since the transmitter only draws 21 mA, the wire can be as small as 28 ga. Only one transmitter is needed for the entire layout. This device transmits low power radio frequencies on the Instrument-Scientific-Medical (ISM) band (also used by 900 MHz cordless phones) with a range of about 50 feet.
The new MKII version is smaller and more compact. Dimensions are 79mm (3.125″) 20mm (0.812″) long by 15mm (0.635″) thick. Input: DCC 5-30V peak-peak; uses 21 mA (.02A). Ouptut -4.3 dBm 869 MHz..
This unit complies with FCC Rules Part 15 for Class B devices using the included antenna.
Will interfere with another device that operates within ~0.5 MHz of this device. So if you have another radio device in your train room check that it is on a different frequency.
COVID-19 INFO: Arizona has issued an ordinance for us to shelter in place through the end of April. Orders will be accepted and processed, hopefully, with no change in service. Thank you for your patience! Dismiss
