ok so earlier tonight I removed the Trackmate USB interface and soldered two wires to the bottom of the interface and attached the other two wires into the topside of the interface with the already attached wired track call button, as per the simple instructions and tested the wireless button out.

omg... the range on this thing is phenomenal and it all works very nice. This will make marshalling the large track so much easier. Highly recommend the wireless Trackmate track call button.
