First is a pair of TQ 27MHz transmitters and receivers.
The one on the left with the smaller receiver works perfectly.
The one on the right is missing the transmitter battery door,and the receiver has a damaged antenna which reduces the range to about 50 feet.

I'll sell both for $35 shipped (con. US shipping only)

Second is a TQ 2.4GHz transmitter (model 6516).

$20 plus shipping (con. US shipping only)

Or...I'll take $55 shipped for all 3.
