These working units were  removed from my aircraft in 8/17 when I did an avionics upgrade.  The tray is 6.3"W x 2.6" H x 11.4" L.  The units weigh 4 3/4 lb.  The TX760D has a frequency range of 118.00 to 136.975 Mhz, 5 watt output, active and standby flip/flop selection, 10 channel memory, and built in intercom.  The TRT250D is completely solid state.  Altitude encoder is NOT included. 

Purchaser must determine if this equipment is airworthy and suitable for its intended purpose.
