Does the Kenwood TH 7AG do Full Duplex?

Yes!

 

Using the TH-D7 with amateur radio satellites for voice communicationEdit
  1. See the HAM Satellites page for general amateur satellite techniques.
  2. Use the Duplex feature to receive audio on one band while transmitting on another. Press the “DUP” key and observe that the “DUP” indicator is lit on the display. NOTE: You'll need an earphone with a 2.5mm plug or a converter to avoid audio feedback.
  3. The TH-D7 is incapable of memory frequency splits across bands. If tracking doppler shift on the uplink is required, then a second set of memories is necessary along with manually swapping between bands to adjust the frequency as the satellite arcs overhead. 2 meter doppler shift may not be significant enough to warrant the effort on the uplink.

Thanks.
