Kenwood THD-72A/E Duplex function
At the (British) National Hamfest yesterday I had a play with the pre-production model of the THD-72E and asked about full duplex.
I couldn't get into full duplex on the menu and had to give the set back but I insisted onthe question in the name of AMSAT and they went to the manuals while some other guys played with it.
On the second manual(printed off the cdrom) - which they said was about the packet function - there was the following instruction:
"FULL DUPLEX Ths transceiver is also capable of simultaneously transmitting and receiving signals. So it is possible to transmit audio on the current band while receiving packet data on the other band (data band).
1 Set operation band to band B 2.Press [F DUP] to enter Duplex mode ...
Notes * When operating on band A you cannot change to full duplex mode. * When in single band mode and Band A/B is set to VHF/VHF or UHF/UHF you cannot change to Full Duplex mode. * When usin the Full Duplex function, connect an earphone to the SP jack. using an earphone will prevent feedback that can cause the transceiver to emit a howling sound."
I have photographed these instructions and transcribed from the photo. For some reason I photographed the manual not the radio which is a squat fat two-tone grey thing. It's got a gps built in. Available end 2010, they said.
