Cross Band Repeat:
1.Cut R122

Notes:
The microphone is LIVE in this feature! You can disconnect the microphone. However, the audio is low. What I do is lay the microphone over the speaker. NEVER crossband 2 repeaters!!!

Enabling Crossband repeat:
1.Press the "F" (Orange function) key
2.Press the "A.B.C." key within 5 seconds from step 1.
The dots will light in the decimal location on the MAIN band.

Disable the 3 minute timer for transmit:
1.Remove R122

Out-of-Banding:

Notes:
This radio already recieves from 138-170MHz on VHF and 438-449.995MHz on UHF. The radio can transmit out of band. I will not post that mod because I feel most Hams don't need it. This one of Kenwood's first dual band radios. Moding it for out of band operation degrades the performace in the Amatuer Bands. This was a problem with early broadband radios.
