Hi Glenn,

For radios that support "split" (most Baofeng dual-band radios do),
what you do is set Duplex to "split" and then set Offset to the
absolute TX frequency. See the Offset field of the Understanding
CHIRP's Columns guide in the CHIRP documentation area.

Here is how it should look in the spreadsheet style Memory Editor.

Frequency: 437.800000
Tone Mode: Tone
Tone: 67.0
Duplex: split
Offset: 145.990000
