Overriding the Duplex Offset
When you tune to a frequency, the HTX-212 automatically selects either
simplex operation, or duplex operation with the correct offset direction. To
override this setting, press SHIFT. Each time you press SHIFT, the offset
switches between +, –, and no offset. The setting returns to the default if
you change frequencies or turn off the HTX-212.
Note: The HTX-212 will not switch to an offset that would place the trans-
mit frequency out of the permitted transmit range. For example, you can-
not set the offset to – for frequencies less than 145.200 (600 kHz above
the minimum transmit frequency of 144.600).
USING THE DUAL VFOS FOR DUPLEX OPERATION
Follow these steps to use one VFO to transmit and the other to receive.
1. Press VFO to select VFO-A.
2. Select a frequency.
3. Press VFO to select VFO-B.
4. Select a frequency.
5. Press DUP. When the HTX-212 displays:
VFO-A-T
VFO-B
it transmits on the VFO-A frequency and receives on the VFO-B
frequency. When it displays:
VFO-A
VFO-B-T
it transmits on the VFO-B frequency and receives on the VFO-A
frequency.
