11.7 SPLIT Operation
SPLIT Operation using VFO SPLIT function
SPLIT Operation using MAIN-RX and SUB-RX
SPLIT Operation using RIT/XIT
There are various ways to split between transmit- and receive frequencies.
Keep in mind that the PT-8000 represents a transmitter with two identical
receivers. However, to link a receiver with the transmitter as a transceiver is
only possible with the MAIN-RX. Hence only the MAIN-RX VFOs can
determine the transmit frequency.
Three ways for SPLIT operation are available:
•
•
•
Tune with VFO A to the station you would like to call. Select VFO B and tune
to the desired transmit frequency. Make sure the same mode is selected.
Reselect VFO A. Press SPLIT. Now VFO A is for receive and VFO B is for
transmit.
Of course you can tune with VFO B to receive and tune VFO A to the
(split)transmit frequency. Selecting SPLIT will always chose the alternate VFO
for transmit. Pressing VFO A/B will alternate RX and TX frequencies.
Pressing SPLIT again will terminate SPLIT operation.
The actual operating frequency in RX/TX will always be displayed as the
selected VFO frequency; i.e. during SPLIT the display will change with T/R
switching.
Tune with SUB-RX (either VFO) to the station you would like to call. Tune with
MAIN-RX to the desired transmit frequency. You can monitor the stations
calling and the station to be called simultaneously. This might give
advantages in crowded environments. Use the volume control for MAIN and
SUB to adjust convenient monitoring.
Tune with MAIN-RX to the frequency of the station you want to call. Engage
XIT and select an offset that you desire to call the station.
