If you have a 6 kHz filter installed,
you can use WIDTH to select a wider passband.
In CONFIG:TX eSSB, change the parameter
from OFF to one of the provided selections
(3.5, 4.0, etc.).
With eSSB enabled, the transmit EQ menu entry name changes to MAIN:TX*EQ to allow you to independently adjust EQ at the selected wider bandwidth. The amount of adjustment required at each EQ band may vary depending on the selected eSSB
transmit bandwidth. (See manual pg 36) |
