When toggling between MAIN- and SUB-RX the actual settings of the controls
used at last are not transferred to the new active RX – instead the former
settings of this RX are the actual one – until they are overwritten by the
respective control.
The squelch threshold set to the RX working
in the background will stay the
actual one when this RX becomes the active – until one touches the squelch
control to set the threshold to a new setting.
The large S-meter is always allocated to the
active RX. The smaller S-meter is
indicating the field strength of the RX working in the background .
Transmitting (TX) is only possible when MAIN-RX is the
active one and SUB-RX
is working in the background .
When transmitting the SUB-RX may be used to monitor own RF-signal.
Receiving with SUB-RX on a separate antenna is limited however: Excessive
field strength may trip the protection circuits. Receiving at frequencies adjacent
to the transmitting frequency may be limited even by the superior dynamic
characteristics of the PT-8000A receivers - which are of course finite.
