4.1 SO2R (Single Operator Two Radio )
This kind of operation is used during a contest in order to acquire, as quickly as
possible, a new multiplier.
The following connections are needed (see the diagram):
1.
INPUT 1
connected to the first transceiver (RTX1).
2.
INPUT 2
connected to the second transceiver (RTX2).
3.
ANT 1/2/3/4/5/6
connected to the available antennas set.
4.
SO2R
connected to a multi-band antenna.
The operating mode could be the following:
If you are operating using RTX1 on a given band (e.g. 20 m), the correct antenna
(ANT 1/2/3/4/5/6 is automatically selected while RTX2 is connected to the multi-band
antenna in RX mode on another band.
If, when operating on 20 m, a multiplier of interest is heard on RTX2 (e.g. 40 m), the
only action needed is to push the PTT2 in order to connect RTX2 to the 40 m antenna,
while RTX1 will be switched to the multiband antenna in order to receive the 20 m band.
In place of the multiband antenna one of the antennas ANT 1/2/3/4/5/6 can be used, in
such a case all of them must be mono band to avoid the danger
of using the same
antenna for RTX1 and RTX2..
A careful design is needed to avoid such a danger which could be devastating for the
receivers.
This possibility is available with the optional external unit "SPE SO2R1" according to the
following
diagram.
