4.1 SO2R (Single Operator Two Radio)
This kind of operation is used during a contest in order to acquire, as more 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 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) 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 RTX2 to the 40 m antenna, while RTX1
will be switched to the multiband antenna in order to receive the 20 m band.
Note: the isolation between the transmitting antennas and the receiving antenna must be very
high and, therefore, very well planned. Locating the antennas at some distance from
each other, and using appropriate band-pass filters will help to achieve this.
SPE cannot be responsible for any damage caused to equipment by using this mode of
operating.
