Advanced Installation with DPDT Relay for Stryker SR-955 HPC
Refer to FIG. 1
1-
Remove jumpers J3 and J4. NOTE: for regular stock AM use, including SSB and FM, these
jumpers must be in their original factory location and the Asymod III fully disconnected. To use
the Asymod III and maintain SSB and FM functionality this or the DPDT Switch advanced
installation bellow must be performed beginning on page 8.
Refer to FIG. 4
2-
Run a wire from the Asymod III, HI-OUT+ terminal (
3
) to RL1 pin A2 as shown.
3-
Run a wire from the Asymod III, HI-OUT- terminal (
4
) to point
C
or
D
(Chassis Ground).
4-
Run a wire from the anode of D515 (FIG. 2) to the Asymod III +12V input (
1
) terminal and
connect the – input (2) terminal to point
C
or
D
(Chassis Ground) as shown.
5-
Run a wire from L32, point
E
(+12v) to RL1 pin B2 as shown.
6-
Run the rest of the wires from RL1 to J3 and J4 as shown.
7-
Connect one side of a SPST mini switch to L32, point
E
(+12v) and connect the other side to RL1,
pin
F
(coil), connect RL1, pin
G
to
point
C
or
D
(Chassis Ground). Add D1, a 1 Amp, general
purpose diode as shown.
8-
Please refer to FIG. 3 for audio input connections. Connect the audio output from your
microphone or audio processing chain to the Line In terminals
5
and 6. You can run the audio in
through the rear of the transceiver using a ¼” female phono chassis mount jack, or if you prefer
to use the transceiver’s hand mic, other microphone or line out from you audio process chain
connected directly to the mic jack of the transceiver, refer to FIG.3A, and install a shielded audio
cable from TP900, located toward the front of the transceiver to the Asymod III Line In terminal
5
.
9-
With this configuration:
When SW1 is open (off), the Asymod III is disabled and the transceiver function normally on all
modes as it comes from the factory.
When SW1 is closed (on) the relay is activated and the driver and final are diverted to the
Asymod III and to +12 volts. At this point, the Asymod is enabled and the mode switch must be
set to AM. The transceiver will only transmit on AM via the Asymod III and will be only capable
to receive on FM and SSB.
RL1 (de-energized) = stock operation
RL1 (energized) = Asymod III enabled
SW1 open = stock operation
SW1 closed = Asymod III enabled
