The MIRAGE B1016 represents the latest in 2 Meter
Power Amplifiers. It incorporates features that make it the
most useful and versatile amplifier available today. The
B1016 has a built-in receive preamp, variable SSB delay,
remote keying and complete remote control when using the
optional RC-1, Remote Head. It will amplify both FM and
SSB signals. It has built-in thermal protection to prevent over
heating.

INSTALLATION:
The B1016 may be mounted by using the brackets supplied.
The B1016 must have adequate ventilation around the
heat sink. Use of #8 or larger wire to connect the B1016
to the battery is recommended. Use good quality 50 Ohm
co-ax, between the radio and the B1016. RG-8U or the
equivalent should be used between the B1016 and the antenna.
The antenna should be matched, to better than 1.5:1
for best performance. SWR less than 3:1 will degrade system
performance. SWR greater than 3:1 may cause damage to
the amplifier voiding any warranty.
Front Panel Functions:
- POWER-ON/OFF-
- This switch turns the power amplifier
ON and OFF.
- SSB/FM-
- Selects the relay time delay for the mode of
operation. In either the SSB or FM position, the amplifier
is still biased for linear operation.
- PREAMP-ON/OFF-
- Turns ON and OFF the receive
preamp. This works independent from the Power
ON/OFF switch. When either the Preamp or Power
Amp is turned on the Amplifier automatically switches
the antenna using its internal circuitry. If it is desired
to key the antenna relay externally a connection is
provided on the rear panel (see Rear Panel Functions).
- LED (Power On)-
- This LED will go out if the amplifier
over heats. It will come back on when the amplifier
has cooled.
Rear Panel Functions:
- "RADIO"-
- This connects to the transmitter or transceiver.
- "ANT"-
- This connects to the antenna.
- RCA JACK-
- This is for Remote Keying-Connect to
ground to key the antenna relay.
- 6 PIN REMOTE CONNECTOR-
- The RC-1 Remote
Control Head connects here.
PRECAUTIONS:
- Output Power-
- The B1016 puts out enough power to
cause heating of the antenna coax. RG-8 or equivalent
is recommended between the amplifier and
the antenna.
- Heat Sink Temperature-
- Along with high power output
comes the possibility of high heat sink temperatures.
The B1016 must be mounted where air can
circulate over the heat sink. The B1016 has a built
in thermostat that will turn it off at 170 degrees F.
The amplifier will not come back on until the
temperature drops to 140 degrees F.
- Input Power-
- Input power should not exceed 15 to 18
Watts. Higher power than this may cause failure
of the input transistor. This will VOID ANY WARRANTY.
Internal Adjustments:
- "SSB DELAY"-
- This allows the relay delay to be adjusted
to any desired delay. Access to this adjustment
is through the hole in the left side of the
cover, behind the front panel. Use a small screwdriver
to adjust the control.
- "INPUT" and "OUTPUT" MATCH (See Warranty).
-
These are factory adjusted and do not normally
require adjustment. The cover must be removed
to make these adjustments. Connect an SWR meter
between the radio and the input to the amplifier.
Adjust the "INPUT" trimmer capacitor (marked
yellow) for lowest SWR. Connect a power meter to
the output and adjust the "OUTPUT" trimmer capacitor
(marked green) for maximum output at
minimum DC current drain.
- Preamp Tuning-
- These trimmers are factory set for the
best gain and noise figure. They should not be
re-adjusted unless connected to the proper equipment
to set the noise figure.
- Fuse-
- A 35 Amp fuse is located under the cover on
the P C Board. Should the fuse "blow", determine
the cause before replacement.
IN CASE OF DIFFICULTY:
- Check for loose antenna or B+ connections.
- Check S.W.R.of antenna.
- Look for bad or lossy co-ax.
