Compartmentalized for isolation, strength and expansion
Sienna is compartmentalized. The controller/front panel, DC power conditioning, receiver, transmitter and amplifier are all in different com-
partments. In addition, there’s a small 4 x 6 area near the back panel called the “auxiliary compartment”. All are available for your use depend-
ing on which options you have installed. For example, if you have a receiver model, the amplifier, transmitter and auxiliary compartments are
available. If you have a 10W transceiver, the amplifier and auxiliary compartments are available. If you have a 100W transceiver, the auxiliary
compartment is available. If you’re an experimenter, you will find the availability of these compartments and access on the back panel very
handy.

The DC power and tuner tray rotates up for access to
the 100W amp. The 10W transmitter can be lifted out
of its compartment. These are just two of the many
features that make it easy to build and service your
Sienna.
Built-in serviceability makes assembly and troubleshooting easy!
This switch puts a
70dB attenuator in
the transmit oscilla-
tor path, allowing it
to be used as an S9
signal source for
receiver S-meter
calibration.
Menu options allow you to do calibration and
run tests. For example, when you turn on the
first item in this menu (DspFrq = TXVFO),
the transmitter’s VFO is set to the display
frequency instead of its normal value. This
allows you to use it as an RF signal generator
to test or troubleshoot the receiver.
