Add these options to your Sienna for peak performance
Option 102. Internal Antenna Tuner Kit. Handles 100W. A switched-L-style matching net-
work tunes 6-800 ohm antenna impedances via the antenna A/B SO-239 antenna connectors at
full rated power. Not intended to match long-wire antennas without baluns. The kit consists of
relays, toroids, Polythermaleze magnet wire and capacitors that you add to the DCD/Tuner board.
No additional firmware to load. Just add the parts and you're ready to go. Each of the five VFO-A
memories on each band maintains current tuner settings. Sienna includes a manual mode as well
as automatic mode, allowing you to control the inductance and capacitance yourself, and to place
the capacitor on either side of the inductor. Once you have found a setting you like, you can save
that setting in memory. Setting are memorized for every 32kHz of spectrum, independently for
antenna A and B. Requires transmitter option. Kit, 1 lb...………………….………...…$190.00
Option 101. 10W Transmitter. Add this 10W 1.8MHz-29.7MHz transmitter (software limited to bands appropriate for your
license) to the S-100 or SF-100 Sienna receiver at any time to turn your receiver into a transceiver. (Included in all transceiver
models.) Balanced mic input and line level input. 3-band parametric audio equalizer. 12th order 2.8kHz crystal filter for SSB,
7th order 5kHz filter for AM/ESSB. Also includes an RF speech processor. Push-pull finals with five bands of toroid filtering
produce a clean output signal. Includes mic input, PTT and linear control outputs. Cannot be used outside the Sienna enclosure.
Requires internally generated control signals and local oscillators. Also includes power meter circuitry for DCD/Tuner board.

Option 104. 100 Watt Output (CW/SSB) Power Amplifier. Also
provides 25W carrier power on AM and FM. Mounts inside the Sien-
na. Fuse and fan protected. Thermistor detects heat rise and increases
fan speed when necessary. Cannot be used outside the Sienna enclo-
sure - requires built-in firmware and control lines. Uses two
2SC2879A RF power transistors in push-pull. Requires transmitter
option. Kit, 3 lbs……………………..……..…………..…….$450.00

Sienna now includes a general coverage bandpass filter module. This was previously a $285 option. We found a way to
lower our cost of this option and since almost everyone ordered Sienna with it, we have now included it standard. This
feature provides 11 bands of filters for the front end. Our unique Passive Signal Boost (PSB) feature also allows you to
bypass these filters, which can provide about 5dB less loss at the expense of additional noise from the wider bandwidth
signals entering the receiver. Low pass filters are always engaged, so there is some wide filtering even with the bandpass
filters bypassed.
