Your new Sienna HF Receiver/
Transceiver represents the perfect
integration of computers and ra-
dio. It’s not just a radio and
with its companion Sedona not
just a PC. In fact if you don’t
like PCs you don’t have to have
one!
Some “software-defined radi-
os” (SDR) require you to have a
PC either internal or external
because after converting the radio
spectrum into digital samples
that data is passed over a high
speed link to a PC for processing.
Sedona’s PC is totally optional
because we know that some of you
like PCs and some do not.
Sienna uses a triple conversion
receiver. By “up-converting” the
entire 0-54 MHz spectrum to 70
MHz it becomes possible to easily
filter out the mixing products
resulting in excellent image re-
jection. In addition there are no
dead spots in the shortwave bands
which is a necessary side effect
of down-conversion radios.
At 70MHz it is not currently pos-
sible to have narrow crystal fil-
ters) - they are just too expen-
sive. But Inrad manufactures an
excellent 6-pole crystal filter
for the Yaesu FT-1000MP that Sien-
na also uses. At 4.5kHz it is
still excellent for good AM copy
while providing much better block-
ing dynamic range than you would
get with a wider filter.
Sienna is also one of the only ra-
dios on the market with a com-
pletely separate transmitter and
receiver. There are no shared com-
ponents or oscillators. Thus full
-duplex operation such as that
used in satellite operation is
possible. Full duplex also allows
you to monitor your signal. A sep-
arate transmitter and receiver and
it also allows true cross-band/
cross-mode operation.
Introduction

Page 5
Modularity is another of Sienna’s
features. The chassis has six com-
partments — power receiver
transmitter 100W amp control and
auxiliary. This affords excellent
shielding and also provides easily
serviceable components. Should the
transmitter ever need service it
can be removed without disturbing
anything else.
Cooling in Sienna is also im-
portant. Two central fans pull air
in from the front sides cooling
the display and controller chips
passing it across the transmitter
amplifier and DC power distribu-
tion boards and exhausting it out
the back. Thermistors regulate the
fan speeds.
Finally a lot of attention has
been paid to ergonomics. Sienna’s
controls are grouped by function
and dual functionality is used
sparingly and carefully. The most
common controls are on the front
panel while the ones used less
often are in the first level menu
(which is always on the display—
AGC NB VOX/PTT Antenna selec-
tions). Other less often used
functions are in a very simple
menu system. An external 12-button
keypad is supported (and built-in
to Sedona) which allows easy ac-
cess to memories CW buffers and
one-button-per-band bandswitching.
Sedona’s internal PC adds all the
features of a PC (logging web
connectivity USB rig control
digital modes mic processing
etc.) that are often handled in
other rigs by the use of expensive
“rig interface” boxes. With Sedo-
na’s internal PC you don’t have
nearly the mess of external wires
that you would have with an exter-
nal PC making portable operations
much more convenient. And in a
matching case to Sienna!

Back Panel
1. Keypad. Connect a 12-button keypad such as the Yaesu FH-2 to this
connector. See Appendix B for details on how to build your own.
This allows you to change bands with a single keypress use the
memory features and select a band directly instead of using band
up or down controls. This connects directly to Sedona or to a aesu
FH-1 or FH-2 keypad.
2. Key. The manual and paddle jacks are connected in parallel with
those on the front panel and are both active simultaneously so that
you do not have to turn the keyer off to use a straight key or ex-
ternal keying device.
3. Audio. Line-in and Line-out are stereo 600 ohm audio inputs and
outputs that can be connected to the sound card on a PC or other
audio devices. Line level is nominally 200mVrms.
4. 455KHz IF Out. This is a large bandwidth output centered at 455KHz
that can be connected to a spectrum analyzer or panadapter to view
signals on the current receive band.
5. RX Antenna. This BNC connector allows you to run the receiver from
an antenna that is not connected to the transmitter. It is protect-
ed from static by a gas discharge tube but not against high trans-
mitter power. Maximum input power is 1mW (0dBm).
6. ALC In (RED). This phono connector allows 0 to –5VDC input from an
external linear amplifier to control the output level of the inter-
nal 100W amp. Higher negative voltages produce lower output power.
7. PTT In ( REEN). This phono connector provides a push-to-talk input
that is wired in parallel with the PTT pin in the front panel mic
connector. Ground the input to enable the transmitter. It is pulled
up internally to 5V with a 1K resistor.
8. Mic In (BLUE). Unbalanced audio from this phono connector is mixed
with the front panel microphone connector or with the internal line
13 14 15 16 17

Page 7
signal from the Line In connector. The input impedance is about 10K
ohms.
9. Antenna A. This SO-239 connector is the main transmit/receive an-
tenna. It is protected from static discharge by a gas discharge
tube.
10.Antenna B. This SO-239 connector is a secondary antenna. A menu
item lets you select antenna A or B. It is protected from static
discharge by a gas discharge tube.
11. ND. This is chassis ground. Connect this to a good earth ground.
12.DC In. These Anderson Powerpole connectors are the main DC Input.
Connect these to a clean source of DC voltage from 11-15VDC. The
transmitter will operate from 12-15V. The receiver can operate over
the full range.
13.RS-232C I/O. Connect this serial port to a PC or to another Sien-
na.
14.Exhaust holes. These holes serve as exhaust for the internal fan.
Do not block these holes.
15.Linear. 8-pin mini-DIN connects to linear amplifier
16.Exhaust plate. This bracket provides exhaust for the fan that cools
the DC power distribution board and optional 100W amplifier. Do not
block the exhaust holes.
17.Fuse. This 25A fuse is inline between the main power input and the
optional 100W amplifier. If the amplifier is not installed this
opening can be replaced with a hole cover or used to bring cables
in and out if you wish to use the compartment to hold a battery or
other device.

Front Panel Controls
1. RF ain (RF or Radio Frequency ain). This control overrides the
automatic gain control (AGC) of the Receiver’s Intermediate Fre-
quency (IF) amplifiers. In its CW (clockwise) position the AGC has
full control over the gain. As you rotate the control counter
clockwise (CCW) it reduces the available gain. This control is
usually left in the CW position unless extremely strong signals are
present. It can also be used to reduce sensitivity so that only
stronger signals are heard which can help during contests.
2. Preamp1. This switch activates the first of two available RF ampli-
fiers. On lower frequencies below 10MHz this amplifier is often
not needed. Above 10MHz it is not needed when band conditions are
excellent. It is useful for pulling out very weak signals on a fad-
ing band.
3. Pre2/Atten. This switch activates the second of two available RF
amplifiers only if the Preamp1 switch (see previous item) is
pushed. If Preamp1 is off this button serves as a 10dB attenuator.
If you use the attenuator and then push the Preamp1 button the at-
tenuator is disengaged and both preamps are turned on. You should
only need both preamps to pull out very weak signals as this much
RF gain increases distortion on strong signals.
4. Headphone volume. This control adjusts the gain of the headphone
audio amplifier. It can be adjusted separately from speaker volume.
5. Headphone jack. Plug low impedance stereo headphones into this
3.5mm minijack connector.
6. AF ain (AF or Audio Frequency ain). This control adjusts the
gain of the speaker audio amplifier. Speaker volume can be adjusted
separately from the headphone volume.
7. Mute. This button mutes all sources both the internal receiver and
any audio from the line in jack.
8. Dual. This button activates dual receive. In this mode input from
12 13 8 9
4 5 6 1 2 7 10 11 3

Page 9
the stereo Line In jack on the back panel is fed to the speakers
and the internal receiver is fed only to the right speaker. This
allows you to listen to one receiver in each ear. In order to feed
a mono source such as a receiver to the left channel only you must
connect the left channel to the external receiver but not the
right. This can be done by using a mono minijack plug in the stereo
minijack.
9. FM Squelch/NB Thresh. In FM mode, this control sets the level at
which FM signals are quieted (squelched). In other modes this con-
trol sets the noise blanker threshold if the noise blanker is
turned on.
10.Adjust. This control consists of a rotary pulse generator (RPG) and
a pushbutton switch. The function of the RPG and the switch depend
on the 8-position switch immediately below it (11).
11.Multipurpose switch. This switch selects up to 8 different modes
for the RPG control that is above it (10). In the CCW position it
enables the RPG to change which IF filter is selected. Pushing the
RPG knob switches back and forth between the 9MHz and 455KHz fil-
ters and a * is placed next to the currently selected set in the
display. The width of the trapezoids in the display changes to give
a visual indication of the bandwidth of the selected filter. Note:
when you change bands or modes the previously saved filter is au-
tomatically selected. In position 2 the switch allows the 9MHz or
455KHz passband (whichever is selected) to be shifted right or left
50Hz per detent. Position 3 selects the notch filter when the ad-
just button is pushed. Position 4 is reserved for future use. Posi-
tion 5 allows the pushbutton to start or stop scanning functions.
Position 6 of the switch accesses the CW buffers (which are set in
menu options). The rotary control selects one of the ten buffers
and the pushbutton starts the buffer. Position 7 is for memory
buffers. Rotating the RPG selects a memory and the pushbutton then
moves it into VFO A. Position 8 is the “Birdcage” labeled “BC”. In
this position rotating the Adjust knob shifts the 1st IF left or
right by 50Hz per click. Pushing the button resets all IF shifts to
0. The birdcage is very useful for removing spurious receiver mix-
ing products (“birdies”) that are present in all superhet receiv-
ers.
12.Microphone jack. This connector is wired for a Yaesu compatible mi-
crophone. An external adapter is required for use with other micro-
phones.
13.Mic ain. This control adjusts the microphone gain. Use it with the
ALC meter indication on transmit to keep from overmodulating the
final amplifier.

Page 10
14.Proc/CW Spot. In SSB mode this button activates the RF speech pro-
cessor. In CW mode this button disables the transmitter and allows
the keyer (internal or external) to be used as a SPOT control. To
use this function press the key and turn the Pitch control (20)
until the sidetone frequency matches that of the received signal.
This assures that you are transmitting on the same frequency as the
station you wish to communicate with. CW SPOT mode can also be used
for code practice since no signal will emanate from the transmit-
ter. It is useful to press the Mute button in this mode too to
eliminate receiver noise. You do not need to change the RF Power
control when using CW SPOT.
15.Proc Level. This control adjusts the compression level. Use on SSB
with the Compression scale on the meter to keep speech compression
less than 10 dB.
16.Tuner. This button activates the optional internal Antenna Tuner.
The tuner memory saves up to 30 settings and allocates them into
32kHz of spectrum from 0 to 30MHz on a per-antenna basis (A or B
antenna). If a band segment on a particular antenna has never been
tuned then if this switch is on the first time you transmit on
that band segment a tuning operation will occur and the settings
will be memorized. When the switch is off the tuner is bypassed. A
menu option allows you to reset the tuner settings or force a tune
operation on a band segment that was alreadt tuned. In that menu
you can also see what the tuner selected and change the inductance
and capacitance manually.
17.RF Power. This control adjust the transmitter power level from 0 to
11.8W (118W if the 100W amp is present and enabled). Note that this
is “requested” power. Actual power is measured in real-time by the
ALC (Automatic Level Control) firmware and will be as close as pos-
sible to this value. If the “ALC Threshold” menu setting is “0”
the display reads “P-Rel” which means that the RF Power control is
a relative uncalibrated value.
18.Sidetone Volume. In CW mode this control adjusts the volume of the
14 15 16 17 26 32 27 30 31 23 24
25 28 29 18 19 20 21 22

Page 11
CW sidetone. Sidetone volume is also affected by the main speaker
and headphone volume controls.
19.Dot Weight. This screwdriver-adjustable pot sets the ratio of dots
to spaces for the internal keyer.
20.Pitch. In CW mode this control sets both the CW pitch (tone) and
the receiver passband. Use with the CW SPOT button (14) to zero
beat the transmitter to that of a received signal.
21.Dash Weight. This screwdriver-adjustable pot sets the ratio of
dashes to spaces for the internal keyer.
22.Speed. In CW mode this control adjusts the speed of the internal
keyer from 5-65WPM.
23.Full Break-In. In CW mode this button activates full break-in.
This means that the drop-out time after you release the key is
changed from that used for Semi-Break-in to a much faster value
allowing you to hear between the dots as you send. This is often
used to avoid stepping on another operator’s toes by transmitting
at the same time. However some operators find it unsettling to
listen to the receiver while transmitting. The value of drop-out
time is settable in a menu item for both Semi and Full break-in
modes. Default is 1 second for Semi break-in and 10ms for Full
break-in.
24.Key jacks. These jacks are both active at the same time. You can
plug a straight key or external keying device into the manual key
input and paddles into the other. Thus there is no need to turn
the keyer off when switching to another keying device such as a PC.
25.Menu. This button activates the menu. See the detailed description
of menu selections starting on page 16.
26.Page/Mode. If the menu button is NOT lit this button allows the
small tuning knob to cycle through all available modes (CWUSB
CWLSB USB etc.). If the menu button IS lit this button allows
the small tuning knob to cycle through all the available pages in
the menu. When menu is first selected the button comes on by de-
fault to allow you to quickly find the desired page. Once you find
it rotating the large tuning knob turns it off. To go to another
page press the Page/Mode button again.
27.Fast/Lock. This button changes the rate at which the tuning knobs
change the frequency. If enabled in a menu item it also causes the
dials to lock after a period of inactivity.
28.Clear. This button clears a RIT (Receiver Incremental Tuning) or
XIT (Transmit Incremental Tuning) offset. If XIT and RIT are both
off this button enables SPLIT mode which allows you to set the
transmitter frequency and mode independently of the receiver. The
display shows the current setting of VFO B which is used only for
the transmitter. In SPLIT mode pressing the A>B (XIT) button cop-
ies the displayed frequency (VFO A) into VFO B. Pressing A<>B (RIT)
swaps the VFO frequencies and modes.

Page 12
29.XIT. Transmit Incremental Tuning. With RIT and SPLIT off this al-
lows the small tuning knob to be used to adjust the transmitter
frequency up to 16MHz from the receive frequency. The mode (USB
LSB etc.) is not changed. See (27) for an alternative mode for
this button. If the BAND button is pushed this button changes
bands to the next higher band.
30.RIT. Receiver Incremental Tuning. With RIT and SPLIT off this al-
lows the small tuning knob to be used to adjust the receiver fre-
quency up to 16MHz from its original frequency. The mode (USB LSB
etc.) is not changed. See (27) for an alternative mode for this
button. If the BAND button is pushed this button changes bands to
the next lower band.
31.BAND. In this mode the large tuning knob is used to change bands.
There are five VFO A frequencies per band; when you change bands
the last used VFO A frequency is used. If you have connected an ex-
ternal keypad such as the Yaesu FH-1 to the Keypad input on the
back panel you can also change bands directly without pushing the
BAND button. There are 10 bands (160-80-60-40-30-20-17-15-12-10)
and five VFOs each per band. The value of each is shown as bbb-vv
such as 160-1. When the BAND mode is selected the XIT and RIT but-
tons can be used as band up/down functions. They are labeled with
yellow up and down arrows corresponding to the yellow BAND text as
a visual reminder.
32.Large and small tuning knobs. These knobs are used to change fre-
quency when not in MENU or BAND modes. When RIT and XIT and SPLIT
are not on the large knob is used for fine tuning and the small
knob for coarse tuning. The FAST button changes the rate of both
knobs. In MENU mode the large knob selects a menu item on the cur-
rent page and the small knob changes its value. In BAND mode the
large knob changes bands and the small knob selects VFO A memory 1-
5 (and you will see the number change that is located right above
the “kHz” in the display). When RIT or XIT or SPLIT are on the
small knob changes the increment or SPLIT frequency and the large
knob changes the receive frequency.

Basic Operation
Unlike many modern transceivers/receivers that have a multitude of
buttons and knobs which look flashy but which you seldom use Sienna
has four simple modes of use each giving you more and more flexibil-
ity without cluttering up the front panel. These are:
1. Functions used most often have dedicated buttons and knobs
2. Functions used less frequently are in easily-accessed menus with
the more commonly used items always visible
3. Functions requiring a lot of “horsepower” have rudimentary front
panel access but are best accessed via a PC or external keypad
such as use of the many memories
4. An external 12-button keypad compatible with the Yaesu FH-1 or FH-2
provides direct band selection and easy memory and CW buffer usage
REMOTE CONTROL
If your Sienna has no front panel all functions are accessed via the
RS-232 port for which a simple terminal emulator program such as Hy-
perterm can be used. More elaborate programs are available such as
Ham Radio Deluxe or DXLab Suite that are compatible with multiple ra-
dios. We also plan to offer a simple program that is tuned for use
with Sienna. It is still instructive for the “front-panel-less” user
to become familiar with the front panel functionality since most RS-
232 commands were designed to emulate front panel controls.
Many PCs no longer have RS-232 ports but converter cables from RS-232
to USB are easy to obtain. Sienna works fine with these adapters.
Please refer to the command listing in Appendix C of this manual for
details on the available commands.
CONTROL ROUPS
Controls are grouped into four sections: Receiver Transmitter Tuning
and Keyer. Only one set of controls in the Receiver group actually af-
fects the transmitter and that is the multifunction 8-position switch
and the “adjust” knob/switch above it. These controls access the fil-
ter selection IF shift memory and scanning for the receiver and CW
buffers for the transmitter.
The Tuning section consists of the main tuning knob the secondary
tuning knob and the five buttons adjacent to the secondary tuning
knob. These provide rapid tuning modes band changes RIT XIT and

Page 15
SPLIT functions and a dial lock function.
Keyer controls allow complete access to the keyer including QSK (full
break-in) operation dot and dash weighting volume speed and pitch.
The pitch control along with the SPOT control (in the transmitter con-
trol section) is also useful for zero-beating signals on CW.
THE MULTI-FUNCTION SWITCH AND ADJUST KNOB
The receiver group has an 8-position switch and above it a rotary
pulse generator (RPG) that has 32 steps per revolution. The RPG also
has a pushbutton switch built into it. These two controls work togeth-
er to give you an amazing amount of functionality in a small space.
The switch selects a function: Filters (top position 1) IF shift
(2) IF Notch (3) reserved (4) scanning (5) memory (6) and CW
buffers (7). Position 8 (BC) is the “Birdcage” and allows you to
shift the first IF back and forth to eliminate birdies in the receiv-
er. More detail about these functions is found in the section on how
to use the receiver.
METERIN
There are two meters. The left meter shows transmit functions includ-
ing final amplifier voltage and current driver current SWR forward
and reflected power RF compression and ALC. The right meter shows S-
units from 0 to 9 (calibrated at approximately 6dB per unit with S9 =
-73dBm = 50 microvolts) and in dB above S9 up to 45 dB over 9 (-28
dBm). In FM the S-meter shows a relative signal strength indication.
Since the transmit meter has multiple scales it is helpful to know
which one is selected. A menu option lets you select this and the
chosen selection is shown in the upper right corner of the vacuum
fluorescent display (VFD) along with an arrow pointing toward the me-
ter such as “Fwd Pwr ->”.
MENU
The menu is accessed by pressing the MENU button. (Remote control com-
mands are available for most menu functions except those that relate
to use of the front panel itself such as display brightness.)
The menu consists of two sections. The mode (e.g. “USB”) and all
functions along the bottom row (AGC Noise Blanker PTT/VOX Antenna
and RF Power) are always displayed. These are things you are likely to
need to change most often so they are easily accessible no matter

Page 16
what else is showing on other menu pages. (RF Power is accessed using
the RF Power control rather than a menu item.)
The second menu section is a series of “pages” consisting of up to
five lines of parameters.
To edit or view a parameter press the MENU button. Notice that the
“PAGE/MODE” button also lights up indicating that paging is active.
This means that when you rotate the small tuning knob either direc-
tion different pages will be displayed on the right half of the dis-
play. Once you have located the page containing a parameter you wish
to change rotating the large tuning knob will select one of those
items and highlight it. When you rotate the large knob you will also
notice that the PAGE/MODE light goes out indicating that you are now
able to edit entries on that page. Once you have selected an item you
can then change its value by turning the small tuning knob.
If you wish to go to another page once you have edited an entry on the
existing page simply press the PAGE/MODE button to re-enable paging.
To exit menu mode press the MENU button again.
Why is the PAGE/MODE button called this? If you are not in MENU mode
and you push just this button you can change just the mode of the ra-
dio (CWUSB CWLSB USB LSB etc.) by turning the small tuning knob.
Push this button again to turn it off. This is a faster way to change
modes than going into the menu although both methods can be used.
Menus are described in detail in a separate chapter.
DIAL LOCK
One of the menu settings allows the tuning knobs to be
“locked” (meaning that turning them will have no affect on frequency)
after a period of inactivity. When enabled the FAST/LOCK button turns
this feature on. This function is doubled up with the FAST tuning con-
trol since it is likely that if you are tuning fast you aren’t going
to need to lock the dial. Thus even if dial lock is active pressing
the FAST/LOCK button puts you into FAST tuning mode first. Press the
FAST/LOCK button again to deactivate the lock function.
10-SECOND RULE FOR SAVIN THE CURRENT STATE

Page 17
The radio constantly monitors parameters that must be saved in non-
volatile (i.e. permanent) memory when the radio is turned off. Howev-
er when you are actively using the radio it is unnecessary (and un-
desirable) for the microprocessor to save the current state infor-
mation to its memory constantly. Anytime something that must be saved
is changed a 10 second timer is started. If nothing else changes
within that time all changed state information is written to memory.
The timer is re-started if anything does change within that 10 sec-
onds. If the timer “times out” and any of the memory locations has
changed data in it a small dot appears for one second in the display
above the “z” in “kHz” to indicate that state information has been
saved.
As a result if you turn off the radio before waiting 10 seconds for
the current settings to be stored it may not return to the exact fre-
quency or mode you last used. Be sure to wait until you see the dot in
the display before turning off the rig unless it has been idle for
longer than that.
KEYPAD
The 12-button keypad operation is described in Appendix B. Although
there are many fast ways to change bands and there is front panel ac-
cess to the CW buffers and memories some like to go from band to band
with a single button push or access memories and CW buffers more easi-
ly. This keypad is easy to make yourself or you can buy the one made
by Yaesu. The functionality of the buttons is not identical to that of
Yaesu rigs though so you may want to remove the overlay and make your
own. The DZKit Sedona has a compatible keypad built in.
FIRMWARE UPDATES
A utility program is provided on the flash drive included with all
kits called “Megaload”. Install it then connect Sienna’s RS-232 port
to the computer. Run Megaload putting the “sienna_rev_xxxxx.hex” file
in the top box. If the EEPROM data also needs updating put the
“sienna_rev_xxxxx.eep” file in the second box. (Replace “xxxxx” with
the revision code such as B0221). Downloading a new EEPROM file will
reset all cal constants to default so be sure you have written down
all cal constants for your radio so they can be restored! These files
can be found on the DZKit web site or we can email them to you. Just
ask for the latest version!
Once Megaload is running select the Com port and baud rate (9600).
Leave all checkboxes unchecked. Once it’s all set up Megaload should

report in the Status box “Ready. Waiting for target”. Go into the
menu and find the page with the firmware rev info. At the bottom is a
line that reads “Re-program uP:”. Change it from No to Yes. Wait about
10 seconds and the download should start automatically. When done
Sienna will re-start. If you have never connected Sienna to the PC be-
fore it is wise to do so first and run a terminal emulator like Hy-
pertrm just to make sure you can talk to it to verify cable connec-
Megaload ready to download. Note that the Target information is shown
as “xxxx”. Once you start the download (see next page) the processor
information is read from Sienna into Megaload and displayed as shown
in the picture on the next page.

Once you have set up Megaload and
connected Sienna to the PC go in-
to Sienna’s setup menu and locate
this page. Select “Re-program uP:”
and change “No” to “Yes”. Wait 10
seconds and the download as
shown below will start.”
As data is downloaded to Sienna the page number of the binary file is
reported in the Messages box. If no EEPROM file is specified the mes-
sage “No eeprom file… Open file first!” appears in the Status box. If
you chose not to download it this is OK. Otherwise specify the
“sienna_rev_xxxx.eep” file in the 2nd box at the top and that data
will also be downloaded.

A quick tutorial on receiver theory
Sienna uses a triple conversion receiver with three intermediate fre-
quencies (IFs): 70.455 MHz 9.0 MHz and 455 kHz. By “up-converting”
the entire 0-30 MHz spectrum to 70.455-100.455 MHz many spurious by-
products of the mixing process are eliminated.
For example if you are listening at 14.0 MHz the VFO frequency is
set to 70.455 + 14.0 MHz = 84.455 MHz. This means that the first RF
mixer will generate outputs at the sum and difference of the two fre-
quencies (84.455 +/- 14.0 MHz): 70.455 MHz (the difference) and 98.455
MHz (the sum). The first IF filter (called a “roofing” filter) only
passes a small portion (less than 5 kHz) of spectrum around 70.455
MHz so the sum product at 98.455 MHz and other mixing products are
completely eliminated.
As it turns out a 154.91 MHz signal would also create an output at
70.455 MHz (154.91—84.455). This is called the “image” frequency. Be-
cause the up-converted spectrum is so high in frequency such signals
are easily filtered out by RF bandpass and low pass filters before the
signal can reach the mixer resulting in excellent image rejection.
The small downside to this is that narrow filters cannot be used at
70.455 MHz because they would be very expensive. Sienna uses a 4.5 kHz
roofing filter standard which provides excellent performance when
combined with the many filters available at the 2nd and 3rd IF.
Controls
Since Sienna can be built either with or without a front panel the
following descriptions refer to the front panel functions and then
call out the equivalent remote control command in brackets such as
[MD] for the mode command. Refer to the RS-232 command chapter for de-
tails on the command structure.
When using the front panel there are a number of parameters that can
only be set in the menu. Such parameters are referred to with a prefix
of MENU and the parameter in quotation marks such as MENU: “AGC-
Slow”.
