Page 4 Introduction Your new Sienna HF Receiver/ Transceiver represents the perfect integration of computers and radio. 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! which is a necessary side effect of down-conversion radios. At 70MHz, it is not currently possible to have narrow crystal filters) - they are just too expensive.
Page 5 Modularity is another of Sienna’s features. The chassis has six compartments — 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 important.

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.

This control overrides the automatic gain control (AGC) of the Receiver’s Intermediate Frequency (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.
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 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 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.

Page 14 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 flexibility, 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.
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 control 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.
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 direction, different pages will be displayed on the right half of the display.
Page 17 The radio constantly monitors parameters that must be saved in nonvolatile (i.e., permanent) memory when the radio is turned off. However, when you are actively using the radio, it is unnecessary (and undesirable) for the microprocessor to save the current state information 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.
Page 18 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.
Page 19 Once you have set up Megaload and connected Sienna to the PC, go into 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 message “No eeprom file… Open file first!” appears in the Status box. If you chose not to download it, this is OK.
Page 20 The Receiver A quick tutorial on receiver theory Sienna uses a triple conversion receiver with three intermediate frequencies (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 byproducts 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.
Page 21 Major receiver functions include: Frequency (including “band”, VFO’s within a band, incremental tuning, memory usage, split mode, tuning rate, resolution) Mode (AM, CW, SSB, etc.
Page 22 in a menu page. If the scan increment is set to “chn”, scanning starts at the selected memory channel and stops at the end memory channel, then cycles back to the start channel. If the scan increment is a number, the frequency is incremented by the selected amount (MENU: “Freq inc(Hz)” = 10 Hz, 100 Hz, 1 kHz, 10 kHz, 15 kHz, 20 kHz, 25 kHz or 50 kHz) until the frequency in VFOB is reached. (Use the SPLIT function to set VFO B.
Page 23 Changing the frequency [FA, FB, RU, RD, RC, XU, XD, XC] There are several displayed frequencies depending upon use of Split, RIT and XIT modes. It helps to remember that the large font that is always in the display is ALWAYS the receive frequency. It is also the transmit frequency unless you are using RIT or XIT or Split. When Sienna is powered on for the first time, the frequency is set to 14.000 MHz.
Page 24 mode transmit antenna receive antenna preamp/attenuator • • • Press the BAND button and rotate the large tuning knob to step from band to band. The last used VFO setting (1-5) on that band will be selected. Press the desired band button on the 12-button keypad. (See Appendix B) Press the BAND button and then press the Up or Down arrow buttons (same as XIT and RIT). Note that pressing BAND disables RIT and/or XIT if they were enabled.
Page 25 also change the mode by pressing the MENU button, rotating the large knob until the mode is highlighted and then change it by turning the small tuning knob. Receiver Incremental Tuning (RIT) [RC, RD, RT, RU] RIT (and transmit incremental tuning, XIT, discussed in the transmitter section) is typically used for three purposes: 1. To tune in a signal that is slightly off frequency without changing your transmit frequency 2.
Page 26 in the “always present” menu items along the bottom of the display. The signal threshold can be changed by turning the “NB Thr/FM Squ” knob. Three fixed, retriggerable pulse widths of 30us, 66us and 2ms can be selected. The display will indicate “off","med","long", or "max". The 4 “off” states are needed because the pulse width can be changed by remote control without turning the blanker on. So, off means off/fast, off2 means off/med, off3 means off/long and off4 means off/max.
Page 27 ceive antenna. This is indicated in the display as Rx-R for the receive antenna, or Rx-T for the transmit antenna. The transmit antenna is displayed as Tx-A or Tx-B.
Page 28 The audio gain controls (one for the headphones and one for the speakers) affect the amount of audio reaching your ears. There is plenty of gain there to cause distortion on loud signals, but there are times when weak signals need to be cranked as high as possible.
Page 29 you can select position 8 (the “birdcage”) and shift the 1st IF back and forth 50 Hz per click. This often eliminates the occasional internally generated spurious mixing product (“birdie”) without bothering the received signal noticeably. On CW, you can select either the upper or lower sideband on which to listen to the signal. If an interfering signal is too close on one sideband, it may not be audible on the other. Simply select CW(USB) or CW(LSB) as the mode.
Page 30 AM signals such as pulse interference. That is why the NB Threshold control is shared with FM. In FM mode, you must also enable the FM circuits by enabling IFOut/FM in the menu. See menu photo below. Although Sienna is an HF Receiver/Transceiver, it does have a transverter output, allowing it to be used on VHF bands where FM is more prevalent. See the section on transverters for more information. Line In Stereo sources can be played through Sienna’s rear panel Line In minijack.
Page 31 This causes the master to send its frequency out to the slave whenever the receive frequency is changed. (The “FA” command is used for this.) Note that the slave should first be set to the same band. It is not essential, but may be confusing if the slave is on 40M when it is commanded to change frequency to one on 20M. The displayed band information does not change. You can then change the slave frequency as usual with its controls. The slave Sienna must have this function off.
Page 32 The Transmitter Sienna’s transmitter is controlled via the following front panel functions (relevant RS-232 commands shown in brackets): • • • • • • • • Microphone (mic) gain [MG] Parametric equalizer setup RF speech processor on/off and CW spot [PR] RF speech processor level [PL] RF power [PC] Split — Separate transmitter and receiver frequencies and modes [FT] XIT — Transmitter incremental tuning On/Off [XT] — Transmitter incremental tuning Clear [XC] — Resets XIT offset to 0 Down 10 HZ [XD] —

Page 34 Balanced Microphone and Unbalanced Line inputs The audio amplifier section of Sienna’s transmitter consists of components that have very low total harmonic distortion (THD < .01%) and no crossover distortion (which means there is no glitch when audio signals cross 0V going positive or negative). This, along with the balanced mic input cabling and preamp, results in extremely clean and noise-free audio going into the RF sections.
Page 35 cy by 10 Hz if the resolution is set to 10 Hz, or by 1 Hz if the resolution is set to 1 Hz. If the FAST input is also grounded, the frequency is changed by 100 Hz or 10 Hz depending on the resolution. Resolution is not settable via RS-232 commands — the minimum increment is always 10 Hz unless manually set via the front panel (menu item “Disp Res”). The “Fine Step” command is equivalent to the FAST function. (Fine Step actually means that the FAST button is OFF.
Page 36 RF Speech Processor [PL, PR] The RF speech processor compresses microphone audio by amplifying it at its IF (10.7 MHz) and then clipping the waveform. The resulting signal has many harmonics in it, so it is then passed through a filter, which restores the original signal purity. The result though, is a signal with much more “punch”, since low signal levels are increased in amplitude.
Page 37 It is the independent transmitter design in Sienna that makes very high speed QSK on CW possible. Turnaround time from transmit to receive is only 10 ms, about half the length of a dit at 60 wpm. Sienna can thus “hear between the dits” at up to about 70 wpm. A circuit in the receiver and the sidetone generator on the controller prevent audible clicks that can happen when audio circuits are suddenly turned on or off, which also contributes to Sienna’s smooth QSK.
Page 38 of the unwanted sideband. Always listen to your transmitted signal on a monitor receiver (or enable full duplex and listen on Sienna) before making big changes to the default IF shifts. The shift is set in the menu options “Tx Shf (USB)” [CU] or “Tx Shf (LSB)” [CL]. VFO A and VFO B (Split mode) Split mode operation allows the transmitter to be used on a different frequency and a different mode than the receiver.
Page 39 transmit and receive on 28-29.7 MHz, so the transverter must use these frequencies for its IF. Since you may want to display the actual frequency, the menu option "Xverter Freq:" can be used to change the leading digits of the display from 28 or 29 to 50, 52, 54, 144, 146, 22, 224, 420, 422, 424, 426, 428, 430, 432, 434, 436, 438, 440, 442, 444, 446 or 448. Operation on 6M. Sienna was originally designed to use transverters for all VHF and UHF operation.
Page 40 Transmit Audio Equalization You can tailor the speech characteristics of your microphone by adjusting the transmitter’s parametric equalizer. You can change the center frequency and gain of the treble band, and the Q, center frequency and gain of the midrange and bass bands. The chip used is a TDA7418 made by STMicroelectronics, Inc. A datasheet for this part is included on the flash drive. Experiment with the values in the menu to hear the effects.
Page 41 This chunk actually contains tuner data for the range 13959169 to 14024703 Hz. Chunk 428 handles 14024704 to 14057471 Hz, and so on. The tuner saves the chunk number and the L and C values that worked on the given antenna (A or B) in the first available memory location. If memory fills up, entries are overwritten, which will cause new tuning cycles to start on previously tuned frequencies.
Page 42 External amplifiers Sienna’s antenna A or B connectors can be connected to an external linear amplifier. Other connections are via the ALC phono connector and 8-pin DIN connector on the back panel. Connections are as follows: DIN connector: pin 1: 11-15VDC (raw input voltage), 250 mA max current (fused*) pin 2: TXGND.
Page 43 ALC phono connector: Amplifier ALC output, 0 to –5V. (Sienna INPUT) It is not necessary to use the ALC input. The purpose of this input is to allow the amplifier to regulate the power level of Sienna to maintain a constant signal level. However, this can cause the transmitted IMD to be worse due to the “AMing” effect of changes to the RF power. As a result, some prefer to do this manually. If you want to enable use of the external ALC, select menu option “Tx/Amp” and select “Int 100W+Ext”.

Page 73 CW KEYING Set: KY <24 chars>; Read: KY; Response: KYx; x = 0: Keyer ready x = 1: Keyer not ready You must wait until you read a “KY0;” response before sending a new buffer. There is a space after the KY in the set command. This space is not transmitted. Note: Sienna’s 10 CW buffers are 12 chars long, so the message is placed in buffers 1 and 2 if it is longer than 12 characters, and they are concatenated.

Page 89 Appendix D: Balanced Mic Usage The front panel 8-pin microphone connector can be used for balanced or unbalanced microphones using pins 7 and 8. If an unbalanced mic is used, pin 7 should be used for ground and the center pin, pin 8, used for the audio. If a balanced (XLR) mic is used, either pin can be connected to L or R. The ground pin, if used, should be connected to pin 5. A very good microphone to use with Sienna is the Heil PR-781. It has an XLR connector.
