• 2.4KHz 4-pole Inrad crystal filter at the 9MHz 2nd IF (upgradeable to 10-pole 2.4kHz, or 8-pole 2.8kHz)

• 20KHz ceramic filter at the 455KHz 3rd IF (plus two more in the FM detector) and a wide selection of optional Inrad and Collins filters (4 for each IF total) ranging from 5.8KHz to 125 Hz, accessible by removal of a bottom cover plate

• 20kHz 4-pole crystal roofing filter at the 70.000MHz 1st IF (upgradeable to 4.5kHz @70.455MHzversion for better close-in BDR)

• Two 10dB RF preamps, one 10dB attenuator and PassiveSignalBoost^TM (bypasses bandpass filters in the front end for reduced loss, to really pull in the weak ones)

• +/-1ppm TCXO (30MHz) with 10-turn pot adjustment

• 455KHz broadband IF output drives many spectrum analyzers, even the venerable Heathkit SB-620!

• Built-in calibration reference - Transmitter BFO can be fed into main antenna iuput with cal/rcv switch in "cal" position, which inserts an attenuator in the line such that a 50uV signal is fed into the receiver for calibration of the S-meter

• Gas discharge protected A/B/Rx antenna inputs

• Noise blanker with three pulse widths and variable threshold

• Separate headphone and speaker amplifiers, both active simultaneously with separate volume controls

• "Hang"-type AGC - IF derived attack, audio-derived decay with excellent response (Off, fast, slow, auto settings)

• AGC gain settable from menu, with separate calibration controls for preamp1 & preamp2 to allow S9 signal to read S9 no matter which preamp is engaged

• Separate AGC gain cal setting for AM mode, settable from menu

• Keyer (manual and paddle inputs active simultaneously) with front panel or remote control of sidetone volume, pitch, speed, dot weight and dash weight, plus CW Spot and CW PTT. Iambic A, Iambic B and Ultimatic modes supported (available even on receiver-only models so you can work on your code practice!)

• 147 total memories: 85 user-changeable non-volatile memories (10 per major band, 5 per WARC band, 5 60M channels, 5 general purpose) preset to the ARRL bandplan (European, Asian, military and government bands also downloadable), plus one scratchpad memory which always wakes up on WWV. Memories accessible via optional external keypad or PC.  Five VFO-A memories per band, on each of 10 bands. One VFO-B memory. Each VFO memory maintains frequency, mode, filter and tuner settings. 10 12-character CW memories

• Scan from any memory (in 85-memory group) to any other memory OR from VFOA to VFOB in programmable frequency steps, with 5 programmable S-meter trigger levels and dwell times

• Split mode operation - cross-band, cross-mode (VFO A and B can have different frequency, mode, filter and tuner settings)

• RIT/XIT controls have +/-16MHz range with no degradation of transmitter or receiver performance. If you're not changing mode, this can be a handy way to do cross-band split without having to go into split mode.

• Support for Yaesu FH-1, FH-2 or similar external 12-button keypad included, with Memory/Split mode, direct band entry and CW message buffer activation without changing modes in a menu

• RS-232C interface, command set compatible with Kenwood TS-570, works with any remote control software  -- run common  remote control programs right on the rig!

• Over-voltage, under-voltage, over-current, reverse polarity protection

• Anderson Powerpole DC input connectors with included pre-wired adapter for a power supply

• Room to insert a battery (sealed lead-acid batteries available at Batteries Plus) or 100W amplifier inside

• Room to add an internal embedded PC (see options below)

• Thermistor-controlled fan

• Firmware upgradeable via download from web (and if you have the optional internal PC, it can be done directly from the rig, with the LAN port connected to the web!)

• Superior industrial design - good-looking, rugged compartmentalized aluminum and steel chassis with captive fasteners, polycarbonate multi-color front panel, high quality parts, and on front panel models, a heavy machined aluminum tuning knob with thumb indent, backlit analog meter(s), uncluttered control layout

• Front Panel kit ($499 U.S. List)
  

  • Analog backlit meters, one for receive, one for transmit functions

  • Handsome blue-green vacuum fluorescent graphics display (Noritake 256x64)

  • Single level menu system with simple, intuitive controls and text legends

  • Mic jack (8-pin Yaesu pinout)

  • Headphone jack with separate volume control from speaker

  • Manual and paddle key inputs

  • Lighted pushbuttons with positive, non-"squishy" feel

  • Two velvet-smooth rotary pulse generators for main and auxiliary tuning

  • Front Panel PC board, steel panel, polycarbonate overlay and all discrete parts, goes together quickly

  • Add to any Sienna model at any time
     

• 70.455MHz 4.5kHz roofing filter ($125 U.S. List)
  For enhanced receiver performance on CW and SSB (A highly recommended option!)
  
  
   

• 10W all-mode transmitter kit ($399 U.S. List)

  
  This 10W transmitter board is pre-loaded with SMT parts. You add all the through-hole parts, such as transistors, connectors, crystals, transformers, toroids and power transistors (which you also attach to the heatsink that is mounted to the back).

  • RF speech processor

  • variable BW (1.0-2.4kHz) 7th-order Chebyshev crystal filter for SSB

  • fixed 6kHz 7th-order Chebyshev crystal filter for AM/ESSB

  • 1mW transverter output

  • Full metering of SWR, forward and reflected power, PA voltage and current, ALC and compression

  • full-duplex operation (transmitter runs independently of receiver)

  • CW spot function disables transmitter and allows you to adjust the pitch control to match the signal being received, or to use keyer for code practice without touching the RF power control

  • fast, silent QSK with programmable delay (min 3ms)

  • CW PTT function available via menu option [PTT signal required before key is recognized]; PTT input available on Mic connector and RS-232 DTR line, with RTS available as a keying input. Also, full break-in delay can be set as low as 3ms, and full duplex mode keeps receiver on even during transmit (transmit signal feeds through if you are listening on your transmit frequency)

  • external amplifier I/O: band, txgnd, alc (0 to -5V), +12V@200mA, tx enable

  • Tx disabled outside amateur bands, AND when operating outside your license privileges "Out of band!" error message in display lets you know when you've tried to transmit on a frequency outside your license limits. (Select your license class in a menu item). Band limits for various countries, MARS, CAP, military, government, etc., will be downloadable from our web site. Proof of license required to download alternate transmitter limits.
     

• 100W amplifier kit ($349.00 U.S. List )
  Includes two-speed thermistor-controlled fan outputs. 100W CW, 100W PEP SSB, 25W carrier power on AM and FM. Requires transmitter option.
  
  
   

• Antenna Tuner kit ($169.00 U.S. List)
  The internal tuner kit consists of 7 toroids, 7 silver mica capacitors, Polythermaleze magnet wire and 14 high current relays which you mount on an existing board within the unit. A switched-L-style matching network tunes 6-800 ohm unbalanced antenna impedances via the antenna A/B SO-239 antenna connectors at full rated power. Not intended to match long-wire antennas without baluns. Internal memory stores 200 tuner settings including antenna A/B. Retunes automatically every 32kHz. Memory recall is instantaneous. Tuning time for worst case match is 54 seconds. Typical match occurs in <3 seconds. 8A relays can take a lot of punishment, but power is automatically limited to 10W during tune. Existing L/C settings visible in menu. Forced retune on previously tuned band segment also selectable.
  
   

• Internal fanless PC ($599.00 U.S. List)
  600MHz Celeron, 8G CF running Windows with SiliconPixels ChromaDSP software (also can run Linux, but no additional software is bundled)
