• IF Shift -For reduction of adjacent-frequency interference.
• IF Noise Blanker - For reduction of ignition and other impulse-type noise.
• IPO (Intercept Point Optimization)-
Bypasses RX Preamp on HF/50 MHz for
improved performance during strong-
signal conditions.
• ATT (Front End Attenuator) - For more pleasant reception of very strong signals.

An optional filter slot is provided in the FT-817, allowing the owner to install one of two available ten-pole Collins (R) Mechanical Filters. For CW operation, choose the YF-122C (500 Hz bandwidth), or for very natural-sounding SSB select the YF-122S (2.3 kHz bandwidth).

The power of microprocessor control brings you mode-selectable tuning steps as fine as 10 Hz for the Main Dial (SSB/CW), and quick-tuning steps of 1/2.5/5 kHz using the SELECT knob. Via Menu, you can disable the Main Dial on AM and FM, for even-frequency navigation, or the Main Dial may be activated for tuning in 100 Hz steps. Pressing the microphone's [FST] key doubles the SELECT knob tuning rate, and multiplies the Main Dial's tuning rate by a factor of 10. And if you press the SELECT knob first, you can fly across the band in 1 MHz steps!

For quick and efficient access to the many high-performance features of the FT-817, the SELECT knob teams up with the [A] [B] [C] keys to provide a "miniature front panel" for ease of operation. There also is a convenient "Menu" mode, providing customization of a number of "set and forget" operating functions.

Enjoy shortwave and FM broadcasts, public safety communications, and airband calls thanks to the extended frequency coverage of the FT-817, which includes reception on 100 kHz~ 56 MHz, 76 ~ 108 MHz (W-FM only), 108 ~ 154 MHz, and 420 ~ 470 MHz!

The front panel includes a convenient BNC connector for attachment of a whip or VHF/UHF rubber flex antenna (supplied). The rear panel includes a type "M" ("SO-239") connector. As shipped from the factory, the BNC jack is active on 50/144/430 MHz, while the "M" connector is active on HF.

The Menu system allows you to define which connector will be selected for HF, 50 MHz, 144 MHz, and 430 MHz, so if your VHF Yagi's feedline uses a PL-259 connector, just use the Menu to select the "Rear" connector on 144 MHz!

A wealth of information is available on the front panel:

• When you have to be away from the radio for a few minutes, but would like a visual indication of activity while you're away, activate the Spectrum Scope Monitor. The Spectrum Scope Monitor allows you to watch activity ±5 channels from the current operating frequency.
• The LCD illumination color may be set to either Blue or Amber color, using
the Menu.
• Watch for low battery trouble using the Battery Voltage Meter display selection.
• For ease of viewing while outdoors, you can double the size of the frequency display.

• Split-frequency operation using
VFO-A and VFO-B for DX pileups.
• SSB TX and RX adjustment of carrier insertion point, for customization of audio response. • RF GAIN control.
• AGC FAST/SLOW/AUTO selection.
• VOX T/R control. • Modulation and SWR indication on LCD. • ±9.99 kHz Clarifier (R.I.T.).

CW PORTABLE OPERATION
HAS NEVER BEEN BETTER!

• CW "Semi Break-in," with T/R recovery delay programmable from
10 ms ~ 2500 ms. At 10 ms setting, performance emulates QSK operation.
•CW Reverse: provides BFO injection from LSB-side, instead of default USB-side.
• CW Pitch Control: adjusts TX offset and (identical) sidetone between 300 Hz and 1000 Hz in 50 Hz steps; this allows precise spotting on DX stations. Sidetone level is adjustable.
• Built-in Electronic Keyer, with speed adjustable between 4 WPM and 60 WPM, and Weight (Dot:Dash Ratio) adjustable between 1:2.5 and 1:4.5.
•For emergency use, the Menu allows you to set up the Microphone's [UP] and [DWN] keys for generation of "Dots" and "Dashes" on CW!

LEADING-EDGE FEATURES THAT GET YOUR MESSAGE ACROSS!

Despite its compact size, the FT-817 sports an impressive array of Memory features. You get 200 "regular" memories which store frequency and mode information, and each memory may have an 8-character Alphanumeric "Tag" (label) appended for quick channel identification. What's more you get four HOME Channels (one each for HF/50/144/430), a pair of Band-Limit "PMS" memories (M-PL/M-PU), a one-touch "Quick Memory" channel for a favorite operating frequency, and (for U.S. customers) access to the "Alaska Emergency Channel" (5167.5 kHz), for a grand Memory Channel total of 208 channels! Ten Memory Groups are available (holding up to 20 channels each), allowing you to organize the 200 Memory Channels efficiently.

• VFO Scan: Allows you to scan the band, looking for activity. If a signal is heard, the scanner will pause, resuming according to the preferred method you set via Menu.
• Memory Scan: Scan all the memories, or just those in a Memory Group. You can also define certain channels (such as beacons) to be "skipped" during scanning, if you like.
• Programmable Memory Scan (PMS): A special pair of memories may be used to set up band scanning limits (so as to limit 144 MHz scanning to the "FM" portion of the band, for example).
• Dual Watch: Lets you operate on one VFO, while checking the other VFO every five seconds, looking for activity.
• Priority Channel: lets you operate on a Memory Channel while checking Memory Channel 001 every five seconds.
• Smart Search: Provides automatic loading of up to 50 AM/FM frequencies, based on an activity search of the current band. Perfect when visiting a new city on a business trip!

• 50 CTCSS Tones are available for use
in either an Encode-only or Encode-Decode mode, along with 104 DCS Encode/Decode control codes. CTCSS and DCS information may be stored independently on each Memory Channel. If you don't know the other station's tone or digital code, use the handy Tone Search or Code Search features to track down the tone or code automatically!
• For Search-and-Rescue operations, the Auto-Range Transponder System (ARTS™) utilizes the FM DCS code system in a polling mode, allowing the base and portable station to know when an "out of range" condition exists. The portable station then knows to move to a better location in order to re-establish communications.

• For 1200 or 9600 bps VHF/UHF Packet work, a convenient industry-standard mini-DIN connector is provided, making interfacing quick and efficient. Easy connections are also provided for SSB-based Digital modes, and the Menu includes custom setups for RTTY, PSK31 (USB and LSB both supported), and two user-defined modes (for SSTV, etc.). The optional 500 Hz CW filter may be utilized during narrow-band Digital operation.
