FT818ND portable transceiver for the amateur radio

The FT-818 is a compact, innovative multiband, multimode portable transceiver for the amateur radio MF/HF/VHF/UHF bands. Providing coverage of the 160-10 meter bands plus the 6 m, 2 m, and 70 cm bands, the FT-818 includes operation on the SSB, CW, AM, FM, and Digital modes, yielding the most comprehensive performance package available for portable operation.

Designed for use either from an external DC power source or internal batteries, the FT-818 provides 6 watts of power output from a 13.8-Volt external power supply. When using the SBR-32MH Ni-MH Battery Pack or 8 “AA” Alkaline Cells (not supplied), the FT-818 automatically switches to 2.5 Watts of output power.

The multi-function Liquid-Crystal Display includes Blue, Amber, and Violet backlighting, which may be disabled for battery conservation. The display includes bar-graph indication of power output, ALC voltage, SWR, and modulation level. Also include are a number of operating status icons, as well as the function displays for the three operating function keys ( A, B, and C ).

  1. PWR Switch

Press and hold in the PWR switch for one second to turn to the transceiver on or off.

  1. AF Knob

The (inner) ( AF ) knob adjusts the receiver audio volume level presented to the inter-
nal or external speaker. Clockwise rotation increases the volume level.

  1. SQL/RF Knob

In the USA version, this (outer) (SQL/RF) knob adjusts the gain of the receiver’s RF
and IF stages. Using Menu Selection 45, this control may be changed to function as
a Squelch control, which may be used to silence background noise when no signal is
present. In the other versions, its default setting is set to “Squelch”.

  1. lock Key

Pressing this key locks the front panel keys so as to prevent accidental frequency

  1. V/M Key

Pressing this key switches frequency control between the VFO and Memory Systems.

  1. TRANSMIT/BUSY Indicator

This LED glows green when the squelch opens, and turns red during transmit.

  1. MAIN Dial

This is the main tuning dial for the transceiver. It is used both for frequency tuning as
well as “Menu” setting in the transceiver.

  1. F Key

Pressing this key momentarily changes the display to show the operating functions
available via the A, B, C keys.

Press and hold this key for one second to activate the “Menu” mode.

  1. FUNC Keys

These three keys select many of the most important operating features of the trans-
ceiver. When pressing the F key, the current function of that key appears above each
of the A, B, C keys (along the bottom of the LCD); rotating the (SEL) knob scrolls the display through eleven rows of functions available for use via the A, B, C keys.


Pressing either of these keys momentarily will cause the frequency to be moved up or down by one frequency band. The selections available are:

1.8 MHz↔3.5 MHz↔5.0 MHz↔7.0 MHz↔10 MHz↔14 MHz↔15 MHz↔18 MHz

430 MHz↔144 MHz↔108 MHz↔88 MHz↔50 MHz↔28 MHz↔24 MHz↔21 MHz

  1. MODEM) < MODE > Key

Pressing either of these keys momentarily will change the operating mode. The selections available are:

  1. HOME Key

Pressing this key momentarily recalls a favorite “Home” frequency memory.

  1. SEL Knob

This detented rotary switch is used for tuning, memory selection, and function selection for the A, B, C  keys of the transceiver.

  1. CLAR Key

Press this key momentarily to activate the Receiver Clarifier feature. When this feature is activated, the (SEL) knob may be used to set a tuning offset of up to ±9.99 kHz. The transmitter’s frequency is not affected by the setting of the Clarifier.

Press and hold this key for 1/2 second to activate the IF Shift feature, which allows you to use the (SEL) knob to adjust the center frequency of the IF filter’s passband response.

  1. ANT Jack

Connect the supplied 50/144/430 MHz rubber flex antenna (or another antenna presenting a 50Ω impedance) to this BNC connector. In its default setting, this jack does not function on the HF bands. If you want to enable
this jack on the HF bands, recall and change the setting of Menu #07.
