Page 3: Introduction
The FT-891 is a rugged, innovative multiband, multimode mobile/portable transceiver for the amateur radio MF/HF/50 MHz bands. Providing coverage of the 160 - 6 meter bands, the FT-891 includes operation on the SSB, CW, AM and FM modes, yielding the most comprehensive performance package available for mobile and field operation. -

Page 6: Power Connection
Installation Power connection The DC power connector for the FT-891 must only be connected to a DC source providing 13.8 Volts DC (±15%), and capable of at least 25 Amperes of current. Always observe proper polarity when making DC connections: The Red DC power lead connects to the Positive (+) DC terminal;... -
Page 7: Grounding
RF grounding can nullify such filtering. Bonding the FT-891 transceiver to the vehicle or vessel’s ground system should clear up any such difficulties. -
Page 8: Base Station Earth Grounding
This so-called “Daisy Chain” grounding technique may nullify any attempt at effective radio frequency grounding. See the drawings below for examples of proper and improper ground connections.

Radio Relay League, Inc. (225 Main St., Newington CT 06111 or <http://www.arrl.org>). Although there is negligible radio frequency (RF) leakage from the FT-891 transceiver it- self, its antenna system should be located as far away from humans and animals as prac- ticable, so as to avoid the possibility of shock due to accidental contact with the antenna or excessive long-term exposure to RF energy. -

“Transmit Request” command on the ring connection. The main shaft is the ground return. The “TX Request” connection, when shorted to ground, puts the FT-891 into the trans- mit mode, and sends out a steady CW carrier, for linear amplifier or manual antenna tuner adjustment. - Page 13 DC IN Jack This is the DC power supply connection for the transceiver. Use the supplied DC cable to connect directly to a DC power supply, which must be capable of supplying at least 25 A @13.8 VDC. FT-891 Operating Manual...

VFO-A frequency. Four small numbers on the Display show the current Clarifier offset. The Clarifier controls on the FT-891 are designed to allow setting a preset offset (up to ±9.99 kHz) without actually re-tuning, and then to activate it via the Clarifier [ CLAR ] key. -
Page 18: Advanced Operation
If you disable the AGC by press and hold the [ B ]( AGC ) key, the S-meter (which monitors AGC voltage) will cease to function. Depending on the setting of the RF Gain control, incoming signals will probably be distorted if the AGC is turned off. FT-891 Operating Manual... -
