50.[TUNER] Button

This is the on/off switch for the MARK-V FT- 1000MP’s Automatic Antenna Tuner.

Pressing this button momentarily places the antenna tuner in line between the transmitter final amplifier and the main antenna jack. Reception is not affected.

Pressing and holding this button for ½ second while receiving in an amateur band activates the transmitter for a few seconds while the automatic antenna tuner rematches the antenna system impedance for mini- mum SWR. The resulting settings are automatically stored in one of the antenna tuner’s 39 memories, for instant automatic recall later when the receiver is tuned near the same frequency.

51.VRF Indicator

This indicator glows red when the VRF feature is activated by pressing the [VRF] button on the Shuttle

52. VRF/MEM CH Knob

When the VRF feature is engaged, use this detended knob to tune the passband of the narrow in- put preselector filter manually for maximum receiver sensitivity (and out-of-band interference rejection).

At other times (when the VRF feature is “off”), this knob selects the operating memory channel when the memories are active (but not retuned). When the VFO or memory tune functions of the main display are ac- tive, turning this knob causes the Sub VFO display to temporarily show the frequencies of the memories (memory check), without otherwise affecting operation. The channel number of the selected memory is dis- played at all times at the center right of the display (in front of “CH”).

Pressing and holding this knob for ½ second en- ables the “VFO Step” feature, which allows “channellizing” the VFO for quick frequency navigation. Menu Selection 1-5sets the VFO Channel step size.
