First look to the service manual and adjust a propper bias current for the final PA stage !!

FT-2000 Comprehensive EQ Settings

Posted by: "John Occhipinti"

Congratulations to the new FT-2000 users who are requesting a quick setup for optimum performance on SSB.
These are the initial basic settings used for ESSB (Enhanced Audio), for those who want broadcast quality emanating from their FT-2000.

REVISED SETTINGS: January 1, 2007
Here are my REGULAR MENU settings for the FT-2000.
Menu 083 at 3000 (Wide Band Setting)
Menu 123 at 100 (Low Freq.)
Menu 126 at 1500 (Mid Freq.)
Menu 129 at 3200 (High Freq.)
Menu 124 at 5
Menu 125 at 5
Menu 127 at 4
Menu 128 at 3
Menu 130 at 3
Menu 131 at 1

Here are the separate settings when using the Parametric Microphone Equalizer. These settings are engaged when using the Speech Processor in the FT-2000 .
Note: With any outboard EQ audio gear, this is not recommended. I never use the speech processor in the radio, because I always use outboard audio gear.

Menu 132 at 100
Menu 133 at 5
Menu 134 at 5
Menu 135 at 1500
Menu 136 at 5
Menu 137 at 3
Menu 138 at 3200
Menu 139 at 5
Menu 140 at 1

Here is a quick setup for the FT-2000:
Put mic (audio) into #15 in rear using an RCA plug. Then Menu 082 is set on "front"
(this enables you to achieve 50 hz to 3.5 kHz on transmit).
Put the WIDTH control all the way to the right (clockwise) and put the SHIFT in the center. The WIDTH meter will have all the green LED's lit and this enables you to receive out to 4 kHz.
Menu 061 Change it from "ofset" to "dir" (this is to keep the Frequency readout the same when you change from USB to LSB).
Menu 144 Change from "diS" to "EnA" ( this enables you to use the LINEAR AMP)!
Linear RCA plug goes into #20 in rear.
Record mini plug goes into #22 in rear (AF OUT).
Power Master Watt/SWR Meter: 13.8 vdc goes into #21 in the rear.
These are the most important settings to start with.

If using the Behringer Ultra Curve 2496, these are the basic settings:
Use 60 hZ at +15, 80 hZ at -10, 100 hZ at -10, 160 hZ at -15, 315 hZ at -10,
400 hZ at -10, 500 hZ at -10, 800 hZ at -5, 1K at +10, 1.6K at +10, 3.2K at +12. You can put all the Bandwidths at 1.

If using the W2IHY 8 Band EQ and the EQ Plus, these are the basic settings:
8 Band EQ:
50 +12
100 +6
200 0
400 -4
800 -16
1600 +6
2400 +10
3200 +12

EQ Plus:
Bass 3 o'clock
Treble 2 o'clock
Compressor 12 o'clock
DE Level 2 o'clock
Impedence 200 (down position)
Effects:
Delay Fully Counterclockwise
Effects Level 10 o'clock
Effects Switch Up

Use good headphones and monitor yourself. As you can see, I do use the internal EQ on the FT-2000 but I do NOT use the Processor. Contact me for an "on the air" QSO, recording and graphing of your audio and I will email you both the mp3 recording and the SpectraPlus graph of your audio. Thank you.
73's,

Heil Handy Mike with HC5 element direktly to the FT 2000 mike plug

HC5 Element

    HC-5 Specifications:
 Type: - Dynamic. Copper wound bobbin, moving coil transducer
 Frequency: 350 Hz to 4,000 Hz with 6 dB rise at 2,000 Hz.
 Sensitivity: -68 dB Nominal
 
Impedance: 2,000 ohms @ 1,000 Hz.
 


The result is an SSB signal of remarkable clarity, without a "pinched" or "bassy" response, and no microphone amplifier power is wasted in the amplification of unnecessary low-frequency audio. The mid-range response is very clean and natural-sounding; operators will stop you in the middle of a QSO and ask you what microphone you are using to achieve that great audio!
