Transmitter Bandwidth Settings for eSSB

The following chart is a reference for those who need to set up their transmitter audio bandwidth to accomidate eSSB (Extended Single Sideband) for high-fidelity transmissions, or to at least give the transmitter a chance to sound the best it can.

Menu #25 Mic Gain 85
Menu #16 Mic EQ 3
Menu #64 XMT Carrier shift -.05 to +.05
Menu #65 SMT Carrier shift +.05 to -.05
Menu #27 Compressor level 80
64 and 65 carrier point is very important

Power on the radio while pressing

If you are using original firmware:
Go to menu item 083 (SSB TX BPF)
To download newest firmware, click here.

If you are using the new firmware update:
Go to menu 085 (SSB TX BPF)

Where you used to find 3000WB, you will now find TTBF (4 kHz bandwidth ESSB mode) .

Push "MENU" button in and listen for beep to save the settings.

The FT-2000/FT2000D is now in the 50 Hz to 4 KHz transmit bandwidth.

To receive 4 kHz, put the "WIDTH" knob fully clockwise; You will see all of the LED's lit. Put the SHIFT knob in the center. You will see these changes on your DMU.

There is a secret "Power On" function built into the FTDX-5000 & FTDX101D/MP that allows the rig to transmit from 50Hz to 4kHz. It is called TTBF which stands for Total Transmit Bandwidth Frequency. Once enabled, it will extend your transmit bandwidth right out to 4kHz. You may need to re-EQ your mic to tailor it to this new bandwidth.

To enable TTBF, turn the radio ON while holding in DNF on the CENTER VFO-A and DNR on the FAR RIGHT VFO-B.

Note: The DNF and DNR are right next to each other in between these 2 Sub VFO's. Once done, push the MENU button and turn the CENTER Sub VFO-A to MENU 104 A3J. Next, turn the FAR RIGHT Sub VFO-B fully clockwise and TTBF will appear. If you did this Power On mod correctly, should see TTBF instead of 3000WB. If you still see 3000WB, that means your little Power ON "mod" is not done right. Ya gotta do it again.

Pprogram your CS button to take you directly to this menu so that if I need to change the TX bandwidth on a fly, I just hit the CS button and it'll prompt me right to it and change the BW quickly. This is one of the neatest feature of this rig since sliced bread :)

Note: The WIDTH control on the rig is the receiver's bandwith adjustment. For hi-fidelity audio reception, turn this knob fully clockwise. This is the one and only knob out of the whole rig that is turned "All The Way To The Right!" :) You'll see that the display will show WIDTH 4.00kHz and the receiver will open up nicely.

TTBF Settings for eSSB: (4kHz BW)
1) Turn off the 9000 via front panel switch.
2) Hold the "AFL" and "ACM" buttons in while turning the power on.
3) Under menu "No. 070", the TTBF should now be ON. You're done!
4) To reverse the process, just repeat the process.

If you have a 6 kHz filter installed,
you can use WIDTH to select a wider passband.

In CONFIG:TX eSSB, change the parameter
from OFF to one of the provided selections
(3.5, 4.0, etc.).

With eSSB enabled, the transmit EQ menu entry name changes to MAIN:TX*EQ to allow you to independently adjust EQ at the selected wider bandwidth. The amount of adjustment required at each EQ band may vary depending on the selected eSSB transmit bandwidth. (See manual pg 36)
