FT2000 USB and LSB Alignment
My FT2000D has always been about 8 - 9hz off center frequency and one day, I will fix this. Now, 8hz is not a lot but for those with wideband audio setups to "hear" ESSB received audio, the beat notes produced by this amount of offset can be clearly heard. And this clue is what led to this procedure.

No external equipment is needed which makes this a very handy technique to use. Please ensure the radio is been on for at least 30 mins before making this adjustment.

To check the radio's alignment, press the "10" button, then adjust the VFOs to display "10.000.00" in both display panels. Select "USB" for VFO A and "LSB" for VFO B by pressing the "A<>B" button repetitively.

Next push the "RX" for VFO B and you should see a "BUSY" displayed in both VFO panels. Adjust the volume level for each VFO so that both are heard clearly.

If both sidebands are zero-beat, you'll hear a solid non-warbling tone after the 1 min time announcement. However, for most radios, you will hear warbling beat note formed by the difference in frequency between the two sideband frequency adjustment. It will be clearly audible.
Press "MENU" button and rotate VFO A to select "043GEnE". The display should show "0" since this value represents the factory default setting. The range of this adjustment is -25 > 0 < +25.

Rotate the VFO B knob until the beat note is reduced to zero. To do this for my FT2000D, it takes a setting of "8" [meaning 8hz) to remove the beat note. Now both USB and LSB are at the same offset so that for Rx or Tx, the SSB audio will sound the same for a "calibrated" rcvr. Note that many rcvrs are NOT so you need to be careful in evaluating this.
FT2000 USB and LSB Alternate Method
Another method to correct USB/LSB freq offset is to follow the procedure detailed above to find out how much freq offset correction is required. Then use the following method to correct the freq offset.

No external equipment is needed which makes this a very handy technique to use. Please ensure the radio is been on for at least 30 mins before making this adjustment.

Download the "FT2000 Complete Alignment Manual" here and follow the instructions [HOW TO ACCESS THE HIDDEN/SERVICE MENU] to place the FT2000 into the "alignment" mode.

Then select the "A15" item called "FrE" that controls the setting of the 2nd LO freq adjustment. Add the required correction to the current setting (factory default for my FT2000 = "159") to arrive at the new setting of "163". Store the new setting and then go back and execute the above procedure to see how close you are. Note: set "#043" back to the factory default setting of "0".

Item#   Name    Desc         CLAR      VFO-B    VRF   New

This procedure was developed while assisting W5MIX, Matt with his FT2000 alignment.
