It is not my normal policy to provide detail information that is available
in the service manual. However due to the nature of the note in the owners
manual for the FT-1000MP about not touching the VR6812 pot, and yet how easy
it is to accidently change it while making other acceptable adjustments, I
have relented and will provide the calibration information as it relates to
The following adjustment information comes from the FT-1000MP service
manual. This manual is a seperate purschase from Yaesu. On page 3-11 of the
service manual the location of the mysterious do not touch VR6812 pot is
ided as a Tuning Meter Center Preset. This same page has calibration
information for the Tuning Meter for CW, RTTY and PKT mode. The DC voltmeter
is specified as a "Digital DC Voltmeter (high-Z, 1Mohm/v).Alignment
Preparation at the begining of the service manual it says:
Except where specified otherwiise, the transeiver should be tuned to 14.2000
MHz, USB mode, and these controls set as indicated:
* MOX, VOX, AGC, PROC, IPO, ATT OFF
* MIC & RF PWR fully CCW (minimum)
* AR as required
* SQL fully CCW (minimum)
* NOTCH & SHIFT to 12-o'clock
Please read fully before performing. Not responsible for adverse affects, or
lack of results. I have put the word (reconcider) next to items that you
should leave as it is even though 'at This Point In The Manual' that is the
direction given. I am not sure if later in the service manual these
designated items are adjusted different from the presets given. Because
these items did not appear as adjustments to make following the preset
operations, I would suggest leaving them to the factory settings unless you
know what you are doing. Most of them are common sense and/or user
preferable settings. The next page in the manual goes onto Main Receiver

The owners manual has information for setting up the tuning meter for other
frequencies used in the digital modes, as well as some of the other
adjustments that you would be expected to adjust from time to time.
Note: I am not responsible for any errors from the manual, or any typos in
With out doing further research in to the owners manual ( which I dont plan
on doing at this time), this is all the information available in this
section of the service manual about the above items.
......and before you say it, yes I agree this information should have been
provided in the owners manual due to the function of the pot we are supposed
to leave alone, and the impact on the digital mode indications. It is also
one of the many reasons why I purchased the service manual........ hi hi
