The problem:
on my FT-1000D, the green LED "CW TUNE" on the display, flash also with normal noise, and in the earphone you can hear unwanted QRM caused by this ( when you turn the volume knob to minimum, this QRM still remain and you can listen him).
Solution:
Unfortunately, there is no trimmer, no regulations of the level of the circuit Q3044-Q3045 led driver. Very fast solution is to disable this circuit, simply turning to the OFF position all the first 4 dip-switches in the top of the radio, named "CW-PITCH". Effectively, only the last two work on the BFO, the first 4 only serves to determine the frequency at which the led flashes.
For example, to pitch at 600Hz without QRM of the CW-TUNE led, only the dip n. 6 go to the ON position.
Obviously, the led CW-TUNE circuit lose his functionality, the led never goes ON, but the QRM disappear.
