Well,
thanks to the wonderful people at LDG, my CPU for the tuner is on
the way back to them to get a physical, or is that a
psychological? evaluation. I am very much hoping I got one of the
only bad chips made :-)
Reading the alignment instructions, said you can do it power off..
so figured I can check the rest of the circuitry. Mounted
everything back up, tested all the LEDs and started on the
alignemnt. after a minute realized I had my power meter on QRP
setting, so was using 1 watt, not 10 watts. Went back and zeroed
the cap (took a whole 22.345 seconds or so). then I did the rest
of the alignement. Found that the two resistors were almost
right on the money in the center position. Had to be very gentle
with the adjustment.. seemed pretty sensitive.. hard to get it to
measuer 4.5 volts and not 4.51 or so. I believe I settled for
getting it within about 2 hundredths. But the alignment went very
smoothly. I take it to mean that there is a good chance all that
circuitry is ok. I also know the tune button got the thing a
spinning and the auto/manual switch seemed to make a difference. I
am praying it was just the chip, so I can just plug in the
replacement and have a working auto-tuner.
This is one of my most wanted accessories for quite some time.
