National NC-125
#10

I am pretty tired today. Playing with the NC-125 last night I noticed that the 1.5 MC to 4.5 MC band was off. CHU Canada, which should have been at 3.33 MC was at 4.2 MC, so... back to the bench it went about 1 in the morning. After a great deal of fiddling around, I got the band properly aligned. Having played with this radio for a while now, the manual makes more sense, but it does take some playing and figuring things out. I finished about 4 in the morning, and re-tested the radio. That band now works REALLY well. I got CHU right where it should be, louder and clearer than before. I also got WWV at 2.5 MC, which is difficult because of the power lines over my pasture. I am very pleased, but I think I am going to do a little more tonight. I am going to leave the radio where it is, hooked to my main antenna. All the bands are properly aligned as to frequency, but I think I may be able to tweak the RF amps just a hair more on the other bands than the one I did last night. It will be pretty easy though. There is a little plate on the bottom cover which is held by 2 screws, and under it I can access the proper variable trimmer condensers. Anyway, I finally went to bed at 6 AM, and my dogs woke me at 8 AM. needless to say I am pretty tired. I may take a nap in a little while.
