If you did your test on Friday, I was also noticing that noise difference as compared to Thursday. We have been doing some testing but no adjustments at the repeater site. Bruce has been trying to tweak some software that's in the mix now. I haven't had a radio on today (Saturday), but I did finally get the sewing machine back into service after damaging gears about 6 months ago. I had the replacement parts on but was a learning curve to get the feed dogs, the needle and the takeup all aligned and timing. I had a copy of weeks ago almost together but stitches were being randomly dropped. The needle was bent, but I had tried to time with that bent needle. A new needle installed and then the timing needed readjusted. I am happy with myself. Now just need to find the proper grease as machine hadn't been serviced in years. It was xyl's hs graduation present from her parents. Only one extra part that was found when opened it up and today determined where that came from. Fortunately, in my opinion, that piece is not critical. It is probably stainless and was welded to stainless, microdot weld of about millimeter microdrop on bobbin slide. Yep, learned a whole bunch of new terms.
Great low power from your qth.
