OT: MLA 30+ loop test. On a lark, picked up one of these disposable loops for the occasional visit to the higher bands which my log is too large for. Seen all the reviews, which vary in content. Not interested in modifying because if I do that, I'll just get a W6LVP. Too much gain! Initially attenuated the output, but that didn't change the crappy s/n, just overall level. Got in the ballpark of usability by making sure my rig's preamp and attenuators weren't on. It took about a quarter-turn clockwise of the mla30+ preamp's gain pot to just tickle the s-meter at S1. NOW it is under control. Guess my overall noise level is pretty high, but no need to make it higher than about S1 with no activity. Otherwise it was just a noisy smoke-show which I almost tossed in anger. USB cable: I do use a portable battery with it, but the supplied usb cable presents what looks like an initial short when connecting. The Anker portable batts just turn off immediately. Tossed the oem cable, and used a Samsung phone cable. Tada, batt stays energized. The Anker batts seem ok with the little current drawn - whereas some other batts will time out quickly if not drawing more than 100ma current. Looks like the Anker's operate at 50ma minimum. Switching noise? From 160 to 10m, I'm not hearing the switching. Maybe down in BCB to VLF, but I'm not listening there. The funky frequency-vs-gain thing is there, but not a showstopper. Adjusting /reducing the internal gain pot to S1 on 30 meters seems to be ballpark. And now rotation actually seems effective. No common-mode seems to be evident, but as a precation, I did wrap the feedline with a few turns inside a ferrite a few feet away from the loop. Now if only 15 - 10m would open up more!
