Just picked up this tuner. Ordinarily I use auto-tuners such as the LDG line. I think they make very good products but in this case I needed a small non-auto tuner for use with my ARK-40. The ARK-40 does not have an adjustment to set the RF at anything less than its 7-watt output and matching an auto tuner with an MFJ SWR analyzer isn't going to happen with its 15 milliwatt input. As a result I picked up the MFJ 971. I usually avoid MFJ products like the plague. They have had over the years many quality control issues. I took the tuner lid off to set the jumpers for Qrp operation and noted that everything was as it should be with no cold solder joints etc. It turns out that the tuner works quite well with ARK-40. In fact I just had an 8 AM qso with a Philadelphia ham, Jerry, whose call sign is one for the books: N3HAM!
73 for now, Mark.
