I've been using the MFJ-949D that I picked up at a hamfest at a good price. For the money it seems to be a good entry-level balanced-line. But it is VERY touchy to tune--just like my MFJ loop tuner box. If it exists, I'd really like an auto-tuner to run balanced line. QRO-capable would be great too. So far I've checked LDG, MFJ, Ameritron, and Palstar--but I may have missed something. Unless I stay with a manual one, so far no luck. Only thing I can see that sort of fits the bill is a remote tuner, something like the RT-600 or SCG-230. But given the months of rain on end, and the tendency of my kids messing with antenna stuff in the yard, I'd rather not go that route. Am I looking for something that doesn't exist? Only other option is trying to hookup the MFJ legal limit tuner to a coax stub to a balun, etc. I've not had luck with that, but maybe I did something wrong. This question seems to come up every few years but never gets resolved. I suspect there isn't a auto-tuning balanced-line one, but maybe something has changed, or maybe there was one a few years back but isn't on the market now, etc.
