I have an MFJ random wire tuner which I like. What I've done with various antennas is to create a table of settings that I can return to as needed. It's a simple unbalanced L network.?
? ?I have considered the notion of a hybrid tuner. The idea would be that the settings for various frequencies would be repeatable. Hardly any setup requires ALL possible tuning solutions, especially with a single antenna. So why not just build or modify a tuner with settings for the frequencies that I use? The number of components could be vastly reduced to only certain L and C values. The settings could even be achieved with relays activated by the bands or frequencies you're on. I truly don't know if there's a way to externally track frequencies, but I do know that the chosen band information is available on the 817 rear panel. Other radios too I suppose. Settings in the correct band may be all that's required though depending on antenna bandwidth at frequencies of interest.
? ?Just a thought.?

Finally getting back on this, regarding a new MFJ-9219 manual tuner that was not working for me.
I returned the original unit, and they sent me out a new one.? This seems to be working fine.
I was able to get excellent to acceptable SWR on all bands from 10-160 meters.
My plan is to review it on eHam, as I see nobody has done that yet.? I like the size and functionality.? I have to remember, however, to tune for each band, each time.? This was not an issue with the LDG Z817.
Assuming it lasts, I think I would recommend it for its small form factor and multiple functions.
