Just received a ZM-2 QRP antenna tuner of the Z-Match design that I ordered from Emtech. It seems able to match a random wire with ease on multiple bands. In the video below I threw about 10m of wire into a tree and was able to tune up on 20m, 40m and even 80m.
Tuning is quite sharp and for transmit there is a built-in SWR bridge with an LED indicator that you tune to extinguish.
It's a compact unit, a good companion for the FT-817, and works very well. Rated at 15W maximum it's perfect for QRP operation.
Mine took about a month to arrive here in Sydney and even came with handy hints on how to get into heaven!
