I was looking for a light weight tuner to pair with my TX-500 ( it arrived yesterday and works great!) and came across a Z-Match, the ZM-2 from Emtech, .
Further investigation gave it a good review for its frequency range but it did not cover the 160m band.
Looking more, a found that there is a ZM-4 available from , in Germany, that is very compact and it covers down to 160m.? It will match both symmetrical (low imp loops aand dipoles) and asymmetrical (end fed wires). I bought mine (ZM-4 ATU) as a kit but have not gotten time to build it yet. With shipping and currency coversion it is around $125 and about a month to get here to Wisconsin.
Size wise it is about the length from the left side of the TX-500 to the right edge of the display and about an inch longer than from the bottom of the tx-500 to the top and approx the same thickness. The? case is extruded aluminium and the parts mount on a nice circuit board so it appears it should be rugged.
Check out both if you want. I have no affliiation with either place but just wanted to make the new community aware of these. I am sure there are many other light weight designs too.
