LDG Z-11 Pro
To go with my new Yaesu FT-857D an antenna tuning unit (ATU) was also thought to be a good investment. My first choice (an MFJ) was out of stock, so on recommendation it was replaced with the LDG Z-11 Pro
I though this might have been tricky to use, but it really is straight forward. Keying CW on the required frequency at low power (5 or 10 w) results in the LDG searching for a good SWR. The relays can be heard clicking away, but then (hopefully) the only remaining LED Is the 1.5 indicating a SWR of that or less.
