Retuning for a memorized frequency takes about 1. AT installation is simple. After some dramas rigging up an antenna mainly a height issuethe unit appears to work well. Usually closer to 2.

When tuning the same frequency twice, it is all over in less than a second. The manual says words to the effect of “Voltage input to trigger the start of the tuning cycle.

One drawback to using the AT with the is that every time I would change bands or frequency ranges the tuner would automatically tune. For example, the AT will match a 7 m 23 feet long wire antenna across the marine band in the 1. Normally 8 Volts, when less than 1 volt is recieved a tune cycle will commence”.

It is a capable tuner if you observe the following measures: I’m limited as to the amount of RF i can put through it but watts is OK for me and as i said i have a balanced antenna i just connect the open wire feeder directly to the atu, one leg of the feeder to the hot side and the other to the ground, and a common mode choke at the feed point between atu and transceiver.

The AT is housed in a durable, completely weather-resistant acrylic case with rubber gaskets. This line needs to be connected to your radio in a way that causes it to go into the transmit mode, and produce about 10 – 15 watts of rf – NOT full TX power! If you want the technical details, send me a email.

By design, it wants to end feed a random wire. The AT emits very little output power just mW during the tuning process. My system consists of a 75′ random wire, 3 – 6 ‘ copper ground rods, connected to the tuner with copper strap, and 5 ground radials of various lengths more to come.

No manual tuning is needed. No problem in tuning a long wire. The versatile AT can be used with a variety of vessels, even smaller boats that cannot use a long antenna element.

Unacceptable in a marine HF system. Automatic tuning No manual tuning is needed.

New to Ham Radio? This unit works great with the following Icom radios, IC-mkii, mkiig and pro3. What it really means is “ground this input if you want it to start tuning”. I normally turn my down to watts which is plenty.

This reduces the possibility of causing interference to other stations using the frequency. This allows you quick trouble-free frequency changes. Just connect the control cable and antenna icok and go! Still, a bit of a let down.

The main benefit of the ‘ is cost. Give it a better than average ground. Use a antenna of at least 35 feet.
