Contact the site with comments or questions. New to Ham Radio? It seems to be a bit more rugged than my AH-4, which I toasted by trying to tune a 75 meter mobile whip on 40 meters.

Just connect the control cable and antenna wire and go! Getting the AT to autotune when it sees a new carrier seems impossible.

If you want the technical details, send me a email. Just lately it stopped doing that.

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. I normally turn my down to watts which is plenty. I purchased the unit while I was on holiday so I’d be forced to read through the manual for a xt130 days before trying to hook it up.

It appears it needs to also “be told” with a switch. As its a commercial unit and unlikely to be connected to a non-icom HF set, I can see why this has gone undetected.

One drawback to using the AT with the is that every time I would change bands or frequency ranges the tuner would automatically tune. Quick tune-up Improved tuning performance…the tune-up time is less than 3 seconds in any frequency on an HF marine band.

AT installation is simple. Low power tune-up The AT emits very little output power just mW during the tuning process. I recently got my brand new AT working.

Automatic tuning No manual tuning is needed. This causes the SG to emit a carrier and triggers the AT to start a tune cycle, sending the CW signal for as long as the tune cycle requires. Normally 8 Volts, when less than 1 volt is recieved a tune cycle will commence”. No manual tuning is needed. The pain that I experienced was the “start” input.

This unit works great with the following Icom radios, IC-mkii, mkiig and pro3. Improved tuning performance…the tune-up time is less than 3 seconds in any frequency on an HF marine band.

This allows it to be conveniently installed near the antenna element base. This allows you quick trouble-free frequency changes. Use a antenna of at least 35 feet. Sadly, it is not compatible with a balun By design, it wants to end feed a random wire.

Unacceptable in a marine HF system. At home I was feeding my balanced antenna with open-wire feeders directly from the AT with no choke on the coax and control line.

Icom AT-130 Antenna Tuner

If all antenna and ground requirements are met, the tuner will find a match pretty fast. No problem in tuning a long wire. The AT emits very little output power just mW during the tuning process. It only takes a couple of watts of RF to figure out what to do. I repair marine electronic equipment qt130 a living, so I have the advantage of being very at1130 with this unit.

The main benefit of the ‘ is cost. Retuning for a memorized frequency takes about 1. I’m af130 a devil of a time getting this tuner to talk with a Barrett marine HF radio.

Still, a bit of a let down. It is a capable tuner if you observe the following measures: It seems to gloss over the requirements if it is not connected to an Icom HF set. This reduces the possibility of causing interference to other stations using the frequency.
