AT-Auto Tuner CablesThe AT-AUTO sends and receives serial data to/from the associated radio via the radio's serial port. This is commonly referred to as Computer Aided Tuning or CAT. In order for the radio and the AT-AUTO to be able to communicate serially, an appropriate CAT cable must be used.
Because there is no defacto standard for CAT, there are variations in connectors and pin assignments from manufacturer to manufacturer. Therefore, there are unique AT-AUTO CAT cables for Elecraft, Kenwood, TenTec, Yaesu, and others. The CAT cables themselves are nearly identical, with minor variations in the specific connector and pin assignments.
ICOM has their own CAT implementation known as CI-V which uses entirely different protocols. ICOM radios, therefore, do not use the CAT cable, but instead use a CI-V cable.
Cable Sets consist of a Firmware Update Cable, A CAT/CI-V Cable, and in the case of some Kenwood radios, a Tuner-Handshake Cable. Schematic diagrams of the various cables are provided in the AT-AUTO user manual.
Purchase Cables for the AT-Auto Tuner
|"Universal Serial Interface" for the AT-AUTO. It comes supplied with three identical serial cables and the interface board. The universal interface eliminates the need for different radio-specific cables and only uses typical 9-pin serial cables. The interface has three switches that permit quick selection of mode as well as radio-specific settings. This is the best option for your situation and it less expensive than buying multiple sets of cables. A PDF manual is available here.||$58.00|
|ICOM Interface Cable Set, 6 feet long. The Icom Tuner-Handshake is much simpler to implement with no special circuit boards required. This feature is incorporated into the ICOM CI-V cable.||$40.00|
|Firmware Update Cable, 6 feet long. The AT-AUTO employs a microprocessor and the programming (firmware) may be updated by the user as new features and improvements are made. This requires a standard 9-pin male-to-female serial cable, which we refer to as the Firmware Update Cable.||$7.50|
|Elecraft Serial Data Interface Cable Set, 6 feet long||$30.00|
|TenTec Serial Data Interface Cable Set, 6 feet long||$30.00|
|Kenwood/Yaesu Serial Data Interface Cable Set, 6 feet long||$30.00|
|New! AT-AUTO Power Cable||$28.00|
AT-Auto Tuner Upgrades
Although currently out of production, we are dedicated to providing outstanding product support for the legacy AT-AUTO tuner. Until now, that product support has consisted primarily of repair and firmware updates. However, in to ensure AT-AUTO operational longevity and to prevent product obsolescence, we are in the process of developing a series of hardware improvements for the legacy AT-AUTO.
As those hardware improvements occur, they will be made available to AT-AUTO owners.
One of the most common complaint areas concerns the AT-AUTO's stock meter. Meter problem areas have been "sticking" needle movements due to static electricity accumulation, illumination "hot spots" and difficulty obtaining replacement incandescent meter lamps. Other complaints involve meter face clutter and lack of resolution.
In order to solve the meter issues, we developed a replacement meter using better plastics that prevents the static electricity build-up and is back-lit with three LEDs, providing nearly uniform illumination and eliminating the incandescent lamp burnout/replacement issues.
