AT-11MP Antenna Tuner project.
At one of our first meetings we discussed witch projects we would like to do.
Among the input was an antenna tuner. The choice fell on the AT-11MP.

The AT-11MP desktop auto-tuner:

The AT-11MP is a major step forward in tuner design. Major changes from the AT-11 Baseline v2.5 include dual cross needles, measuring forward / reflected power and SWR, and a remote head option allowing you the ability to mount the AT-11MP in your trunk or other out of the way place and still control the tuners function and get a visual indication of your tuned SWR via LEDs.

The AT-11MP also features an ICOM or Alinco interface. Keep in mind that the AT-11MP will function with any radio, from a Heathkit, to a Collins, to a Ten-Tec, the Icom 706 interface allows the user to activate the tune feature by pressing the tune button on the front panel of the radio. This can be very handy if the tuner needs to be up away from easy arm reach on a hutch or on a shelf due to "shack clutter".
