[ICOM] F. S. ICOM AT-500

[Earl Duda]

One (1) ICOM AT-500 automatic external tuner, covering 160 through 10 meters for sale.  Per ICOM’s published data:  the specific frequency range is 1.8-2, 3.5-4, 7-7.3, 10-10.5, 14-14.5, 18-18.5, 21-21.5 and 28-30 MHz.  Power capacity is 500 watts continuous, 1000 watts PEP. Impedance matching is 16.7 to 150 ohms to 50 ohms resistive. Minimum tune up power is 50 watts. The top panel access cover opens for adjustments for the Auto/Tune Preset switches, preset timers and Preset Indicators. The AT-500 rear panel features one input SO-239 jack and four output SO-239 coaxial antenna jacks. I have added jumpers internally so that if you have one feedline, you only have to connect to one of the SO-239 antenna jacks (#4).  Tune-up time is typically 4 to 7 seconds (3 seconds on the same band). The power requirement is 13.8 VDC or 117 VAC which is selectable from the rear panel. Dimensions and weight: 241x111x300mm or 9.5x4.4x12 inches, 6.4 kg or ~15 lbs.  The tuner is in good working condition, have been using it with an ICOM IC-7200 and a 7 band OCF dipole.  Included are: 117 VAC power cord, 13.8 VDC jumper in the rear, one (1) 50 ohm 2-foot coax with PL-259 on both ends, a non-ICOM cable to connect it to one of the following ICOM transceivers:  703, 706, 7000, 7100, 7200 and 7300, and the Instruction Manual (NOTE: I removed the AT-500 from use before trying the cable to connect it to the 7200.  I cannot vouch for the automatic feature since I didn’t use it.)  I am selling the AT-500 because I am buying a larger amplifier and need a tuner that can operate greater than 500 watts continuous.  While there is nothing wrong with it, the tuner is being sold as-is, no trades, no returns, no warranties, due to the age of the equipment. Payment by PayPal is acceptable.  Shipment via local UPS store.  $375.00 + shipping (CONUS only).  Email me at WA1MPB at Gmail.com for pictures or any additional questions.
