One (1) ICOM AT-500 automatic external tuner,
covering 160 through 10 meters for sale.
Specifications: 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 (#3). 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 didnít 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 for
