Operating Your AT2K
1-800-773-7931 WWW.PALSTAR.COM
Before Operating
1. To avoid possible damage to the AT2K set INPUT, OUT-
PUT, INDUCTOR, and POWER RANGE switches as out-
lined in the chart below before applying transmitter power.
2. Begin tuning with your transmitter/amp feeding the tuner
set at a low output power setting (50-100 Watts max).
Tuning
1. Select the band and frequency of desired operation.
2. Set TUNE and INDUCTOR controls to the suggested set-
ting before applying transmitter power (see chart). Actual
settings will vary from antenna. to antenna.
3. Set your transmitter/amplifier to a low power output. If
your transmitter has a TUNE position, select that position.
4. If you use a linear amplifier, set it to Standby. Do not use
the linear amplifier until the AT2K is tuned.
WARNING: DO NOT OPERATE THE AT2K
WITH THE COVER OFF.

MIN = 279
dle is a gear-driven precision mechanical counter. The end
stop readings on the turns counter are Zero and 279. Zero is
maximum inductance, and 279 is minimum inductance.
7. OUTPUT
Continuously adjustable output capacitor.
8. INPUT
Continuously adjustable input capacitor.
9. DIRECT-TUNED MODE SWITCH
Six-position rotary
switch selects an output connector as follows—
a.
DIRECT BYPASS
selects BYPASS COAX CONNEC-
TOR, bypassing the impedance matching circuit but pro-
viding SWR, FORWARD and REFLECTED power meter
readings.
b.
DIRECT COAX 1
selects COAX 1 CONNECTOR, by-
passing the tuner matching circuit but providing SWR,
FORWARD and REFLECTED meter readings.
c.
DIRECT COAX 2
selects COAX 2 CONNECTOR, by-
passing the tuner matching circuit but providing SWR,
FORWARD and REFLECTED meter readings.
d.
TUNED COAX 1
selects COAX 1 CONNECTOR
through the impedance matching T circuit.
e.
TUNED COAX 2
selects COAX 2 CONNECTOR
through the impedance matching T circuit.
