Antenna Tuner
IC-756 OPTIONS
Linear Amplifiers
- IC-4KL HF 1 kW LINEAR AMPLIFIER: This is an all solid-state,
full-duty 1 kW linear amplifier including an automatic antenna tuner.
The IC-4KL is fully controllable from the IC-756. No need to tune and
no need to switch the operating band. Full break-in (QSK) operation is
possible. The amplifier/power supply unit and the remote control unit
are separated.
- IC-2KL HF 500 W LINEAR AMPLIFIER: All solid state linear
amplifier. The power amplifier unit can be separately set up from the
power supply unit.
Automatic Antenna Tuners, Antenna Element and Antenna Selector
- IC-AT500 HF 500 W AUTOMATIC ANTENNA TUNER: Includes automatic
antenna selector for 4 separate antennas.
- AH-3 100 W HF AUTOMATIC ANTENNA TUNER: Weather-proof tuner
matches the IC-756 to a long wire antenna for outdoor set up.
- AH-2b Antenna Element: A 2.5 m long antenna for mobile
operation with the AH-3. All bands between 3.5 to 29.7 MHz can be
matched.
- EX-627 AUTOMATIC ANTENNA SELECTOR: Automatically selects the
antenna for the selected ham band. Manual selection is also possible.
Max input power: 1000 W PEP
DC Power Supplies
- PS-85 DC POWER SUPPLY: Output: 13.8 V DC (20 A max.)
External Speakers
- SP-20 EXTERNAL SPEAKER: 4 audio filters; headphone jack; can
connect to 2 transceivers. Input impedance: 8 ohms; Max input power: 5
W

microphone including 2 connection cables for simultaneous connection
of 2 transceivers. [Up/Down] switches are included.
- SM-20 DESKTOP MICROPHONE: Unidirectional, electret microphone
for base station operation. Includes [Up]/[Down] switches and a low
cut function.
