AR3000A -

evolution

, the wider horizons

wide band all mode mobile / base receiver 100 kHz - 2036 MHz

The AR3000A is an evolutionary step forward from the highly acclaimed AR3000,

many major improvements have been implemented at the requests of enthusiastic

listeners and commercial organisations. Search and scan speed has been

increased to an unprecedented 50 increments per second.

Your listening horizons are truly extended with receive coverage from 100 kHz

all the way up to 2036 MHz without any gaps in the range. The AR3000A provides

an extremely wide coverage with high level of performance and versatility from

long wave through short-wave, VHF and onward to the upper limits of UHF.

The high level of performance is achieved by using 15 band pass filters before

the GaAsFET RF amplifiers unlike many other receivers which rely largely on

broad band amplifiers. This ensures high sensitivity through the entire coverage

with outstanding dynamic range and freedom from intermodulation effects.

Not only will the AR3000A cover this extremely wide range, it will allow listening

on any mode: NFM, WFM, AM, USB, LSB and CW.

Tuning rates are selectable from an fine 50 Hz step for SSB and CW right the way

up to 999.95 kHz for the TV and VHF broadcast bands, x10 increase and SLOW

buttons quickly change tuning rates for convenience and speed. A free running

rotary tuning control provides the best possible method of user-interface along

with the numeric keypad.

An RS232 port is provided as standard enabling full remote control of the

receiver.

There are 400 memory channels arranged as 4 x 100 and 4 search banks,

frequency lockout, priority, frequency offset, step adjust etc all make the

AR3000A a feature packed unit.

The AR3000A is powered from 12V d.c., a suitable mains power supply is

provided with the receiver. Other accessories include a telescopic whip aerial,

d.c. lead and operating manual.
