AR-Mini notes
Q: How to change VOLUME and SQUELCH settings in the BROADCAST
FACILITY and PRESET?
A: You need first to enter VFO by holding down the FUNC key and upper arrow
key once or twice until you enter VFO.
Then, to adjust the volume, press the dial knob. To adjust the squelch, press the dial
knob twice.
To return to BROADCAST FACILITY from VFO, hold down the FUNC key and press
the upper arrow.
To return to PRESET from VFO, hold down the FUNC key and press the upper arrow
twice.
Q: Why is AM or SW reception not improved although I have connected another
external antenna?
A: By default, AR-mini is using the built-in bar antenna for frequencies between
100 kHz and 30 MHz (not only up to 5 MHz as written in the manual). If you wish to
bypass this setting to use another external antenna between 100 kHz and 30 MHz:
-Hold down the FUNC key and press the dial knob to select setting number 17.
-Hold down the FUNC key and turn the dial knob to set “EXT”.
-To validate and to return to the original display, press the dial knob.
Please not that if the antenna type is not matched, or the antenna signal is too strong,
AR-mini will overload and reception sensitivity will be reduced. In most cases any large
external antenna will NOT improve reception, but a simple telescopic whip type
antenna will.
ANTENNA SELECTION
The correct antenna selection is important for shortwave reception. You will not obtain
correct measurements of sensitivity, IP3, unless the setting is changed to EXT.
