When using the TA-90 autotune system ensure that;
the whip antenna is undamaged, the white antenna
insulator is clean and undamaged, the red wire
feeding the top of the insulator is clear of metalwork
by at least 50mm and that the ground connection to the
TA-90 Tuner is adequate.

When using a tapped whip antenna always ensure that
the tap selected corresponds to the channel/frequency
in use on your HF-90 radio (usually the channel/
