o Every ham band has a sub-band set, and for each of those, data related to the antenna and ATU tuning is also
stored. A “Sub-band chart” is on page 56 in the manual. If you so chose, using the frequencies on this chart for
TUNING, will pre-tune your amplifier to that frequency, with the ANTENNA that you have selected. EG: If ANT
1 and ANT 3 are programmed for 80 meters, when you “select the sub-bands that you feel ANT 1 will work
efficiently with, TUNING to those sub-bands using ANT1 will be “stored” in the ATU. Then when using ANT 2
and the sub-bands you chose for TUNING, those settings will be “stored” in the ATU. And those settings will be
remembered when your frequency and ANT choice matches those sub-bands. Be sure to make notations on
your Sub-band chart which antenna has “stored memories on particular sub-bands”.
o With a proper cable, the CAT connections the amplifier will know to the kHz the transceiver’s frequency.
o The 1.3K-FA amplifier has two different memory banks, A and B. It is possible to use the two different presets
when the amplifier operates at two different locations.
Before starting a matching process, the tuner measures the SWR of the system antenna system. If it is greater
than 5:1, the procedure does not begin and an alarm is displayed.
The internal tuner may be bypassed as follows:
o Totally.
o For single band.
o For single band and specific antenna.
It is always automatically bypassed:
o With the only receiving antenna set.
o With tunable antenna set.
o When “b” is selected in ANTENNA programming.
o On 70 MHz band.
Never use the internal tuner and an external tuner simultaneously as damage can be sustained by the internal
tuner. If you intend to use an external tuner, then disable the internal tuner.
