a memory tuning cycle if data from a previous tune on the present frequency
is available. Otherwise, it will perform a full tuning cycle, storing the tuning
parameters for future memory tunes. When tuning is complete, the
transceiver will return to receive mode. The Status LED on the AL-100 will
blink to indicate the status of the match (see table below for blink codes).
Watch the transceiver’s built-in SWR meter or use an inline SWR meter
between the radio and the tuner for a more precise SWR reading.
To start a memory tune from the tuner’s front panel, transmit a carrier (AM,
FM, or CW) and press the Tune button until the Status LED lights. Release
the Tune button, but keep the radio keyed, and wait for the memory tuning
cycle to end.
Full Tuning
In some cases you may want to perform a full tuning cycle even when
memory parameters are available. For example, you may have moved the
antenna, slightly changing its characteristics. You can force a full tuning cycle
that will cause the AL-100 to seek a better match than the one already stored
in memory for this frequency.
To start a full tune from the tuner’s front panel, transmit and hold a carrier
(AM, FM, CW) then press the Tune button and hold the Tune button for more
than 3 seconds, until the Status LED lights and then goes out, then release.
Keep the radio keyed for the full tuning cycle to end.
Bypass Mode
You may place the tuner in “bypass” mode, connecting the transmitter directly
to the antenna; no matching will be performed. To toggle between bypassed
and active mode, press the front panel Tune button on the AL-100
momentarily (0-1 sec) and release. The Status LED will flash three times to
indicate that the tuner is in bypass mode. Press the front panel Tune button
momentarily again to recall the previous tuner settings. The Status LED will
flash once to indicate that the tuner is no longer bypassed. This function is
useful when you wish to compare antenna performance with and without the
benefit of the tuner’s matching network.
