Similarly, if “BAND DATA“ is connected, check that the amplifier follows band changes
of the transceiver.
If it does not do so, then verify that your programming (or your link) has been correctly
made.
c) Use of the Automatic Tuner (Internal ATU)
To complete the programming it is necessary to match the antennas to the
amplifier by operating the “TUNE“ function (read the “TUNER“ chapter of
this manual).
We recommend that you select each band (with proper antenna) and then
program the tuner for the sub-bands within which you will operate.
Refer to the table in section 19 of this manual to select the appropriate sub -
bands for your operating preferences.
You are strongly advised to proceed with the utmost accuracy, not just match
the current frequency, but all the sub-bands that you are likely to use.
Matching all the antennas on all bands that are available, allows you to enjoy
all the features of the automatic linear.
To program the sub-bands, proceed as follows:
1) For every band find the central frequency in the table of each sub-band
(refer to section 19 of this manual). Then set the transceiver to that
frequency.
2) Next, set your transceiver to transmit a continuous tone (RTTY or FM).
3) Then press the [TUNE] key and then the PTT. The procedure for automatic
tuning will start. You will hear the ATU relays operate and when they
stop, the SWR will be at a minimum. Sometimes it is possible to improve
tuning by repeating this step.
4) Repeat the previous steps for all sub-bands of bands you wish to use.
5) Repeat the previous steps for other antennas of the same band after
having selected it using the [ANT] key.
Note: If the ALC link is not used, it is very important to reduce the transceiver power
to about 30 Watts during this operation.
The initial programming concludes after steps a), b), c).
