If set to "None ", transmitting briefly in RTTY or continuous key-down CW, you must
read the top left transmitted frequency.
Then return to STANDBY.
In the same way, if “BAND DATA“ is connected, check that the amplifier follows band
changes at the transceiver.
If it does not, verify that your programming (or your link) has been done correctly.
c) Use of Automatic Tuner
To complete the programming it is necessary to match the antennas to the
amplifier by operating “TUNE“ (read the “TUNER“ chapter of this manual).
We recommend you select each band (with available 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 you are likely to use.
Matching all the antennas on all bands available you will enjoy all the features
of the automatic linear.
Proceed as follows:
1)
Find the central frequency of the sub-band to tune in the table (refer to
section 19 of this manual) and set the transceiver to that frequency.
2)
Set your transceiver to transmit a continuous tone (RTTY or FM).
3)
Press the [TUNE] key, then the PTT. The procedure for automatic tuning
will start (you will hear the ATU relays operate) and then it will stop when
SWR is at a minimum. Sometimes it is possible to improve tuning by
repeating this step.
4)
Repeat the previous steps for all bands and sub-bands you want.
5)
Repeat the previous steps for any 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 50 Watts during this operation.
The initial programming concludes after steps a), b), c).
Operating
You need to exercise only a few precautions when using the amplifier thanks its high
level of automation.
ALC and CAT links are highly recommended.
If ALC is not used, SPE reminds you that it is better to lose a fraction of dB in
transmitted power, by slightly reducing the drive power, than to over-drive the amplifier
and have a poor quality transmission.
During transmission check the parameters on the display always, because SPE has
selected, designed and adjusted them with care.
SPE recommends (when using the ALC link) that the transceiver should be set to its
maximum output power, the ALC will reduce the driving power to the optimum driving
level.
To reduce the linear output, if required, it is then necessary only to set the amplifier to
“MID” or “LOW” with the [POWER] key.
