In the example, a signal frequency between 3650 and 3700kHz was applied and antenna No 3 was last
used there with tuning done by the user (USR).
If in DEF sub-menu (see S.5-6) AUTO ANTENNA CHANGE is OFF , then the antenna
number would not change with frequency and remains No 1.
c) A new frequency segment can be selected in two ways:
as mentioned above, apply from the transceiver a short duration signal (with the amplifier in OPR
mode) - a single word in SSB or a dot in CW (even at 40 wpm) would be enough;
manually, in the MAIN-menu by selecting the desired segment by means of the
Then confirm it with
d) A new antenna number can be selected while in the MAIN-menu. Press the
select an antenna number, then confirm it with
If you have stop on a certain segment or antenna, but you do not confirm your
choice within 10 seconds, the display will automatically revert to the previous
segment/antenna.
You will notice that while going through antennas and frequency segments, the inscriptions for antenna
number and type of tune-up are shown in lowercase characters. This means that they are not those for
which the amplifier is currently tuned up. If you pass through the current segment, you will see that
UPPERCASE characters are used. While scanning through the options you can see for which segments
and for which antennas in them you have DEF (default) or USR (pre-programmed by the user). You can
scan through these values without affecting the operation of the amplifier. New settings only take effect
after having been confirmed by using the
e) The MAIN-menu consists of four sub-menus which can be selected by pressing the
fig.3-2 and S.8).
The purpose and use of these four sub-menus are described in the next sections 4-1 to 4-5.
f) In order to turn the amplifier off, press the red
amplifier for a long time (more than 30 minutes), it is best to turn off the amplifier using the Main Power
switch (on the main amplifier chassis) as well.
