the two is the real output power delivered from the amplier. The red TX sign illuminates (See

g 4-3) whenever KEY-IN input is keyed, i.e. the transceiver goes into transmit mode.

If the CAT connection is active and the amplier is in OPERATE mode, it will continuously track

the transceiver frequency and will automatically tune up when entering a new segment.

If there is no active CAT connection to the transceiver, and you start transmitting on a frequency

different from the indicated segment (and the amplier is in OPERATE mode), it automatically

senses your operating frequency, selects the corresponding segment, and tunes up on it. This

retuning takes less than one second and you are immediately ready to operate on the new

band. Example:

In the example, a signal frequency between 3650 and 3700kHz was applied and antenna No

3 (named DIPOLE) was last used there with tuning done by the user.

If in the OFF-menu (see S.6-2) AUTO ANTENNA CHANGE is set to OFF, then

the antenna number would not change.

A new frequency segment can be selected in three ways:

- as mentioned above, by the CAT system;

- by the internal frequency counter, after a short duration transmission from the transceiver

(with the amplier 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 BAND

SEGMENT up and down buttons.

- You can select the automatic segment change mode by means of the CAT (FREQ) leftmost

button.

d) A new antenna can be selected while in the MAIN-menu by the means of the ANTENNA up
