To select a tunable antenna, refer to the “TUN ANT” item on the main menu.
After selection, on the display, next to the number of the antenna in use a “t” will
appear. In this case the ATU will be bypassed.
Set "Kenwood" in the control box as the communication protocol used, the speed of
the communication is “owner settable.”
For the connection cable, refer to chapter 13.5.
4.5 Setting Up of an Antenna for Reception only
In some cases it may be necessary to transmit with one antenna and receive with a more
appropriate one.
A unique feature allows the Expert 1.5K-FA to have a very flexible management of the
available antennas.
To select a receiving antenna, refer to the “RX ANT” item on the main menu.
One of the following functions can be selected for each antenna:
• RTX: this is the "default" condition, an antenna marked RTX can be used for both
transmission and reception regardless of whether it is in the first or second column
in the "ANTENNA" menu item.
• RX Also: an antenna marked RX Also if, in the "ANTENNA" menu item, it is placed
in the first column it behaves like a normal RTX, if it is placed in the second column
it provides reception after the antenna selected in the first column has transmitted.
• RX Only: an antenna marked RX Only is an antenna suitable for reception only
(e.g. Beverage) it can be inserted in the first or second column, the important thing
is that an RTX is present in the other column. Since with linear OFF the INPUT1 is
connected directly to ANT1, to avoid the danger of transmitting when the linear is off
with a receive-only antenna, it is not possible to select ANT1 as RX Only.
The program admits only one RX Only.
In the "ANTENNA" menu item, in the last two cases, an "r" will appear next to the number
of the selected antenna (e.g. 3r). On the main screen, the indication of the receiving
antenna is placed above the transmission one.
QSK does not recommend this feature for timing reasons.
As an example, the screens are shown in the case of using ANT1 as “RX Also”.
