Selecting RX/TX/SUB-RX focus
When one or both splits are on, either of RX, TX or SUB-RX
can be chosen (focused) for subsequent control. Pressing
briefly button RX1-RX2-TX (Front panel, pos.10) cycles focus.
Current focus is indicated by a dot (LCD display, pos.2), and if
RX SPLIT is on, also by a digit for RX (RX1) and SUB-RX
(RX2) and font size of the displayed frequency.
The list of available selections changes according to the
current focus (LCD display, pos.11).
NOTE: When TX SPLIT is on and focus is set to TX, the list of
available selections contains only those selections which are
not RX-only.
When PTT goes active (transmission starts), the focus is changed automatically to TX but it can still be changed
by pressing the RX1-RX2-TX button. When PTT goes inactive (transmission stops), focus is returned to the
state where it was before PTT went active.
Basic antenna selections
Antenna selections are chosen simply by pressing one of the
buttons 1-7 below the LCD display. This will select the
corresponding selection displayed on the bottom line of LCD
for given focus, or, if TX-SPLIT is off and focus is not on SUB-
RX, for both RX and TX. Currently active antenna selection is
indicated by a LED lit next to the corresponding button 1-7.
If the list of antenna selections available for a certain focus
contains more than 7 items, button 7 is no more used for
choosing antenna selections, instead, it serves for changing
pages of selections.
NOTE: This is true even for TX focus, when RX-only antennas
are not displayed.
Alternatively, antenna selections can be selected consecutively using the left (YES) and right (NO) buttons.
IMPORTANT: If antenna selection is changed during transmit, the new antenna path is not built immediately.
The choice is remembered, and the new antenna path will be built when the transceiver returns to receive.
Meantime, LED above button corresponding to the new selection will flash, as well as the READY LED.
The last antenna selection is remembered in the non-volatile memory of SMD for all three paths in every band.
Events that may occur when changing antenna selections
There are several potential causes preventing a selected antenna path to be built. In such case, a message
explaining the cause of problem is displayed for a couple of seconds, and the previous path is restored.
Some of the control modules required for the chosen
•
selection may be occupied by one or more other SMDs,
i.e. the newly selected path would collide with already
built paths from other SMDs. Message "SMD [nr of
SMD] - occupies [nr of module]" is displayed.

RX split, indicated by digit next to dot and two frequencies
next to "Rx", focus on RX1
TX split, focus on Tx indicated by dot above "Tx"
This band contains list of 8 selections. Only 6 are displayed on
the 1st page, the 7th button is used to switch to 2nd page
2nd page of the same list of selections, displays the remaining
2 selections. 7th button is used to switch back to 1st page.
An attempted switch to a selection cannot be completed,
because module 41 is occupied by SMD 2
