1200 OPERATING MANUAL
ABOUT ATU OPERATION
Figure 1 depicts a situation where normal tuning via the $TU has been successfully completed, and the tuning data has
been stored in the $TU memory. The antenna system as seen by the transmitter is shown.
In Figure , the operator has changed freTuency, and the “
HI-SWR
” icon has appeared. The operator presses and holds
in the
[
TUNE
]
button for two seconds to begin impedance matching using the $TU.
If a high SW5 condition exists above 31), corrective action must be taken in the antenna system to bring the imped-
ance closer to 0 2hms. The $TU will refuse to memori]e settings on freTuencies where the SW5 exceeds 31. $ High
SW5 may indicate a mechanical failure in the feed system, and can lead to the generation of spurious signals causing
TVI, etc.
About ATU Memories
SWR (After tuning) Less than 1.5:1
The tuner settings are stored in the $TU memory.
SWR (After tuning) Greater than 1.5:1
Tuning data will not be retained in memory. If you return to the same freTuency, the tuning process must be re-
peated.
SWR (After tuning) Greater than 3:1
The “
HI-SWR
” icon will light up, and the tuner settings, if achieved, will not be memori]ed. 3lease investigate
the high SW5 condition and resolve the problem before attempting further operation using this antenna.
