BARRETT PRC-4090 TACTICAL HF SDR TRANSCEIVER - INSTALLATION
the transceiver and repeat the above procedure. The result should be the same,
except that the tune cycle may take longer. If the above procedure does not
give the results as indicated, check that the antenna length and connections are
correct and re-check all ground (earth) connections.
Note: When received, the Barrett 911 automatic antenna tuner memory system will
usually not have any pre-stored tuning information appropriate to your installation.
To allow the 911 to ‘learn’ its tuning information simply proceed from one channel
to the next allowing the normal tune cycle to take place. Each successful tune is
‘memorised’ so that when that channel is re-selected, the tuner will almost instan-
taneously retune to that frequency.
